Zuza V. Soil conservation efficiency of anti-erosion equipped agrolandscape of Donetsk Northern Steppe

Object - formation processes of soil protection efficiency of different ways of tillage and crop yields by systematically applying them within anti-erosion equipped agrolandscape. Purpose - to establish the soil protection effectiveness of anti-erosion equipped agrolandscape and ways of primary tillage for crops. Methods - field and laboratory analyzes, methods of mathematical statistics. Theoretical results - a theoretical substantiation of functioning soil erosional complexes in Northern Donetsk Steppe and solve the problem of minimization of erosion on the basis of principles of agrolandscape agriculture in contour-reclamation area organization. It promotes better conditions for crop production in interstrip space. The regularities of the dynamics of soil parameters in conditions of anti-erosion complex, functioning within the soil protection, well-equipped agrolandscape. Is defined the effect on soil properties and soil regimes of different technologies of crop production. Practical results - the results are recommended for use in the development of measures to improve the anti-erosion stability of sloped soils, as well as the development of projects of land area equipped and design of soil conservation crop rotations. Obtained results allow to ascertain the long-term effect of forest strip and nonmoldboard cultivation, as most adapted to such territories. They are the basis for the concrete proposals, namely, recommendations for erosion control territory arrangement and improve soil fertility. Novelty - established that anti-erosion equipped agrolandscape, especially on the background of nonmoldboard cultivation in the forest strips system is able to maintain the optimal physico-chemical properties of the soil and its water-temperature regime. For the first time for the conditions of Northern Donetsk Steppe was proved ecological, economic and energy efficiency of nonmoldboard cultivation on crop yields. As well as was set the effective agronomic action of the forest strips system. Was set the regularities of deflation on the elements of the slope with different soil properties and different microclimatic characteristics in inter-strip space. Degree of application - results was tested in experimental farming "Donetskoye" of National Scientific Center "Institute for Soil Science and Agrochemistry research named after O.N. Sokolovskiy" on the area of 8 hectares. The field is agriculture.
