Effect of the Rates and Schedules of Nitrogen Fertilizer Application on the Accumulation of <sup>137</sup>Cs in Plants and the Yielding Capacity of Cereal Crops
Studies performed on a loamy sandy soddy-podzolic soil contaminated with 137Cs at a rate of 500-660 kBq/ m2 showed that the application of nitrogen fertilizers enhanced the migration of 137Cs in the soil-plant system. A more significant input of 137Cs into plants was observed at the split application of nitrogen fertilizers. The negative effect of increasing nitrogen rates decreased at the application of increased (K120) and high (K150) rates of potassium fertilizers.
