Tymchuk I. Agroecological estimation of capsulated mineral fertilizers in conditions of the west of Ukraine

The dissertation work is dedicated to research of influence of the capsulated mineral fertilizers on agroecosystems. The analysis of the contamination ways of agroecosystem by fertilizers is conducted, the use of new types of the capsulated fertilizers are offered. The complex of laboratory agroecological research for establishment of influence of the new created types of fertilizers on pH and soil microflora, change of amount of nourishment elements and on kinetics of growth and development of plants are carried out. The complex of tests of the capsulated mineral fertilizers efficiency in the agroecosystems of the field cultures is conducted. The coefficient of use efficiency of different types of fertilizers is established for growing of potato, spring barley, soybean, corn, carrot and table beet.
