Soil Conservation Measures

The solution of preserving and restoring the soil fertility problem of agricultural lands in the process of economic activity is one of the main tasks in achieving global food security. Implementation of a complex of soil protection measures, as a rule, ensures the preservation and even growth of soil fertility. Therefore, the purpose of the article is to determine the economic efficiency of introducing soil protection measures in the use of agricultural land. For this purpose, the following tasks were set and solved: the analysis of the current state and trends of the land resources use in agriculture; to investigate the tendencies of carrying out measures on preservation of soil fertility and prevention of its degradation; to substantiate scientific and methodical estimation principles of economic efficiency of introduction of soil protection measures in the conditions of Ukraine. The following basic methods were used to solve the research objectives: monographic analysis – when developing scientific publications on environmentally friendly use of agricultural land; comparative and statistical analysis – in studying the dynamics of the structure of the land fund of Ukraine by main types of land and economic activity; system-structural analysis and grouping – in the study of the nature and content of ecological and economic consequences of soil degradation, as well as approaches to assessing the economic effectiveness of soil protection measures; economic analysis and calculation of relative indicators – to evaluate the economic efficiency of soil protection measures in the process of agricultural land use; abstract-logical method - for theoretical generalizations and conclusions formation, etc. Established that soil degradation is now one of the most important industrial and environmental issues, which is the main reason for the inability to achieve high rates of environmental and economic efficiency of land use in the future. It was also substantiated scientific and methodical approach to determining the economic efficiency of soil conservation measures in the current market conditions, which is based on the additional income that is received as a result of increase crop yields on protected lands. It is established that effective protection of soils from degradation is possible with the systematic implementation of soil protection measures complex, developed taking into account the specific natural and economic conditions of each region or agricultural enterprise. The priority directions of realization measures on land protection are given.

Analysis Of Dynamics

The main trends in changing the land use structure in the territory of the Klyazma River basin were de-scribed in the article. Using GIS technologies and remote sensing data the areas of land with different land use regimes in the studied territory were determined in the period from 2001 to 2019. The indices of LAI and FPAR phytoproductivity for the territory of the Klyazma basin as a whole, and for each basin included in it were determined. The analysis of the dynamics of changes occurring in the structure of land use is carried out. For the territory of Vladimir region, which is a part of the Klyazma River basin, an assessment of soil types distribution over occupied area was carried out. An integral indicator of soil fertility was calcu-lated on the basis of statistical data of agrochemical indicators. The fraction of fallow lands decreased by 2019 and it amounts 33.76% of the total area of the studied territory. The fraction of mixed forests increased from 38.48% in 2001 to 44.50% in 2019 due to the formation of fast-growing tree species shoots on fallow lands. The area of meadow vegetation for the period from 2015 to 2019 decreased by 3.5%, from 4 276 to 3 121 km2, due to agriculture degradation and a significant decrease in livestock grazing. The indicator of soil fertility for the Klyazma basin was 0.74, which is a high indicator. It is established that the most active decrease in the agricultural land area occurs in the central, north-western and western parts of the river basin.

Abstract. Land degradation resulting from improper land use and management is a major cause of declined productivity in the arid environment. The objectives of this study were to examine the effects of a sequence of land use changes, soil conservation measures, and the time since their implementation on the degradation of selected soil properties. The climate for the selected 105 km2 watershed varies from semi-arid sub-tropical to Mediterranean sub-humid. Land use changes were detected using aerial photographs acquired in 1953, 1978, and 2008. A total of 218 samples were collected from 40 sites in three different rainfall zones to represent different land use changes and different lengths of time since the construction of stone walls. Analyses of variance were used to test the differences between the sequences of land use changes (interchangeable sequences of forest, orchards, field crops, and range), the time since the implementation of soil conservation measures, and rainfall on the thickness of the A-horizon, soil organic carbon content, and texture. Soil organic carbon reacts actively with different combinations and sequences of land use changes. The time since stone walls were constructed showed significant impacts on soil organic carbon and the thickness of the surface horizon. The effects of changing the land use and whether the changes were associated with the construction of stone walls, varied according to the annual rainfall. The results help in understanding the effects of land use changes on land degradation processes and carbon sequestration potential and in formulating sound soil conservation plans.

The quality and quantity of agricultural production depend on the fertility of the soil type on which it is grown. Soil fertility is the result of the interaction of multiple mutually merged factors. Loss of soil fertility leads to soil degradation. Subsequently, it gradually becomes unfit for farming activity. Controlling the maintenance and enhancement of soil fertility is the guarantor of sustainable yields and population satisfaction with food resources, protecting land from degradation, and preserving biodiversity of ecosystems. The report examines the opportunities for restoration of the soil fertility of the agricultural lands of the Yambol Agro region. The aim is to analyze and propose for practice the most suitable methods of organic farming, with the application of which to preserve and improve the fertility of soils from the agricultural fund of the region. The proposed options are in line with the requirements of the European Union and the elements of the Common Agricultural Policy for Conservation of Soil Fertility. As a result of analysis and studies found that the preservation and maintenance of soil fertility in agricultural land in Yambol agroregion is recognized and priority policy of the departments of Agriculture and farmers. From soil fertility conservation methods, organic farmers in Yambol Agro region apply a comprehensive approach, focusing primarily on bio-fertilization, crop rotation and sequential soil treatment systems.
