    Artykuł dotyczy problemu zanieczyszczenia ekosystemu pestycydami i remediacji zanieczyszczonych gleb. Przestawiono wstępne wyniki badań akumulacji pestycydów chloroorganicznych, takich jak DDT i jego metabolitów (DDE, DDD), HCH i jego izomerów – alfa, beta i gamma w roślinności z terenów przyległych do magazynów przeterminowanych środków ochrony roślin w miejscowości Viazova i miejscowości Hlynsko w dzielnicy Zowkiwskyj w Obwodzie Lwowskim.

    They conducted an ecotoxicological survey of the soils of the sanitary zones of nonactive agrochemical warehouses and established the boundaries of chlorinated organic pesticide-polluted zones. Studies on dark grey, podzolized soils in the conditions of the Western Forest-Steppe of Ukraine found that there is a spatial migration of organochlorine pesticides and the degree of chemical degradation of soils is estimated.

    The content of isoflavonoids in the green mass of the leading Ukrainian soybean varieties by the vegetation stages were determined, as well as the presence of a series of phenolic compounds in different vegetative organs of soybean of Podilska-1 variety, which is recommended for combined sowing for silage. The scientific evidence of the influence of these compounds on the butter-fat yielding capacity and reproductive properties of cows, which corresponds with the results of years-long usage of corn-soybean silage as a component of forage mixture for high-producing cows under single-type feeding throughout the year within conditions of a dairy unit with 1050 cows.

    The work leading to creation of a new breed - Carpathian Ukrainian mountain sheep with high quality mixed carpet wool cover came to an end in 1993. It was achieved by breeding local ewes with thick wool covers with Tsigai breed rams. In terms of milk yield and wool quality the new breed was significantly more valuable than sheep of local breeds. At the same time they adapted well to the specific mountain climate and management system. In the current situation of rapid decrease in demand for wool, the breed is still competitive due to universal production objectives and possibility of using not only its good quality wool but also milk and sheep meat. The current direction of improvement is raising milk yield in the sheep of this breed.
