China Title: Micro plastics in soil ecosystem - A review of sources, fate, and ecological impact Abstract: In recent years, environmental experts and stakeholders have paid increased attention to the pollution of micro plastics in the soil. As persistent pollutants, micro plastics have a significant impact on the soil ecology, agricultural production, and the overall health of the ecological environment. Micro plastics can influence soil bio-physicochemical properties and the mobility of other contaminants in soil, with potentially significant implications on soil ecosystem functionality. Thus, functions including litter decomposition, soil aggregation or those related to nutrient cycling can be altered. Furthermore, micro plastics can influence soil biota at different trophic levels, and even threaten human health through food chains. Despite this potential negative interaction, there is limited research on micro plastics in the soil environment. The primary goals of this review are to summarise the sources, distribution characteristics, migration and degradation laws of micro plastics in the soil ecosystem, to summarise the combined effects of micro plastics and other pollutants in the soil ecosystem, to analyse the effects of micro plastics on soil physical and chemical properties, animals, plants, and microorganisms, and to reveal the effects of micro plastics on soil ecosystem and to according to the distribution characteristics of soil micro plastics, degradation, migration and ecological effects, propose pollution control measures. This current review will provide a comprehensive understanding of soil pollution by micro plastic and offer a scientific basis for the formulation of novel management practices that will protect and improve soils, and contribute to the sustainable development of the ecological environment and highlight important areas for future research.

G. Don by potassium and ascorbic acid treatments Abstract: Catharanthus roseus seedling was treated with different concentrations (1.5, 3.16, 15, and 30 mmol) and forms (K2SO4 and KNO3) of potassium (K+) via Hoagland's nutrient solution. Ascorbic acid (AsA) was sprayed twice (plant days 68 and 78) with different concentrations (750 and 1 500 mg/L) on the leaves. Vinblastine, vincristine, tryptophan contents, D4H and DAT genes expression, peroxidase activity, and H2O2 content of leaves were measured. Potassium in KNO3 form increased vinblastine (60%) and vincristine (50%), compared to 30% and 20% using K2SO4. Vinblastine and vincristine inhibit microtubule assembly and ultimately metaphase-arrested caused by the polymerisation. The genes expression was higher 3 times in KNO3 and 2.5 times in K2SO4 in excess of K+. Foliar application of 750 mg/L AsA led to an increase in vinblastine (20%) and vincristine (16%). Both concentrations of AsA had the same additional effect on the expression of D4H and DAT about 30% and 60%, respectively, compared to the control plant. Tryptophan decreased 2.5 times in excess of K+ and 35% due to the exterior of AsA. H2O2 decreased while peroxidase activity increased along with AsA treatment. A positive interaction existed between the K+ and AsA on the amount of vinblastine, vincristine, tryptophan, and gene expression.

The studied soil undergoing crop rotation systems were rice-rice-rice (SR) and baby corn-rice-mungbean (SB). Two main microcosm set-ups: anaerobic (SR-AN, SB-AN) and aerobic (SR-AE, SB-AE) conditions. Litter bags containing rice stems were inserted into the soil and recollected at different time points for chemical analysing and the gas sampling was collected to measure the CO2 and CH4 emissions. The results indicated that the total carbon (TC) decreased around 30%, and the TC removal in anaerobic was significantly higher than in aerobic conditions. The residue cellulose content varied in a range from 68.2% to 78.6%, while the hemicellulose content varied from 57.4% to 69.3% at day 50 after incorporation. There were no significant differences in the total nitrogen removal, cellulose, hemicellulose, and lignin contents among the microcosm set-ups. CO2 emission increased in all the microcosm set-ups with the treatments without rice straw (CTSR, CTSB) in both aerobic and anaerobic conditions. CH4 release in the SR-AN treatments did not differ significantly compared with the SB-AN treatments. This study confirmed that the decomposition of rice straw residues is faster in the anaerobic paddy soil condition compared to the aerobic crop rotation condition.

This study investigated the effects of soil NO3--N content and accumulation, eggplant yield, N leaching and balance response to biochar addition, including regular fertilisation and irrigation (W + F), biochar addition with regular fertilisation and irrigation (W + F + B), and biochar addition with 20% fertilisation and irrigation reduction (0.8W + 0.8F + B) treatments. Compared with W + F, W + F + B and 0.8W + 0.8F + B increased soil NO3--N content in 0-40 cm and soil NO3--N accumulation in 0-20 cm, and raised harvest index, N surplus and balance. Simultaneously, 0.8W + 0.8F + B compared to W + F enhanced N use efficiency and N partial factor productivity, conversely, it decreased N dry matter production efficiency, N surplus and balance. Stepwise regression analysis demonstrated that the effect of NO3--N leaching lasted in 60 cm under biochar addition in the first year, and lasted in 20 cm without biochar application in the next year. Altogether, biochar addition with 20% fertilisation and irrigation reduction is the most suitable management strategy to decrease N surplus and leaching, and maintain eggplant N uptake in a two-year cycle system on greenhouse vegetables in Mollisols.

We measured N2O flux dynamics in Hani peatland in a growing season with simulating warming and N addition for 12 years in the Changbai Mountains, Northeastern China, by using static chamber-gas chromatography. We hypothesised that warming and N addition would accelerate N2O emissions from the peatland. In a growing season, the peatland under natural conditions showed near-zero N2O fluxes and warming increased N2O emissions but N addition greatly increased N2O absorption compared with control. There was no interaction between warming and N addition on N2O fluxes. Pearson correlation analysis showed that water table depth was one of the main environmental factors affecting N2O fluxes and a positive relationship between them was observed. Our study suggests that the N2O source function in natural temperate peatlands maybe not be so significant as we expected before; warming can increase N2O emissions, but a high dose of N input may turn temperate peatlands to be strong sinks of N2O, and global change including warming and nitrogen deposition can alter N2O fluxes via its indirect effect on hydrology and vegetation in peatlands.

The effect of inoculation strain was evaluated under different soil conditions: with or without previously grown soybean and applied commercial inoculant. Molecular identification of inoculation strain and investigated rhizobial isolates, obtained from nodules representing inoculated treatments, was performed based on 16S rDNA and enterobacterial repetitive intergenic consensus (ERIC) sequencing. Inoculation strain showed a significant effect on the investigated parameters in both soils. Higher nodule occupancy (45% vs. 18%), nodule number (111% vs. 5%), nodule dry weight (49% vs. 9%), shoot length (15% vs. 7%), root length (31% vs. 13%), shoot dry weight (34% vs. 11%), shoot nitrogen content (27% vs. 2%), and nodule nitrogen content (9% vs. 5%) was detected in soil without previously grown soybean and applied commercial inoculant. Soil had a significant effect on the shoot, root and nodule nitrogen content, while interaction of experimental factors significantly altered dry weight and nitrogen content of shoots, roots and nodules, as well as number of nodules. Nodulation parameters were significantly related with shoot dry weight, shoot and nodule nitrogen content. Symbiotic performance of inoculation strains in the field could be improved through co-selection for their competitiveness and effectiveness.
