As a result of three-year experiments, carried out on the radio-active contaminated sod-podzol sandy soil, the influence of different seeding rates of lupine grass mixtures on two backgrounds of potash fertilizer in doses K180 and K120 on the yields of green mass, grain forage and specific activity of Ce137 in the yields of marketable products has been determined. The optimal seeding rates of different lupine-grass mixtures ensuring maximum yields of green mass at the level of 32,1-35,4 t/ha, grain forage - 2,56-2,91t/ha and specific activity of Ce137 being lower in levels set by sanitary standard (SanPin 2.3.2 1078-01) on the background of potash fertilizer in dose K210.
