Tkachuk V. The аgroecological substantiation of methods of basic till of soil and systems of fertilizer under a potato in the conditions of radioactive pollution.

The thesis is devoted to solving the actual problem - the development of agroecological principles of potato production in soddy-podsolic loamy-sand soil in a radioactive contamination zone Polesie. The thesis established regularities of long-term systematic fertilizer application and tillage methods on water and its physical, physico-chemical and agrochemical parameters and the degree of contamination of its heavy metals and radionuclides. The structure of the relationship between agri-environmental parameters sod-serednopidzolystoho sandy soil, and quantitative and qualitative parameters of potato tubers. A resource ecologically safe technology of potato cultivation after winter rye, a feature which is replaced in the system of primary tillage conventional tillage to a depth of 20-22 cm disc cultivation tools to a depth of 10-12 cm on the background of an alternative system of fertilization, which includes the introduction of 20 t / ha manure + N30P30K45 + 3,0-3,5 t / ha of straw predecessor and 10-12 t / ha green manure legumes.
