Properties Of Soil

The article presents the research materials of agrochemical properties of soil land use in the agricultural production co-operative ”Kolos”, Oktyabrsky district of the Volgograd region. The studied agroforestry landscape is located on the left bank of the Tsimlyansk reservoir, in the watershed of the Myshkov River. The territory of the farm is typical for the light chestnut sub -- zone of soils in the South of the Volgograd region. The results of the research are data on agrochemical properties of soils, their analysis and relative assessment, as well as proposals for improving fertility. The analysis of soil samples was carried out in accordance with the guidelines for the comprehensive monitoring of soil fertility of agricultural land. The soil sample was taken from an area of 40 hectares and is a mixed sample composed of 20 individual samples taken from the depth of the arable layer (0 -- 0.30 m). The total area of the surveyed arable land is 13.3 thousand hectares. Under laboratory conditions, chemical analyses were carried out and such parameters of soil fertility as humus content, content of macronutrients (NPK), content of water-bearing salts, soil granulometric composition, pH index were determined. Laboratory data are summarized in the table. The analysis of experimental data revealed the ranges of the studied parameters and identified four groups of relative soil fertility: fields with high, medium, low and very low fertility. The grouping of fields based on the account of soil fertility will allow using more differentiated and effective application of the system of measures aimed at increasing the yield and preserving soil fertility.

In OOO “Dubovitskoe” which was organized in 2006 as investment project of the AO “Shchelkovo Agrokhim” for 2010 – 2012 three advanced crop rotations have been developed. Before their introduction the grain crops fraction in the cropping system was 62%, then it fell to 49%. At the same time the portion of raw crops increased from 15 to 20%, legumes from 6 to 8%, others (buckwheat, grain maize, etc.) - up to 23%. As of 2017, the crops of leguminous crops have increased noteworthily. There are two predominant soil types here heavy clay loam podzolized chernozem (6615 ha) and grey forest soil (856 ha). Weighted average indicators (as of 2017): humus content in the soils of arable land is 5, 34%; acidity pH is 4.92; labile phosphorus - 111.8 mg / kg soil; exchange potassium - 144 mg / kg soil. The coefficient of the soil fertility in the enterprise (weighted average) is 0.66. This means that maintaining and increasing the soil fertility for arable land of the enterprise is critical task. As a result of the research, it has been established that the technologies introduced in the crop vegetation management (CVS) in the crop rotation conditions ensure high productivity of cultivated crops and stability of humus content in soils as an energy basis and a guarantor of increasing fertility. The indicators of the labile phosphorus Р205 and exchange potassium К20 in the soils depending on the crop rotation vary from a certain decrease to expressed steady growth. Therefore it is necessary to specify seeding rates based on actual data. Sustainable soil acidification in the crop rotations under crop cultivation in OOO “Dubovitskoe” it is the result of the acid feterlizers high rates application, during studying period did not carried out required agromelioration with calcium contenting elements.

Purpose: to establish the basic principles of the organization of reclamed agricultural landscapes and to substantiate the use of the agricultural landscape approach in the organization of the territory. Materials and Methods. When preparing this article, the materials of Russian scientists dealing with the issues of soil fertility conservation and ecological sustainability of reclaimed agricultural landscapes were considered. The methods used were analysis, generalization, synthesis and other methods of working with literary sources on this issue. Results. In performing the work, the main principles and indicators were determined, such as productivity, sustainability, the rule of transforming measures for the natural environment, optimization of the agricultural landscape, authenticity, principles of the formation of reclaimed agricultural landscapes, the complexity of the reclamation impact, the required diversity, the uniqueness of the reclamation impact. The basic requirements for the preservation of soil fertility of reclaimed irrigated agricultural landscape have been established. It was found that to maintain ecological balance within the irrigated agricultural landscape, it is necessary to adhere to the indicators of the reclamation load of the natural environment. The limits of agricultural lands saturation in reclaimed agricultural landscapes for various agro-climatic zones have been substantiated and recommended. Conclusions. It has been determined that the coefficient of reclamation loading of irrigated lands, showing the maximum share of irrigated lands that can be irrigated in a particular climatic zone, varies from 0.3 in the forest-steppe zone to 0.60–0.85 in the semi-desert and desert zone. This suggests that with an increase in moisture supply, this indicator decreases, the recommended amount of agricultural land in various agroclimatic zones varies from 30 to 87 %, while the area of arable land should not exceed 20–25 % in a very dry zone, and with an increase in moisture supply, it can increase up to 80 % in the semi-arid zone. The amount of irrigated land in the reclaimed agricultural landscape should not exceed 18–20 %. Irrigated meadows and pastures should account for 1–2 to 5–6 % of the area.

In experiments carried out on ordinary and leached chernozem, the effect of minimizing the methods of basic tillage and biologization on the fertility of these soils was analyzed. The studies were carried out in stationary and short-term experiments from 1984 to 2017. The effect of various methods and depths of the main tillage, autumn tillage systems, and fertilizers (mineral and organic) on the agrophysical, biological and agrochemical indicators of chernozem was studied. Refusal to carry out farewell processing in grain cultivating crop rotation leads to an increase in the differentiation of the arable layer, a decrease in the fertility of its lower part. The use of annual tillage in the crop rotation resulted in a decrease in the humus content in the soil layer of 0–40 cm by 0.17% (after fertilizers application) and by 0.22% (without fertilizers) compared to the dump processing by 20–22 cm. Organic fertilizers in a complex with minerals during farewell processing promotes an increase in the content of humus in comparison with the surface distribution during surface mulch tillage. A decrease in soil fertility and yield of cultivated crops without dump processing is proved.

The article presents the results of the agroecological composition of soils for different agricultural uses. Under modern conditions of increasing intensification of agricultural production, the agroecological condition of soils is deteriorating, which increases the risk of obtaining low–quality products. Along with this, there are various problems, such as loss of soil fertility, increased erosion, groundwater pollution and environmental pollution in general. Therefore, there is a need for constant monitoring of agroecological indicators of the soil in the conditions of intensive agriculture and horticulture. The great importance is the problem of finding reserves to increase soil fertility and improve their agroecological condition. Therefore, regular testing of soil nutrients and factors that have a major impact on their availability are extremely important to achieve sustainable levels of crop and fruit production. The main purpose of the research was to study and analyze agricultural lands: arable land and perennial plantations and the main agrochemical indicators of the soil of the central part of Vinnytsia region during intensive agriculture and horticulture. The object of research is the soils of agricultural lands used under intensive horticulture and crop production. The subject of research is the agroecological indicators of soil. The research was carried out in the farm of Agro–Etalon LLC in the village of Vasylivka, Tyvriv district. The soils of agricultural lands used under orchards (apple orchard) and agricultural crops (wheat after sunflower predecessor) were studied for comparison. According to the results of soil analysis, it was found that the highest difference in the studied indicators was found in the exchangeable potassium (К2О), mobile phosphorus (Р2О5), which was observed more in the soils involved in horticulture compared to the soils of field crop rotations. Farm soils with different agricultural uses were characterized by lower humus content. The highest difference in the concentration of chemical metals was found for molybdenum (Mo) and cadmium (Cd), which were more in the soils used in horticulture.

This article discusses the patterns of geographical distribution of the enhanced vegetation index EVI within the Bryansk region (upper Dnieper basin, south-western Russia) in the spring months of 2010-2015. The factors of index distribution, based on agricultural land monitoring data in other regions, are described. The crucial role of abiotic (topography, soil) and biotic factors in the distribution of the EVI is shown. The generalized data of meteorological observations of 2010-2015 are presented; the effects of their high variability on the range of the EVI values and its geographical distribution are shown. Data on the differences in the EVI distribution in the spring months of 2010-2015 is presented, which are explained by the differing periods of phenological seasons, surface relief characteristics (flat and convex watersheds, drainage conditions), lithological composition and humus content in the upper horizons of arable soil. A qualitative relationship between spring changes in the EVI for arable land and the combination of edaphic factors of agro-landscape functioning is established and the mechanisms that ensure such differences are presented. The use of the EVI distribution patterns is justified in the years with different climatic conditions to identify arable lands with different surface topography and soil characteristics.

AbstractDespite the large number of scientific studies on the effects of antibiotics on soil microorganisms, little is known about the role played by soil organic matter (humus) in the interaction of antibiotics with microorganisms and plants, including the impacts on respiration and growth rate and the implications for nitrogen metabolism, which is an important factor in soil fertility The aim of this study was to analyze the effects of two widely used antibiotics, tetracycline and streptomycin, on microbiotic activity and plant growth in two soils with dissimilar organic carbon content, at the extremes of the fertility spectrum based on humus content. The study used humus-rich (Corg 5.4%) and humus-poor soils (Corg 1.5%) and measured basal respiration, substrate-induced respiration, nitric oxide emission, germination, and growth of white mustard 3 and 60 days after three progressively increasing doses of antibiotics were applied. Tetracycline was found to impair the ecological function of humus-rich soil by reducing denitrification and compromising soil microbial activity, while the effect of streptomycin on humus-poor soil was to reduce nitrification and soil fertility due to nitrogen escape. Both streptomycin and tetracycline increased the microbial biomass and suppressed the growth of white mustard seeds, which indicates an increase in the allelopathic activity of microorganisms in the soil conditions under the influence of antibiotics and their metabolites. Due to the low sorption of streptomycin in humus-poor soils, it poses a great danger to agricultural production, especially in areas of low fertility. In humus-rich soils, high concentrations of tetracycline caused numerous problems, including death of the crop plants. Thus, the effect of antibiotics as well as the more traditional soil pollutants, such as heavy metals, to a large extent, depends on the humus content of soils.

The lack of an up-to-date cartographic basis leads to uncontrolled land turnover, does not reflect their real state and use, thereby leading to the destruction and degradation of not only individual components of the agricultural landscape, but also entire natural systems. Agrolandscape is a complex ecological system that, under harsh conditions of consumption, loses its ability to self-repair and regulate for a very long time. And each of its components needs to be accounted for, monitored, and protected. Geoinformation monitoring ensures the sustainability of both individual components and the entire agricultural landscape, contributes to the formation of effective agriculture and land use, increases the productivity of land and prevents the development of degradation processes. Monitoring of the territory of the Kislovsky rural settlement of the Bykovsky district of the Volgograd region according to 2004 data does not reflect the actual state and order of use of agricultural land and forest resources. The boundaries and areas of dehumified land have changed, and within the boundaries of the forest fund, according to Roseyestr, there are land plots with cadastral numbers ZU 34:02:010001:185, ZU 34:02:010001:104, ZU 34:02:010001:100, with an area of 2.7 hectares each for agricultural production. The area of forest areas has decreased from 576 ha to 484 ha or 16 %, the humus content in the soils is low—1.7 %, which is critical in the agro-climatic conditions of the Volgograd region. The location of agricultural land plots within the boundaries of the forest fund lands contradicts the land legislation, violates the safety and integrity of forest stands, leads to degradation, desertification and destruction of the ecological framework.

Steep Slopes

 Water consumption and productivity of grasslands are closely related to the type and degree of protection from erosion of the agricultural landscape. One of the main indicators of the type of agricultural landscape is the slope of the slope, which determines the level of soil fertility and productivity of agricultural land. With an increase in the slope, especially on erosive types of agricultural landscape (>30), the thickness of the a+B horizons decreases by more than 3 times from 64 cm on the plakor (<10) to 20 cm on steep slopes (10-200). The humus content in the soil horizon a decreases from 4.69 to 1.97%, or 2.72% in absolute value. Over 35 years, the complex of anti-erosion techniques has increased the power of soil horizons A+B, depending on the type of agricultural landscape, by 1-6 cm, the content of humus-by 0.16 - 0.36%, NPK – by 9.1-30.0%: a larger increase corresponds to the erosive types of agricultural landscape (>30). Productivity and water consumption of pasture lands depend on the level of soil fertility, snowiness of winters, the degree of moisture in the growing season, and the growth dynamics of pasture grasses. In the average humidification years (2015,2016) on open types of agricultural landscape, the productivity of grasses was 1.23-3.14 t / ha, the coefficient of water consumption -675-1538 m3 / t, and under the influence of anti-erosion techniques, respectively-1.73-4.05 t/ha and 627-1242 m3/t. The difference in water consumption coefficients reaches 23.8% on steep slopes (10-200). In dry years with the previous snowy winter on open types of agricultural landscape, the coefficient of water consumption is 930-1500m3/t, under the influence of anti-erosion techniques-703-1169 m3/t, or less by 32.7-28.3%. In wet years, the water consumption coefficient takes the lowest values due to the high productivity of grasses (5.61-8.89 t/ha). The complex of anti-erosion agrotechnical and forest-reclamation techniques is created in accordance with the type of agricultural landscape: on slopes with a steepness of 0-50-forest strips and mulched crevices; 5-80-forest strips and shrubby scenes; >80 - protective forest stands on terraces.

We used discriminant analysis to identify the key soil properties that discriminate among 30 forest sites representing a floristic site-type fertility gradient. Thereafter we classified 24 sites on afforested arable land into forest site types using these discriminant functions. The most important soil properties of the E horizon separating different forest site types were pH and the densities of Ca, P, and silt. Using properties of soil from the 0–10 cm depth to represent the current level of site productivity, we classified all soils from afforested arable land into forest site types of high productivity. Among these soils, the most fertile were those with high clay and silt densities. Again, using properties of soil from the 30–40 cm depth to emulate the site productivity that prevailed before soil-formation processes and agricultural land use altered the upper soil horizon, we classified most of the soils from afforested arable land into forest site types of medium productivity. This implies that agricultural land use had increased the densities of basic elements at the 0–10 cm soil depth and, consequently, site productivity. The high productivity of former arable lands was attributed to their previous agricultural use and to the inherent properties of fine-grained soils.
