Polinkevych V. Agroecological bases of creating pasture conveyor for young beef cattle under the conditions of radioactive contamination of Ukrainian Polissya

The test object is the process of creating pasture phyitocenosises by choosing ecologically safety ways of soil tillage, types and doses of fertilizers. The aim is to choose economically advantagedes and ecologically safety ways of soil tillage, types and doses of fertilizers as well as the highest yielding crops while creating summer feeding base for beef cattle in the zone of radioactive contamination. The methods used are field, laboratory, radiochemical, agroecological, calculation and statistical ones. Theoretical results - the efficience of the influence of different agroecologocal factors on annual and perennial agrophytocenosises yielding capacity and radionuclides contamination. Practical results - the model of pastures conveyor on lends contaminated with radionuclides for young beef cattle was made. The novelty - the effective types and doses of fertilizers for adoption the technological model of pasture conveyor on the basis of different time ripening perennial grass mixture combinationand annual fodder crops.
