Abstract
Relevance. In the situation of radioactive contamination, the main factor in reducing the transition of radionuclides from soil to green feed is the use of potash fertilizer, the effect of which on the yield of fodder crops in light soils with low local fertility is not sufficiently studied, therefore, the goal of the studies is to establish the role of potash fertilizer in increasing the yield of fodder crops.
Methods. Studies were carried out on lupine yellow, alfalfa variable, sudanese grass, millet, stockade beast, meadow timothy, annual raigras, oats, reed double-tine, meadow oatmeal, national team hedge in the south-west of the Bryansk region on floodplain sod cucumber, sod-podzolista.
Results. The highest productivity of 23.1–26.2 t/ha of green mass was found when cultivating yellow lupin. It was found that the best efficiency of fertilizer systems in the cultivation of fodder lands was revealed on floodplain sod stubble sandy soil, for each added kg received from 59.0 to 72.5 kg of crop increase.
