Camelina sativa asasustainable and feasible feedstuff for broiler poultry species: AreviewReviewYazavinder Singh, Marco Cullere, Eva Tmov, Antonella Dalle ZotteCzech J. Anim. Sci., 2023, 68(7):277-295 | DOI: 10.17221/29/2023-CJAS Camelina sativa can be identified asapromising oilseed crop due toits short growth cycle, tolerance todrought and frost, low-input requirements, resistance topests and diseases, feed, and non-feed applications. Compared toother Brassicaceae family plants, camelina is mainly distinguished byhigh levels ofn-3 polyunsaturated fatty acids and antioxidant content. However, camelina contains secondary plant metabolites, such asglucosinolates, phytic acid, sinapine, etc., and their presence limits the use ofcamelina by-products (oil, seed or cake) inpoultry feeding. The breakdown ofthese compounds forms complexes that can inhibit digestive enzymes, reduce the absorption ofnutrients, and ultimately modify product quality. The content ofthese anti-nutritional compounds and plant seed quality can be modified byvarious techniques: hybridisation, mutation induction, gene engineering, etc. Moreover, methods such asinfrared irradiation, multi-enzyme and copper supplementation, etc., can counter or mitigate the effect ofplant secondary metabolites present incamelina seed or cake. Ingeneral, dietary inclusion ofcamelina seed or cake athigh inclusion levels (> 10%) worsened the nutrient digestibility and thus reduced growth performances. However, carcass traits and meat proximate composition were comparable inbirds-fed diets containing camelina by-products. The fatty acid profile ofmeat cuts and abdominal fat wassignificantly higher inalpha-linolenic acid and lower n-6/n-3 ratio, thus promoting the healthiness ofproducts for human consumption. Also, the dietary inclusion ofcamelina did not modify the sensory profile ofthe products. The present article is acomprehensive and critical review ofresearch carried out toimprove the quality ofcamelina and its by-products tobe used inbroiler poultry feeding. This review gives information on the feeding value ofcamelina by-products, aswell asasurvey ofthe literature on their use inpoultry diets toevaluate digestibility, performance, carcass traits, and meat quality. |

Impacts and mechanisms of biochar on soil microorganismsReviewKai Huang, Jun Zhang, Guangming Tang, Da Bao, Tangyu Wang, Deping KongPlant Soil Environ., 2023, 69(2):45-54 | DOI: 10.17221/348/2022-PSE Biochar is a carbonaceous material derived from the pyrolysis of carbon-rich biomass that has attracted increasing research and attention because of its ability to enhance soil carbon storage, increase soil fertility, fix and transform pollutants in soil, and improve the soil environment. These enhancements directly or indirectly affect soil microorganisms’ metabolic activities and community structure. This paper reviews the effects of biochar on soil physicochemical properties, enzyme activities, nutrients, contaminants, and related microbial activities. In addition, this work summarises the possible mechanisms involved in the interaction between biochar and microorganisms and the potential hazards associated with biochar use. Finally, this study aims to provide a theoretical basis for future related research. |
A preliminary study on suitability of growing ginseng (Panax ginseng Meyer) in western Himalayan regionOriginal PaperSwati Walia, Pawan Kumar, Dinesh Kumar, Rakesh KumarPlant Soil Environ., 2023, 69(2):71-80 | DOI: 10.17221/288/2022-PSE Panax ginseng Meyer is one of Asia’s most popular medicinal plants, with triterpene saponins as principal bioactive compounds. The present study investigates the possibility of ginseng cultivation in Lahaul & Spiti, Himachal Pradesh, India in the Western Himalayas focusing on growth characteristics, and ginsenoside content in the roots. Plant growth parameters increased with an increase in the crop age and reached maximum maturity at the age of five years along with the production of a good amount of seeds and roots. Root fresh and dry weight of the five-year-old plant was 142.6 g and 45.5 g, respectively, which almost doubled as compared with the four-year-old plant. The HPLC analysis of P. ginseng roots leads to the identification of 14 compounds representing 31.81 ± 2.89 mg/g of total ginsenoside contents, where Rb1, Rg2 and Re were found to be major ginsenosides with 7.53 ± 0.37, 7.04 ± 0.61 and 3.77 ± 0.26 mg/g content. Protopanaxadiol (PPD) and protopanaxatriol (PPT) represent the major classes of ginsenosides present in the ginseng roots with a 0.98 ratio of PPD/PPT. Our studies revealed that the soil and climate of the Lahaul and Spiti district of Himachal Pradesh State in the Western Himalayas are suitable for the cultivation of P. ginseng with good content of ginsenosides in five-year-old roots. |
Market entry strategy and export destination in the Spanish wine industryOriginal PaperRaul Serrano, Juan Ramn Ferrer, Silvia Abella, Vicente PinillaAgric. Econ. - Czech, 2024, 70(12):621-632 | DOI: 10.17221/107/2024-AGRICECON This paper analyses the market entry strategy of the Spanish wineries and their destination markets. For this purpose, channel adjustment was analysed. The novel aspect of this research is the use of exports on a winery level, basing the explanation of their export performance on a combination of internal decisions of the companies, and characteristics of the wine destination markets, in accordance with the purchasing patterns of their consumers. The results revealed the importance of strategic adjustment between winery and market destination, even though the importance of adjustment depends on the level of exports. Thus, channel adjustment is important for the probability of export and export intensity. |

Incidence of thermophilic, grass and rare arable weeds in cereal fields in the Czech and Slovak RepublicOriginal PaperMichaela Kolov, Ludk Tyer, Theresa A. Reinhardt Piskkov, Jana MjekovPlant Soil Environ., 2023, 69(3):131-140 | DOI: 10.17221/439/2022-PSE Our objectives were to characterise arable weeds of the Czech and Slovak Republic in cereals, especially considering important groups of species: thermophilic, weedy grasses, and rare and endangered species. The three-year phytocoenological survey was conducted from 2006 to 2008 in five climatic regions and eight different soil types. 379 relevs were recorded, and 281 weed species were found. The effects of both the climatic region and soil type were found to be statistically significant. Species richness increased with altitude. Several species were distinctly associated with soil type, from fertile chernozems to less fertile cambisols, while fluvisols were strongly associated with e.g. Calystegia sepium (L.) R. Br. The incidence of species outside their expected regions generally fit two categories: the most pervasive weeds found almost in all climate regions, such as Echinochloa crus-galli (L.) P. Beauv., or rare weeds in higher altitudes than expected, such as Lolium temulentum L. Rare and endangered species were more likely to be found in a colder climate and poorer soils, and this is linked to less intensive management; however, not all endangered arable species can tolerate such conditions. Even though this data is not recently collected, this is still valuable information on the distribution of weedy species, especially concerning the current interest in maintaining biodiversity. |

Assessment ofaboveground biomass and carbon stock ofsubtropical pine forest ofPakistanOriginal PaperNizar Ali, Muhammad Saad, Anwar Ali, Naveed Ahmad, Ishfaq Ahmad Khan, Habib Ullah, Areeba Binte ImranJ. For. Sci., 2023, 69(7):287-304 | DOI: 10.17221/125/2022-JFS The presented study estimated the aboveground biomass (AGB) ofPinus roxburghii (chir pine) natural forests and plantations, and created biomass maps using arelationship (regression model) between AGB and Sentinel-2 spectral indices. The mean AGBand BGB(belowground biomass) ofnatural forests were 79.54 Mg·ha–1and 20.68 Mg·ha–1, respectively, whereas the mean AGBand BGBofplantations were 94.48 Mg·ha–1and 24.56 Mg·ha–1, respectively. Correlation showed that mean diameter atbreast height (DBH) and mean height have weak relationships with AGB, and BGBhas shown correlation coefficients (R2=0.46) and (R2=0.56) for polynomial models. Regression models between AGB(Mg·ha–1) ofPinus roxburghii natural forest and Sentinel-2 spectral indices showed astrong relationship with Ratio Vegetation Index (RVI) with R2 = 0.72 followed byNormalized Difference Vegetation Index (NDVI) and Atmospherically Resistant Vegetation Index (ARVI) with R2=0.70. Incontrast, the lower performance ofspectral indices has been shown inregression with plantation AGB. Correlation coefficients (R2) were 0.41, 0.41, and 0.40for RVI, NDVI, and ARVI, respectively. All indices showed that the distribution ofAGBdata was not the best fit with the linear regression model. Therefore, non-linear exponential and power models were considered the best fit for NDVI, RVI, and ARVI. Abiomass map was developed from RVI for both natural forests and plantation because RVIhas the highest R2and lowest P-value. |
Psychoactive substances in soils, plants, freshwater and fish: A mini reviewReviewKateina Vejvodov, Radka Kodeov, Pavel Hork, Lubo Borvka, Pavel TlustoSoil & Water Res., 2023, 18(3):139-157 | DOI: 10.17221/58/2023-SWR This review focuses onthe behaviour offour psychoactive compounds (carbamazepine, tramadol, sertraline and citalopram) inthe environment. The review presents how they may directly affect freshwater systems, soils and living organisms and towhich extent. The transformation ofthese very stable compounds insoils were controlled byoxidation, demethylation, decarboxylation and hydroxylation. Sorption toorganic matter and clay particles controlled their mobility. Despite their expected sorption insoils, sediments and sludge, all compounds can betaken up byplants and byfish. Inplants, all compounds and several oftheir metabolites were found inthe leaves, indicating the mobility and transformation ofthe compounds within the plant systems. Factors that control the compounds mobility inplants were found tobe the pH ofsoils and the xylem flow. Asfor fish, many ofthe compounds were found inthe brain and muscles offish, some ofwhich, depending onthe species, affected the behaviour ofthe fish. The implications ofthese compounds sowidely present inthe environment indicate the need for certain measures tobe put into place toprevent these compounds from continuously entering plant and animal systems. |
Biodegradation of chlorpyrifos by soil bacteria and their effects on growth of rice seedlings under pesticide-contaminated soilOriginal PaperThanakorn Saengsanga, Nutthida PhakratokPlant Soil Environ., 2023, 69(5):210-220 | DOI: 10.17221/106/2023-PSE This study identified three soil bacteria (NRRU-BW3, NRRU-BW3, and NRRU-TV11) that degrade chlorpyrifos, produce indole-3-acetic acid, and exopolysaccharides under pesticide stress. The results revealed that soil bacteria were identified as Priestia megaterium NRRU-BW3, Bacillus siamensis NRRU-BW9, and Bacillus amyloliquefaciens NRRU-TV11. These strains showed the ability to produce indole-3-acetic acid (IAA) and exopolysaccharides (EPS) in chlorpyrifos. Moreover, these bacteria can degrade chlorpyrifos (CP) in an aqueous medium, anda 33–52% degradation rate was observed after 14 days of incubation. Inoculation with the NRRU-TV11 significantly increased (P < 0.05) plant height, root length, biomass and vigour index of rice seedlings compared to uninoculated controls in chlorpyrifos-contaminated soil. The findings demonstrated the beneficial effects of indigenous NRRU-TV11 on rice seedling development and chlorpyrifos degradation and recommended this strain as a potential replacement for plant growth improvement and environmental bioremediation of pesticide-contaminated agricultural soils. |
Influence ofPaulownia fortunei (Seem.) Hemsl. roots onpreferential flow inthe red soil hilly regionOriginal PaperZhuo Tian, Shuaipu Zhang, Qinxue Xu, Mingfeng Bi, Jianhua HeSoil & Water Res., 2023, 18(2):89-101 | DOI: 10.17221/140/2022-SWR Preferential water flow in soil significantly affects runoff, water infiltration, storage, groundwater environment, and soil stability. Plant roots positively affect preferential flow development. This study explored the relationship between the root system of Paulownia fortunei (Seem.) Hemsl. and preferential flow using dyeing tracer test and image analysis techniques. A typical red soil hilly region on the outskirts of Guilin City (Guangxi, China) was selected as the study area. A Bright Blue solution was used to visualize the pathways followed by the infiltrated water in simulated rainfall experiments, and Image Analyzer of Plants was used to analyze the root length, surface area, and volume. The results revealed significant differences in the root surface area density of coarse roots (RSAD-CR) and length index of preferential flow (LI) among soil profiles at various distances from the tree trunk. The root volume density of coarse (RVD-CR) and total roots (RVD-TR), the root length density of coarse roots (RLD-CR), and RSAD-CR were significantly correlated with the characteristics of dyeing morphology. Conversely, the root length density and root surface area density of fine (RLD-FR and RSAD-FR, respectively) and total roots (RLD-TR and RSAD-TR, respectively), and the root volume density of fine roots (RVD-FR) were not significantly correlated with the characteristic parameters of dyeing morphology. The root systems of P. fortunei were critical for enhancing soil water infiltration and developing preferential flow in red soil hilly regions. Coarse roots had a greater impact on the development of preferential flow than fine roots, and root volume had a greater influence on preferential flow development than root length and root surface area. This study contributes to a better understanding of the hydrological cycle at the plant-soil interface in red soil hilly regions. |
Long-term high temperature stress decreases the photosynthetic capacity and induces irreversible damage inchrysanthemum seedlingsOriginal PaperYuanda Zhang, Zaiqiang Yang, Peijuan Wang, Chao XuHort. Sci. (Prague), 2023, 50(2):159-173 | DOI: 10.17221/28/2022-HORTSCI To study the effects of long-term and short-term high temperature stress and recovery on the physiological functions and appearance quality of chrysanthemums, a controlled experiment with chrysanthemums was conducted. The treatments were 25 C for 3 days (T1D3), 25 C for 9 days (T1D9), 41 C for 3 days (T2D3) and 41C for 9 days (T2D9). The results indicated that there is no significant difference between the T1D3 and T1D9 groups. Conversely, the total chlorophyll content (Chl), net photosynthetic rate (PN), and maximum quantum yield of Photosystem II (PSII) (FV/FM) under T2D3 and T2D9 decreased by 27.07%, 43.30%, 5.62%, and 44.85%, 68.22%, 8.29%, respectively. The JIP-test results showed that the T2D9-stressed plants had a lower efficiency and functional antenna size, and a higher activity of the reaction centre than T2D3. The contents of malondialdehyde, soluble protein and proline increased by 3.67 nmol/g FM, 298.75 μg/g, and 192.99 μg/g, and the antioxidant enzymes activities were inhibited significantly under T2D9. After the stress was relieved, Chl, PN, and FV/FM under T2D3 recovered to the same level as T1D3, while T2D9 did not. Furthermore, the diameter of the flowers in T2D3 showed no significant difference with the chrysanthemums under T1D3. However, the plants in T2D9 recovered poorly. Both the diameter of the flowers and the anthocyanin under T2D9 reduced significantly comparing with T1D9, indicating that the damage in the chrysanthemum seedlings caused by long-term high temperature was irreversible. |

Transcriptome profiling ofSorghum bicolor reveals cultivar-specific molecular signatures associated with starch and phenolic compounds biosyntheses and accumulation during sorghum grain developmentOriginal PaperLi Wang, Derang Ni, Fan Yang, Lin Lin, Yubo Yang, Chongde Sun, Xingqian Ye, Jinping Cao, Xiangli KongCzech J. Genet. Plant Breed., 2023, 59(4):235-252 | DOI: 10.17221/16/2023-CJGPB Sorghum isan important crop, and starch and phenolic compounds are major and important components inthe sorghum grain. However, the underlying critical genetic elements contributing tothe rich portfolio ofnutrients insorghum grains are largely unknown. Transcriptomic methods were employed tocharacterize the expression patterns atfive different grain developmental stages ofHongyingzi (an important brewing sorghum), and another two grain sorghums, Jinuoliang 1 and Hongliangfeng 1, for comparison. The uniquely expressed genes were identified ateach developmental stage ofHongyingzi when compared with the other two sorghum cultivars. The co-regulated genes atdifferent developmental stages and the regulatory network were determined; the determinant genes and single-nucleotide polymorphisms located atthe promoters ofthese genes involved instarch and phenolic compounds biosynthetic pathways were also identified. These results will provide insights into the potential regulatory network and further contribute tothe clarification ofthe key determinant genes involved inthe biosyntheses ofstarch and phenolic compounds. Meanwhile, some new transcripts and genes were identified atfive different developmental stages ofgrains of the three sorghum cultivars. Our work can provide impetus for further study ofthe genes responsible for the biosynthesis ofstarch and phenolic compounds inthe sorghum grain, and pave away for functional validation ofabatch ofpotential genes and single-nucleotide polymorphisms proposed incurrent work. |
Genetic diversity among coloured cotton genotypes in relation to their fibre colour and ploidy level based on SSR markersOriginal PaperRevanasiddayya, Jayaprakash Mohan Nidagundi, Bashasab Fakrudin, Prakash Kuchanur, Lingappa Neelagiri Yogeesh, Shivanand Hanchinal, Talagunda Chandrashekar Suma, Gururaj Sunkad, Bharamappanavara Muralidhara, DodCzech J. Genet. Plant Breed., 2024, 60(1):12-24 | DOI: 10.17221/12/2023-CJGPB Genetic diversity isreferred toas any variation atthe phenotypic, DNA orgenomic level ofan individual, population orspecies. The appraisal ofdiversity isimportant tounderstand its pattern and evolutionary relationships between germplasms orgenotypes, which will aid insampling the genetic resources inamore systematic manner for conservation and crop improvement. The present study employed 50 simple sequence repeat (SSR) markers linked tothe yield and fibre quality/colour traits for estimating the genetic diversity in33 cotton genotypes ofdiploid and tetraploid species differing infibre colour. The diversity analysis was performed inGenAlEx (Ver. 6.41) and Powermarker (Ver. 3.25) while DARwin (Ver.6.0.21) software was used toestablish the phylogenetic relationships following neighbour-joining (NJ) and unweighted pair group method with arithmetic (UPGMA) mean method. Markers generated 186 polymorphic loci asgenotypic data with anaverage of3.72 alleles and anaverage polymorphic information content (PIC) value of0.59 per SSR locus. The NJ and UPGMA grouped 33 genotypes into three major clusters I, II and III consisting of21tetraploid Gossypium hirsutum, 10 G. arboreum coloured and 2 white cotton genotypes, respectively. Inthe PCA, the first two components (PC1 and PC2) explained 74.69% ofthe variation and the biplot plotted the 33 genotypes inthree groups. The study established the diverse nature of33 cotton genotypes based ontheir fibre colour and ploidy level. With confirmation ofthe prevalent genetic diversity, wesuggest that hybridisation can beplanned among diverse genotypes tounleash greater variation inthe fibre colour orto derive superior cross combinations. |

Ameliorative effect ofyeast cell walls on broiler chickens’ performance and gut health under coccidiosis challengeOriginal PaperShawkat Abdulrazaq M'SadeqCzech J. Anim. Sci., 2023, 68(8):346-355 | DOI: 10.17221/24/2023-CJAS This study was conducted toevaluate the efficacy ofyeast cell wall parts (YCW) inreducing the severity ofcoccidiosis inbroiler chickens. One-day-old Ross 308 chicks (n=320) were randomly allocated to32 floor pens intwo rooms with a2 4 factorial arrangement oftreatments. Factors were (1) challenge: negative or positive byroom, (2) feed additive: control (none), anticoccidial (salinomycin at60mg/kg), YCW 0.1% or 0.2%. On day 8, none-challenged room was inoculated with saline, and challenged room was inoculated with 5 000 Eimeria tenella oocysts. Performance results showed thatin challenged birds, feed conversion ratio (FCR) and weight gain (WG) were poorer than inunchallenged birds on day 24 and 35. Birds given anticoccidial and YCW had improved FCR and WG (P=0.01) over the control group. Challenge and additive interactions were observed on day 24 and day 35 for FCR and WG (P=0.01) and for feed intake on day 24 (P=0.01). Challenged birds fed YCW on days 24 and 35 had higher WG and better FCR compared with both challenged and non-challenged controls and anticoccidial treatment. Coccidial challenge increased crypt depth (CD), villous tip and base width, and villous surface area and decreased villous height tocrypt depth ratio (VH : CD) and villous height (VH). Birds fed YCW exhibited significantly decreased CD, villous tip width, villous base width, villous surface area and increased VH, VH : CD incomparison tothe control group. Challenged birds fed YCW had significantly lower bursa ofFabricius follicle length compared tobirds fed the control diet. Challenged birds had significantly increased serum alanine transaminase (ALT) and aspartate aminotransferase (AST) concentrations than non-challenged birds. Inconclusion, these results demonstrated that the yeast cell wall has the ability tocontrol coccidiosis. |

Extraction and enzymatic modification ofdietary fibre from purple aubergineOriginal PaperSuwalee Fong-in, Kamonlak Wicharaew, Pattaramon Phalapan, Trakul PrommajakCzech J. Food Sci., 2023, 41(4):304-312 | DOI: 10.17221/84/2023-CJFS This research scrutinised the opportunity ofupcycling waste from the food industry byextracting dietary fibre from purple aubergine. One ofthe challenges addressed was enzymatic browning, which negatively influenced the quality ofthe fibre extracted from fresh aubergine. Various pre-treatment procedures were assessed, including using citric acid, sulphite immersion, peeling and thermal processing, todetermine their effects onextraction yield, colour, and the functionality ofthe resultant dietary fibre. Findings indicated that apre-treatment method involving aubergine peeling, sulphite solution immersion, and subsequent steaming before extraction produced optimal results, enhancing both whiteness index and water-holding capacity. Experiments were conducted with traditional enzymes supplemented with cellulase, xylanase, and lipase for enzymatic extraction. Theaddition oflipase notably elevated the extraction yield and water-holding capacity, albeit with anundesired darkening effect onthe dietary fibre. Incontrast, the application ofxylanase emerged asthe most effective treatment, delivering the highest overall quality for the derived dietary fibre. |

Therefore, the impact ofpermanent cultivation was evaluated, through modelling, onindicators ofrecent alluvial soil quality and production inplantations ofMusa paradisiaca L. var. Harton, inthe Aguaytia River valley, Peru. The treatments were areas with permanent plantain plantations of2 (T0), 15 (T1), 4 (T2), and 5 (T3) years ofmanagement, evaluating soil physicochemical indicators and plantain production indicators. The results show significant differences for all yield and soil indicators evaluated, except for bulk density (Bd), clay fraction, soil organic matter (OM) and N. The modelling determined asignificant positive impact onBd and asignificant negative impact onpH, P, pseudostem diameter and height, commercial fingers and bunch weight. Inconclusion, the modelling shows trends ofquality and yield reduction in15 years ofpermanent management ofplantain Var. Harton, and compromises the sustainability ofthe agroecosystem inthe medium term. |
The use offunctional amino acids indifferent categories ofpigs – AreviewReviewN Hodkovicova, S Halas, K Tosnerova, K Stastny, M SvobodaVet Med - Czech, 2023, 68(8):299-312 | DOI: 10.17221/72/2023-VETMED The present review deals with aparticularly important topic: the use offunctional amino acids indifferent categories ofpigs. Itis especially relevant inthe context ofthe current efforts toreduce the use ofantibiotics inpig farming and the search for possible alternatives toreplace them. The review isbased onthe definition that functional amino acids (FAAs) are classified asdispensable amino acids, but with additional biological functions, i.e., not only are they used for protein formation, but they are also involved inregulating essential metabolic pathways toimprove health, survival, growth, and development. Wedescribe the mechanism ofaction ofindividual FAAs and their potential use inpigs, including glutamate, glutamine, arginine, branched-chain amino acids (i.e.,leucine, isoleucine, and valine), tryptophan and glycine. The work isdivided into three parts. The first part deals with the FAAs and their role inthe overall health ofsows and their offspring. The second part describes the use offunctional amino acids inpiglets after weaning. Part three examines the use offunctional amino acids ingrowing and fattening pigs and their impact onmeat quality. |
Selected neonicotinoids and associated risk for aquatic organismsReviewA Strouhova, J Velisek, A StaraVet Med - Czech, 2023, 68(8):313-336 | DOI: 10.17221/78/2023-VETMED Neonicotinoids are one ofthe newest groups ofsystemic pesticides, effective onawide range ofinvertebrate pests. The success ofneonicotinoids can beassessed according tothe amount used, for example, inthe Czech Republic, which now accounts for 1/3 ofthe insecticide market. The European Union (EU) has arelatively interesting attitude towards neonicotinoids. Three neonicotinoid substances (imidacloprid, clothianidin and thiamethoxam) were severely restricted in2013. In2019, imidacloprid and clothianidin were banned, while thiamethoxam and thiacloprid were banned in2020. In2022, another substance, sulfoxaflor, was banned. Therefore, only two neonicotinoid substances (acetamiprid and flupyradifurone) are approved for outdoor use inthe EU. Neonicotinoids enter aquatic ecosystems inmany ways. InEuropean rivers, neonicotinoids usually occur innanograms per litre. Due tothe low toxicity ofneonicotinoids tostandard test species, they were not expected tosignificantly impact the aquatic ecosystem until later studies showed that aquatic invertebrates, especially insects, are much more sensitive toneonicotinoids. Inaddition tothe lethal effects, many studies point tosublethal impacts - reduced reproductive capacity, initiation ofdownstream drift oforganisms, reduced ability toeat, orachange infeeding strategies. Neonicotinoids can affect individuals, populations, and entire ecosystems. |
Inorganic improver and straw returning promote corn growth and improve the quality of saline soilsOriginal PaperJipeng Wang, Junchuan Huang, Xinyu Hou, Quangang Yang, Hong Pan, Hui Wang, Fei Han, Yanhong Lou, Yuping ZhugePlant Soil Environ., 2025, 71(3):232-247 | DOI: 10.17221/35/2025-PSE Soil salinisation is a major constraint on food security and agricultural development, and remains a critical concern in the agricultural sector. In this study, we examined the effects of three straw return methods – straw mulching, straw burial, and a combination of straw mulching and burial – along with inorganic amendments (CaSiO3 and MgSO4) on maize growth, soil organic matter, bulk density, salinity, and the contents of individual salt base ions. A 120-day planting experiment was conducted using soil columns and included maize cultivation under irrigation and drenching conditions. The combined treatments (straw return with Ca-Mg application) were more effective in reducing salinity and improving soil properties than straw return alone. Na+, K+, Cl–, and HCO3 contents, as well as soil bulk density, decreased by 45.99–48.43, 28.07–28.36, 20.91–24.17, 18.93–21.03, and 7.64–8.40%, respectively. Regarding crop growth promotion, compared with the single treatment, the combined application of straw return with Ca-Mg (PI, SPI) resulted in a 6.46–8.30% increase in superoxide dismutase activity, an 8.66–10.83% reduction in malondialdehyde content, a 12.71–22.70% increase in total root length, a 13.41–24.14% increase in root surface area, and a 12.46–19.02% increase in root volume. Taken together, integrating straw return with a calcium-magnesium mixture represents a promising strategy for improving the quality of coastal saline soils. |
Soil organic matter quality ofvariously managed agricultural soil inthe Czech Republic evaluated using DRIFT spectroscopyOriginal PaperLenka Pavl, Ji Balk, Simona Prochzkov, Petra Vokurkov, Ivana Galukov, Ondej SedlSoil & Water Res., 2023, 18(4):281-291 | DOI: 10.17221/89/2023-SWR This study focuses onthe effect ofagricultural soil management onsoil organic matter (SOM) composition. The addition ofmanure and crop residues was tested under different pedoclimatic conditions. The quality ofSOM was assessed using diffuse reflectance infrared spectroscopy. The following parameters were calculated from the spectra: sum ofaliphatic bands (ΣAL), aromatic bands atwave numbers 1 620 and 1 520cm–1 (AR1620and AR1520), potential wettability (PWI), organic matter quality (OMQ), and decomposability (DI) indexes. The addition ofmanure orcrop residues may not cause fundamental changes inthe qualitative composition ofSOM. Rather, pedoclimatic conditions determine which components are fixed inthe soil onalong-term scale. Adominant effect ofsoil type was found inthe distribution ofall spectral parameters studied using main effect ANOVA. The main differences between the soil types concern the aromatic, oxygen and nitrogen groups contained inthe SOM. Chernozems are soils with higher OMQ andDI, whereas Cambisols are soils with low OMQ and DI and the highest PWI. The stabilisation ofSOM insoils can thus bebased onthe biochemical persistence oforganic molecules, their specific affinity for minerals and the formation ofaggregates that protect enclosed SOM. |
The forest land tax systems in Slovakia and PortugalOriginal PaperKlra Blikov, Natacha Jesus-Silva, Nomia Bessa Vilela, Michaela Koren Hillayov, Jaroslav lkaJ. For. Sci., 2023, 69(10):427-437 | DOI: 10.17221/51/2023-JFS Forests cover almost one half ofEuropean land. Therefore, land taxes, including taxes from forests, are essential for amunicipality's income. The land tax system isimplemented ondifferent levels, mainly nationally and locally. Therefore, many land tax features are settled byfederal law, and others differ according tothe local tax administrators.The objective ofthe paper istocompare the current laws and principles and the implementation process offorest land inSlovakia and Portugal. Wehave selected countries from different geographical areas ofEurope. Even though the forest compositions and forest ownership differ, weaimed toidentify whether the forest land tax systems can besimilar. Weanalysed the legislation and strategic documents onthe national level that helped ustodescribe the land tax system and its general features (e.g.taxpayer, tax rate, tax base, exemption options, tax period, orpenalties). Inboth countries, the national tax law governs the tax implementation and settles any basic processes related totax collection. The municipalities have the right torevise both the tax rates and exemptions. The results also show that forest owners inSlovakia have more options for tax exemptions than inPortugal. |
An update about beneficial effects ofmedicinal plants inaquaculture: AreviewReviewF Dadras, J Velisek, E ZuskovaVet Med - Czech, 2023, 68(12):449-463 | DOI: 10.17221/96/2023-VETMED Aquaculture is an essential and growing component of agricultural and global ecosystems worldwide. Aquaculture provides more than 25% of the total aquatic food consumption by humans. The development of the aquaculture industry should be followed in successive industrial years, and therefore it is necessary to pay attention to the management and type of farming system that is compatible with the environment. The use of antibiotics for disease control has been criticised for their negative effects, including the emergence of antibiotic-resistant bacteria, the suppression of the immune system and the environment, and the accumulation of residue in aquatic tissues. The use of these products reduces the need for treatments, enhances the effect of vaccines, and, in turn, improves production indicators. Medicinal plants have increasingly been used in recent years as a disease control strategy in aquaculture, boosting the immune system of aquatic animals and helping to develop strong resistance to a wide range of pathogens. Therefore, this review aims to provide an overview of the recent evidence on the beneficial use of medicinal plants to promote growth and strengthen the immune system in farmed aquatic animals. |
Development of Douglas fir merchantable stem volume model in the conditions of the Czech RepublicOriginal PaperRadoslav Hlavica, Zdenk AdamecJ. For. Sci., 2023, 69(12):515-524 | DOI: 10.17221/92/2023-JFS A precise merchantable stem volume model of Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] is missing in the Czech Republic. The aim of this study was to fit a new model through the reparametrization of volume equations (used in the Czech Republic or in other countries). We tested four volume equations (two from the Czech Republic, one from France and one from British Columbia) in the form of a nonlinear least squares model (NLS), weighted least squares model (WLS), and nonlinear mixed effects model (NLME). In all the tested models, the diameter at breast height of a tree and the total height of a tree were used as independent variables. Models were fitted on a dataset of 185 felled sample trees from eleven research areas with ages between 19–113 years. We have found that the model according to Omule et al. (1987) fits the merchantable stem volume as the best in the version of WLS model. Median value of the relative error of the final model was only –0.53%, which is less than the errors of models which are still used in the Czech Republic today. |
Hyperspectral analysis of the content of the alkali-hydrolysed nitrogen in the soil of a millet fieldOriginal PaperTingyu Zhu, Zhiqiang Wang, Zilin Zhang, Xiuhan He, Gangao Li, Zongbao Huang, Lili Guo, Zhiwei Li, Huiling DuPlant Soil Environ., 2023, 69(12):596-607 | DOI: 10.17221/421/2023-PSE Hyperspectral imaging technology has emerged as a prominent research area for quantitatively estimating soil nutrient content owing to its non-destructive, rapid, and convenient features. Our work collected the data from soil samples using the hyperspectrometer. Then, the data were processed. The competitive adaptive reweighted sampling (CARS) algorithm reduced the original 148 bands to 13, which accounted for 8.8% of the total bands. These selected bands possess a certain level of interpretability. Based on the modelling results, it can be concluded that the prediction model constructed by the least squares support vector machine (LSSVM) exhibited the highest accuracy. The coefficient determination, root mean square error, and ratio performance deviation were 0.8295, 2.95, and 2.42, respectively. These findings can provide theoretical support for the application of hyperspectral technology in detecting the content of the AHN in soil. Moreover, they can also serve as a reference for the rapid detection of other soil components. |
