Object - soil processes in podzolized soils under the influence of domestication by phytoameliorative actions. Purpose - the installation of influence of phytoameliorative actions of domestication of podzolized soils on the indexes of soil fertility, harvest and quality of grain of crops in afteraction. Methods - field, laboratory, laboratory and analytical, computational and comparative, mathematical statistics. Theoretical results - the positive influence of domestication of podzolized soils by phytoameliorative actions on the acid-base balance was theoretically summarized and scientifically grounded. Domestication influences decreasing of acidity, increasing the calcium activity, optimization of lime potential. It was proved that the cultivation of phytoameliorative crops with the help of their biopotential influences positively on the agrophysical indexes of podzolized soils, firstly, on the structural-aggregate composition water stability of structural aggregates, density and porosity. It was found that root systems of phytoameliorants influence the processes of structure formation in lower layers of soils. It was fixed that there is a tendency of humus content increasing in podzolized heavy loam chornozem after three years of phytoamelioration. Cultivation of alfalfa, sainfoin, lupine and soy increases the level of nitrogen from low to medium. Practical results - lie in improvement and scientific grounding of recommendations for choosing and usage of phytoameliorative crops, which are based on the discovery of their differential influence on fertility and productivity of podzolized soils. It was found, that phytodomestication of podzolized chornozem provided increasing of harvest and production quality of crops in afteraction. Results of research became a part of a monograph "Bases of soils' fertility management"; recommendations "Technological aspects of phytodomestication of floodplain soils". Novelty - at first time complex valuation of straight phytoameliorative action (without plowing) of alfalfa, sainfoin, lupine, soy, mustard and Sudanese grass on the physical-chemical, agrophysical and agrochemical indexes of podzolized soils was described; the regularity of changes of fertility indexes of podzolized soils was determined after their domestication with phytoameliorative actions; the most effective phytoameliorative crops for improvement of physical-chemical (alfalfa, sainfoin), agrophysical (alfalfa, sainfoin, mustard) and agrochemical (alfalfa, sainfoin, lupine, soy) of podzolized chornozem were identified; the positive influence of 3-year phytodomestication (perennial grasses) on the acid-base buffer indexes was found; it was found that the optimization of agrophysical parameters (structural-aggregate composition, compilation density) of podzolized chornozem is reached by 2-year cultivation of perennial grasses; high efficiency of phytodomestication afteraction on harvest and quality of crops (corn, barley, soy). Degree of application - the main results of studies were implemented on the lands of PPE "Panasenko O. V.", v. Kostiv, Valkivskiy district, Kharkiv region in 2014-2016 on the area of 20 hа. Materials of thesis were used in study process of master degree in KhNAU named after V. V. Dokuchaev for "Agronomy" speciality while teaching discipline "Soils' guarding and reproduction of their fertility". The field is agriculture.
