Dokumenty týkajúce sa regulácie hospodárenia v lesoch sa prakticky až dodnes považovali za materiály, týkajúce sa skoro výlučne len jednotlivých odborných rezortov. Na základe Vyhlášky Ministerstva financií SR č. 465/1991 ich možno efektívne využívať aj v rámci rezortov financií a spravodlivosti. Ďalšie významné medzirezortné využitie týchto dokumentov vyplýva zo Zákona č. 127/1994 o posudzovaní environmentálneho dopadu. Cieľom práce je demonštrovať proces posudzovania na konkrétnom príklade - ploche patriacej do lesného pozemkového fondu. Okrem máp, výsledkov pozorovania, slovných popisov a súborov numerických údajov, týkajúcich sa jednotlivých porastov, obsahujú tieto dokumenty aj kódované údaje, ktoré pre väčšinu užívateľov nie sú zrozumiteľné bez využitia dekódovacích kľúčov. A práve tieto posledné údaje majú pri vyhodnocovaní environmentálneho dopadu najvyššiu výpovednú hodnotu. Po nadobudnutí platnosti pripravovaného zákona (vyhlášky) o strate vlastníctva, vyplývajúcej z prohibitívnych a ďalších podmienok v lesnom hospodárstve v súvislosti s presadzovaním verejno-prospešného záujmu (Kundrík et al. 1999), významne vzrastie dôležitosť využitia finálnych dokumentov týkajúcich sa regulácie hospodárenia v lesoch SR.

This paper deals with transformation of pure even-aged forest stands to uneven-aged irregular stands on an example of the Klokočná Forest Range. The fully operational management system according to principles of shelterwood or selection systems has been executed here since 1993. An investigation of this transformation process started in 1999 and it is focused on the places with more distinct structural differences. On the basis of research analysis, it is possible to consider about the permanent uneven-aged forest stands in future here. But for successful achievement of this goal it is necessary to continue this transformation step by step for a long time. The transformation is still at the beginning and its result depends on the effort and the forest management goal and the priority of the particular forest functions.

Technological changes bring about economic growth. We are now at the beginning of the new phase of global economic development called new economy. The bearers of it are especially information technologies, biotechnology, material, energetic and cosmic technologies. There is reflected the influence of important integration factors as new technologies, high competitiveness (which becomes a necessity), new economic culture in the sphere of government, households and business.

Food safety is important due to new protection measurements applied in the growing world trade as much as the raise and continuity of life quality. In recent years, the countries have begun to face with important problems both in domestic consumption and exportation, because of the sensitivity of consumers on the safety of food products. Regarding this, in the dairy industry, which is an important sub sector of the food industry, the food safety issues has begun to gain importance in developing countries like the developed ones as a result of the world trade. Therefore the aim of this study can be stated as examining the food safety systems for dairy industry and comparing them withTurkey.

During the first part of July, 2006, a severe outbreak of disease on common snowberry shrubs, Symhoricarpos albus var. laevigata, was observed in some city ornamental parks and small gardens in Prague and its environs. Based on disease symptoms and pathogen characteristics both on leaves, shoots, fruits and in culture, it can be concluded that the outbreak of anthracnose on common snowberry was caused by Sphaceloma symphoricarpi Barus & Horsfall 1928. This is probably the first record of S. symphoricarpi in the Czech Republic. Of the surveyed Symphoricarpos species and varieties, i.e. S. albus var. albus, S. albus var. laevigata, S. orbiculatus, S. doorenbosii, and S. chenaultii, only S. albus var. laevigata was attacked by the pathogen. Common snowberry shrubs having semipendent branches appeared to be more susceptible than shrubs with upright ones. Disease symptoms and pathogen characteristics are described and illustrated. The analysis of meteorological data indicated that the outbreak of anthracnose of common snowberry might have been related with rainy and mild weather during May, and especially with a rainy period of 7 days at the end of May and beginning of June.

A wide array of antioxidative and anti-inflammatory substances derived from edible plants have been reported to possess chemopreventive and chemoprotective activities. Among the most extensively investigated and well-defined dietary chemopreventives is curcumin. Using the Ames test and in vivo micronucleus test, chemiluminescence test, blastic transformation test, and comet assay, we examined the antimutagenic effects of the chemically identified chemoprotective substance curcumin (diferuloylmethane) in the pure form on mutagenicity induced by three reference mutagens: aflatoxin B₁ (AFB₁), 2-amino-3-metylimidazo[4,5-f]quinoline (IQ), and N-nitroso-N-metylurea (MNU), and the effect of curcumin on the immunosuppression caused by these mutagens. Curcumin in the pure form showed a clear antimutagenic and immunomodulatory activities on mutagenicity and immunosuppression induced by reference mutagens.

The aim of study was to verify a possibility of adding boron to multi-nutrient soil tests: Mehlich 3, water (1:5) and 0.5M NH₄-acetate extraction. Thirty-six different soils from topsoils of agriculturally farmed field were used for the study. The basic set of 36 soils was doubled when the same soil samples with gypsum addition at an equivalent dose 2 t Ca/ha were used. The closest correspondence between B in soil (n = 72) and B in plant was found out by the NH₄-acetate soil test. This test proved its good universality and independence on a radical intervention in soil chemistry by gypsum treatment. It responded to an increase in B-availability to plants after gypsum treatment of soil. The adjustment of NH₄-acetate boron by the percentage difference between the actual and the desired pH of soil improved the closeness of the correlation. Although the H₂O soil test showed its lower universality, it is assumed to use the H₂O soil test for prediction of B-status in soil when the history of previous fertilisation of the field will be known. The Mehlich 3 soil test did not prove to be suitable for diagnostics of B-status in soil.

The aim of this study was to investigate an association between aggressiveness and high level of feeding in a half-open feedlot production system. An experiment was conducted on 72 head of beef cattle of different breeds. The animals were at about 10 months of age. Medium quality silage was offered ad libitum and supplemented with high (HE) and low level (LE) of barley (2.5 and 1.5 kg/day/head, respectively) and supplemented without (nil) or with (+) extracted soybean meal (0.45 kg/day/head). Several types of animal behaviour were observed such as those parameters that are categorized to be main aggressive behaviours, butting, being butted, mounting and being mounted. Significant differences (P < 0.05) were found in butting, being butted behaviours between HE and LE treatment groups. Mounting and being mounted behaviours were significantly different (P < 0.05) in steers and heifers and between the seasons as well. Steers performed more incidents of mounting behaviour than heifers and it was the same for spring, during which animals had more mounting behaviours. It was concluded that there was a close relationship between high-energy diets and aggressive behaviour, which necessitates some management measures to be taken in order to ensure better animal welfare and beef production.

The effect of dietary supplementation of selenium in an organic form on performance, carcass traits and selenium content in tissues of broiler cockerels Ross 308 was studied. The soya-wheat-maize diet contained 50 mg vitamin E/kg. The experiment was conducted on 810 straight-run broiler cockerels randomly divided into 3 groups: group I - control, without selenium supplement; experimental group: II - 0.3 mg Se/kg, Se-enriched yeast was applied as a Se source; III - 0.3 mg Se/kg, Se-enriched alga Chlorella as a Se source. The broiler chickens were slaughtered at 42 days of age. In performance traits higher (P ≤ 0.05) live weight of broiler chickens was recorded in the experimental groups (II - 2 430.6 g and III - 2 425.2 g). There were no significant differences between the groups in feed conversion and mortality. Se-enriched alga had the best feed conversion, and selenium supplementation slightly increased mortality in both experimental groups. No significant differences between the groups were found out in carcass traits and dressing percentage. The content of selenium in breast and thigh muscle, feathers and excrements increased (P ≤ 0.05) in both experimental groups compared to the control group. Higher values in breast and thigh muscle and in feathers were measured in the group supplemented with selenium from Se-enriched yeast, also in comparison with the group supplemented with selenium from Se-enriched alga Chlorella. The broiler chickens receiving Chlorella had a higher (P ≤ 0.05) selenium content in excrements compared to the group with Se-enriched yeast. The selenium concentration in liver was higher (P ≤ 0.05) in both experimental groups compared to the control. The supplement of selenium from Se-yeast and Chlorella in the diet for broiler chickens increased the microelement concentration in muscle.

Soils of reclaimed dumpsites after coal mining are considered as typical anthropogenic soils. These soils are at the beginning of their development and have certain specific characteristics. The aim of this study was to describe a soil survey performed on anthropogenic soils of a reclaimed dumpsite, to analyse spatial variability of selected properties using geostatistical methods, and to evaluate the development of reclaimed dumpsite soils. It has been shown that geostatistical methods are suitable for a description of anthropogenic soil properties and their variability. However, characterization of soil properties on the border between areas with different types of reclamation can be difficult due to sharp discontinual transitions caused by human activity. Properties of these soils vary profoundly greatly dependent on the properties of the soil substrate and the type of reclamation. The average content of organic carbon in the topsoil (0-20 cm) was 1.92% on the area covered with a layer of natural topsoil and 0.92% on the area covered by a layer of loess. An initial A horizon can develop even in 10 years under favourable conditions.

The effects of different levels of bud loading on the yield and some leaf and fruit characteristics in Hayward cultivar (A. deliciosa) in the province of Ordu, Turkey were examined during two growing seasons in 2000-2001. Six years old kiwifruit vines were pruned to carry the loads of 120, 180, 240 or 300 buds/vine on the canes with 12 buds. The study determined probable total leaf area (PTLA), probable total leaf number (PTLN), probable total leaf weight (PTLW) and yield per vine. Mean fruit weight (MFW) and soluble solid contents (SSC, %) of fruits were expressed. In addition, unit leaf area/100 g fruit weight (ULA/FW) was calculated. Leaf characteristics were examined in 3 periods of the growing season. Correlations between yield, leaf and fruit characteristics and treatments were determined. The result of the experiment, namely mean leaf area (MLA), mean leaf weight (MLW), PTLA, PTLN, PTLW ranged between 185.51-194.17 cm², 7.98-8.67 g, 21.047-58.61 m²/vine, 1,129.6-3,035.3 number/vine, 9.04-25.68 kg/vine, respectively. The mean yields of vines loaded with 120 and 300 buds were 34.84 and 100.96 kg/vine (12.19 and 35.34 ton/ha), respectively. Mean leaf area and mean leaf weight increased with increasing levels of bud loading, whereas MFW and ULA/FW decreased. There was a negative relationship between MFW, SSC and yield, and a positive relationship between MLA, PTLA and yield. ULA/FW ratio was between 581.88-611.54 cm² according to the bud loading level. Fruit size diminished as a consequence of dense canopies in both levels of bud loading (120 and 300 buds/vine). Unit leaf area per fruit weight ranged between 581.88-611.54 cm²/100 g, with respect to the bud loading applications. Increasing levels of bud loading resulted in reduced ULA/FW ratio and affected yield and some leaf and fruit characteristics.

The haematological parameters of the common pheasant (Phasianus colchicus), the dynamics of changes in blood count parameters with regard to the season of the year and reproduction status, and the effects of sex and body condition on the haematological parameters of blood were studied. In total, 574 blood samples were collected. The samples were collected from pheasants from the age of 6 months, prior to the laying period, and after the laying period. Packed cell volume and haemoglobin concentration significantly increased in males during the period of growth and decreased during the period of reproductive activity. Significantly higher values were detected in males compared to females in erythrocyte count, packed cell volume, haemoglobin concentration and in mean corpuscular haemoglobin concentration. A statistically significant positive relationship was detected between weight and the values of most of the parameters related to red blood cells.

Sera of 413 dogs and 286 cats from the CzechRepublicwere tested for antibodies to Toxoplasma gondii by the indirect fluorescent antibody test. The IgM antibodies to T. gondii were found in 10 (2.4%) dogs and 8 (2.8%) cats; IgG antibodies were found in 107 (25.9%) dogs and 126 (44.1%) cats. Of the dogs, the most exposed group were pet dogs, followed by police dogs; no antibodies were found in laboratory dogs. No statistically significant differences in prevalence were observed between clinically healthy (n = 115) and diseased pet dogs (n = 80); compare 0.87% and 1.25% for IgM, and 33.9% and 33.75% for IgG, respectively. Although T. gondii is a common parasite in domestic cats and dogs, the clinical importance is low.

Forestreclamation of spoil banks in mining areas in the North-West of the country started in the second half of the last century. Nowadays forest stands growing on anthropogenic substrates which are still unlike to forest soils, are getting in the phase of possible natural and/or artificial regeneration. The basic characteristics of substrate in the area and ecological attitude of used tree species are driving variables for successful regenerations. The study summarizes the vitality and growth of selected species on anthropogenic substrates in the area with the recommendations of key tree species used for forest reclamation. The results show the best adaptation to anthropogenic substrates for black alder and maple.

The paper analyzes the development and the prospects of organic farming in the Czech Republic with particular emphasis on organic beef farming. The background information on organic farming in the Czech Republic regarding the structure of land use, legislation and support payments as well as a short description of the market for organic beef is provided. An analysis of the economic performance and of the impact of payments on the economic situation of organic beef farms follows. Grazing livestock farms, mostly cow-calf systems, are the most widespread farm type in the Czech Republic. Five typical farm models were set up with the aim of giving an overview of the diversity of organic beef production systems. The results indicate that organic beef farming is in most cases economically viable. Nevertheless, organic farming payments, as well as other payments, account for a high share of economic success, so that it can be stated that organic grazing livestock farms are highly dependent on support payments.

The paper deals with identification of some forms of potential competitive advantage that can be applied by the Slovak agrarian enterprises after the accession to the EU. The capacity of the economies of scale is being analyzed, as well as the potential of the labor productivity growth, and input management in controlling of intensification process. The paper is targeted at verifying the extent of application of competitive advantages by agrarian enterprises, and identifying the reasons of obstacles that hinder their full utilization.

A total of 199 Phytophthora infestans isolates were obtained from leaves, tubers and fruits of infected crops of potato and tomato in different regions of the Czech Republic in 2003, 2004 and 2005. They were analysed for mating type using the conventional pairing assay and PCR markers; 107 isolates were of A1 and 92 of A2 mating type. No self-fertile isolate was found. Our study is the first report of the presence and distribution of the A2 mating type of P. infestans in the Czech Republic. The co-existence of the two mating types may enable the pathogen to reproduce sexually, thus enhancing the diversity of its population countrywide.

The priority of this study was to investigate how selenium influences toxicity of Cd, Zn, Cu and Pb when the metals appear in the hydroponic solution in pairs. As a model subject mustard seedlings (Sinapis alba L.) were used. Except phytotoxicity of individual metals and Se-metal combinations determined through photosynthetic pigments content (chlorophyll a, b, total carotenoids) also metal accumulation in the roots and shoots was determined by the AAS method. Se in all metal combinations reduced the unfavourable effect of other metals tested for chlorophylls content, however, for carotenoids primarily the opposite effect occurred. For metal accumulation in the roots and shoots it was confirmed that Se stimulated only Cd (about 24%) and slightly Cu (about 9%) accumulation in the roots, while in the shoots there was inhibited accumulation of all metals tested. The strongest inhibition was observed in Pb accumulation (84.9%). This fact indicates that Se generates some barriers for metal transfer from the roots to the underground plant parts. In contrast, Cu, Zn, Pb and Cd increased Se accumulation in the roots in the range of 4 (in combination with Cu) to 68% (in combination with Cd) and in the shoots in the range of 11 (in combination with Pb and Zn) to 44% (in combination with Cd). In the shoots only Cu inhibited Se accumulation (about 67%).

Effects of the year, previous crop and control of leaf diseases on grain yield, test weight, protein and starch content, Fusarium head blight (FHB) and deoxynivalenol (DON) content in grain were investigated in four spring barley varieties. The trials were set up in 2001-2004 at Kroměříž (235 m above sea level, average annual temperature 8.7°C, annual precipitation sum 599 mm) in a five-course crop rotation, where spring barley followed the previous crops sugar beet, winter wheat, maize, and oilseed rape. The experimental years differed a lot in temperature and precipitation. The years 2001 and 2002 were dry and warm and grain yield was much lower as compared to that in the following years even though the other growing conditions were identical. The most stable quality parameters were obtained after the previous crop sugar beet. The average value of test weight was 661 g/l(ranging from 629 to 685 g/l), protein content 11.2% (10.3-11.7%) and starch content 61.5% (58.9-64.9%). Grain yield averaged 6.67 t/ha. Test weight after maize was on average 658 g/l(619-692 g/l), protein content 11.5% (10.1-12.4%), starch content 60.7% (59.2-63.8%), and grain yield 6.24 t/ha. Test weight and starch content were lower and protein content higher after oilseed rape and winter wheat. A higher FHB incidence and DON content were found after the previous crop maize. In 2001 and 2002 with strong water deficit during the growing seasons, more grains infected by Fusarium spp. were detected and DON content was higher too. The increase was due to a short rainy period at heading of spring barley. Problems of variable conditions for growing malting varieties of spring barley and current possibilities of producing both good grain yields and quality are discussed.

This study was conducted to determine the effect of row spacing (40, 60 and 80 cm) on forage dry matter (DM) yield and quality of four hybrids grown in the years 2001 and 2002. The highest DM yield was obtained from the Arifiye (24.1 and 22.4 t/ha) while the lowest DM yield was obtained from Pioneer 3163 (19.9 and 19.8 t/ha) in the years 2001 and 2002, respectively. As row spacing increased, DM yield as an average of two years decreased from 27.2 to 16.6 t/ha. No differences were found among row spacing for DM content, harvest index (HI) and ear content. As row spacing increased, whole-plant acid detergent fiber (ADF) and neutral detergent fiber (NDF) content increased from 214 to 227 g/kg and from 420 to 451 g/kg during the year 2001, respectively. However, ADF content decreased from 281 to 267 g/kg and NDF contents decreased from 530 to 515 g/kg with increasing row spacing during the year 2002. In this study, hybrids showed distinct differences for crude protein, ADF and NDF contents in both years. Forage quality parameter including ADF and NDF of Pioneer 3163, TTM 8119 and Karadeniz Yildizi were higher than Arifiye hybrid.

A total of 1 200 broiler breeder eggs were collected from a commercial flock at the hen age of 37 weeks and divided into storage treatments of 5 and 15 days. Prior to storage, the eggs were further divided into pre-storage incubation (PRESI) 0 (control), 4 and 8 h treatments. Eggs in the 4 and 8 h PRESI treatment were incubated at a standard dry-bulb temperature of 38.0°C. All eggs were weighed prior to and after storage, then incubated in a commercial setter and hatcher for 21 days. After the incubation, all unhatched eggs were opened to determine fertility, hatchability and embryonic death. The 4 and 8 h PRESI treatment significantly decreased hatchability results of long-term stored eggs compared to non-heated eggs. Hatchability results of eggs stored for 5 days were significantly better compared to eggs stored for 15 days. Subsequent growth performance of progeny was not significantly affected except for the main effect of egg storage on feed conversion. There were significant PRESI × egg storage interactions for apparent fertility, hatchability of total and fertile eggs and embryonic mortality. It was concluded that the PRESI treatment did not have a detrimental effect on the hatchability of broiler breeder eggs stored for 5 days and it might even increase hatchability while it had a detrimental effect on the hatchability of broiler breeder eggs stored for 15 days.

This research was carried out to determine the effect of Jerusalem artichoke (JA) with or without 5, 10% vetch (V) supplementation on performance, egg quality characteristics and egg cholesterol content. In the study, seventy-five 25 weeks-old commercial white laying hens were randomly divided into one control and 4 treatment groups each containing 15 hens. Control group was fed basal diet without JA or V. Treatment group 1, 2, 3 and 4 were fed diets containing 5% V, 5% JA, 5% JA + 5% V and 10% JA + 10% V, respectively. The feeding period lasted 16 weeks. In the study, it was determined that dried-ground JA contained dry matter, crude protein, ether extract, crude fibre, crude ash, inulin and metabolizable energy (ME) at the level of 93.30, 10.02, 0.36, 5.64, 9.05, 15.80% and 3 060 kcal/kg, respectively. At the end of the study, live weight was lower by 4.36-10.09% in the treatment group 10% JA + 10% V compared with the other groups, but feed efficiency was improved in this group. There were statistically significant differences between the groups in egg quality characteristics (P < 0.05, P < 0.001). Egg production was not affected by supplementation of 5, 10% JA with or without 5, 10% V supplementation. Egg yolk cholesterol and total cholesterol content were not different in the groups (P > 0.05). As a result, the addition of JA with or without V has no adverse effect on performance and egg quality in hens.

Putting together work operations minimizes the number of machine passes across the plot, which helps to reduce negative soil compaction and to save fuels. However, the combination of working operations also reflects in the increased weight of machines, which - on the other hand - can result exactly in soil compaction. This is why the potential adverse phenomenon can be compensated by using tyres with a larger contact surface with the base. In the case of sowing root crops, some problems may appear with the application of these tyres as a certain part of the stand has been sown in their track. The paper brings an assessment of the possibility to use twin assembly tyres on the tractor model Fendt 822 and on the sowing drill model Monosem NG plus with 18 drilling mechanisms. Parameters to be assessed were soil compaction, and the development of plants sown inside and outside the tractor track. Although the degree of soil compaction was higher in the tractor track, the biological characteristic of plants including yield reached more favourable criteria of assessment. The situation paradoxically resulted from the creation of more favourable moisture conditions in the soil.

The objective of our study was to test amaranth grain or dried biomass in the diet for broiler chickens as a resource of protein replacing animal protein. Further, the effect of amaranth on broiler performance, carcass characteristics and meat quality were assessed in a feeding trial. The experimental groups of broilers were fed feed mixtures with crude amaranth grain (AC), heat processed amaranth grain (AP) or dried above-ground biomass (AB). Control groups (C) received the diet containing animal proteins. The results obtained in the experimental groups of broiler chickens can be compared to the control group in all the production indicators under investigation. On day 42 of the experiment, live weight (g) of female broilers ranged from 2 205.1 ± 152.5 (AP) to 2 254.0 ± 136.5 (C), and that of male broilers from 2 375.1 ± 233.0 (AC) to 2 506.0 ± 286.0 (C). Feed conversion ranged from 1.80 kg in control group of male broiler chickens to 1.91 kg in experimental group of male broilers (AB). Percentage yield in female broiler chickens ranged from 70.8 ± 1.74 (AB) to 72.4 ±3.34(AC) or 72.4 ± 1.98 (C), and in male broilers from 72.8 ±3.55(AP) to 75.1 ±2.44(AB). Our results showed that amaranth can fully replace meat-and-bone meals in the diets for broiler chickens.

The basic feature of an economic reform of the forestry in the Czech Republic after 1990 was separation of supervision in the state forests from operating performance. The Forests of the Czech Republic, state enterprise, was charged with management and supervision, hence economic activities of the subject are provided on the basis of contracts by entrepreneurial units called contractors in the forestry. The purpose of the paper is economic analysis of the Forests of the Czech Republic, state enterprise, in the period 1998-2002. The objective is the construction and testing of an elementary method of financial analysis as well as outline of financial situation and development of the chosen subject generally. The paper contributes to branch economy analysis, common in agriculture and wood-processing industry.

The article presents original results of research on the humus form dynamics in a semi-natural European beech stand in the National Natural Reserve Voděradské bučiny, in the area of Training Forest Enterprise at Kostelec nad Černými lesy (Czech University of Agriculture inPrague). The accumulation and soil chemical characteristics of particular humus forms were studied: dry matter amount, pH, soil adsorption and exchangeable acidity characteristics as well as plant available and total nutrient contents. The humus form samples were taken in four replications from the particular humus form layers (L, F, H, Ah), and the analyses were performed individually. Samplings were done in the parts of the stand with closed canopy, and they were compared with the state in gaps formed during natural and semi-natural forest regeneration (the stage of stand breaking up left to spontaneous development). The results confirmed marked changes in the quantity and quality of surface humus in the gaps. The amount of dry matter decreased by ca. 25% several years after canopy opening, especially in the H horizon, the pH, base content and base saturation increased, as well as the content of macronutrients (with the exception of total calcium). The results proved considerable changes in the humus forms during the natural and semi-natural forest cycles connected with the stand regeneration.

At the end of nineties, within the mountain forests of the Krušné hory Mts., in connection with an increased acid deposition, the symptoms (yellowing) started to be visible, characterizing magnesium deficiency in the assimilation organs, when Mg contents were laying under 300 mg/kg. In mineral soil the Mg content is mostly less than 10 mg/kg. Contents of other basic elements (Ca, K) were also very low. During four years yellowing symptoms of the spruce stands have developed in an extent area of more that 10,000 ha. Since 1999, preventive measures have been adopted to improve the nutrition status of the forest stands. Liquid magnesium fertilizers as MgNsol, Lamag Mg, MgSsol were applied during the period of 1999-2002. Since 2001, in semi-operational experiment, powder Mg fertilizer - Silvamix F4 - of higher Mg content (63.3% MgO) was applied. Application of liquid fertilizer MgNsol has helped to compensate the nitrogen deficiency in the stands of insufficient nutrition in this element. Comparing of different types of liquid fertilizers has confirmed, that the highest increase of magnesium in assimilation organs was find in combined application of MgNsol and MgSsol fertilizers. Application of 300 kg/ha Silvamix F4 has increased the magnesium content in the first needle year class in 73% in average, potassium in 33%, calcium in 16%, and phosphorus in 85%. Besides increased nutrient content in needles also improvement of the health and phosphorus in 85%. Besides increased nutrient content in needles also improvement of the health state, i.e. revitalization of the stands affected can be observed.

The primary goal of our analysis is to evaluate the effects of changes in the Slovak agriculture subsidy system on the selected farms located in different production areas between the years 2003 and 2004. Our comparative analysis divides the farms into two groups: The first group represents all those farms that operate in good farming conditions i.e. primarily the land is more productive (PA). The second group of farms operates in less favorable farming conditions (LFA). The regions differ from each other in terms of geographical position, location, production and climatic conditions, as well as the quality of land. We analyzed data of 119 farms.
