Abstract
Mineral fertilizers have been used extensively in Belarus to reduce radionuclide uptake to plants from soil and many experimental studies have been carried out to evaluate the optimum ratios of nitrates, phosphates and potassium to give the best reduction in root uptake. Mineral fertilizers are applied under conditions of radioactive contamination of a territory by changing the ratio of main elements of nutrition. Optimum N: P: K ratio is 1:1.5:2.0. The reduction of transfer of 137Cs in a grass-stand under the action of fertilizers is usually by a factor of 2.0. Radical improvement of meadows is one of the most effective countermeasures that have been implemented. Reductions of 2–4 times in root uptake are more realistic under field conditions. Radical improvement is more efficient on organic than on mineral soils. In maximal cases the cesium uptake in plants may be decreased by a factor of 10.
