Kozak V. Reproduction of the fertility of podzolized dark-grey soil under influencing of interrow keeping in apple-tree planting

Object - soil-forming processes in podzolized dark-grey light loamy soil under different systems of interrow keeping in apple-tree garden and their influence on productivity and quality of garden-stuffs. Purpose - development of the system of measures on saving and reproduction of the fertility of podzolized dark-grey soil for the receipt of stable harvests of garden-stuffs of apple-tree of high quality and complex study of influencing of the green manure system of interrow keeping in apple-tree garden on processes and properties of soil. Methods - the long-term field tests, laboratory-field, laboratory-analytical, mathematical and statistical tests and methods of economic evaluation. Novelty - first in the conditions of Right-bank Forest-steppe in the profile of podzolized dark-grey soil complex research of influencing of different systems of interrow keeping in apple-tree garden is conducted on the parameters of its properties and fertility, productivity of apple-tree and quality of garden-stuffs. Itis proved, that the green manure system of interrow keeping affects both maintenance, and on quality composition of organic matter of soil. It is shown, that speed of mineralization and humification intensity of fresh organic matter relies on C:N ratio, amount of nitrogen and alkaline-earth elements in biomasse of green manure plants. Influence of the green manure system of interrow keeping in apple-tree garden is set on water and nutrient modes, physical, and physical-chemical properties of soil. On the basis of ecological, economic and energy evaluation of different systems of interrow keeping in apple-tree garden the most effective system with the use of the sowing of white mustard is grounded. Results of researches - are employed in the practice of crop production and research activities. Branch - agricultural sciences.
