Аннотация:It was shown that local application of potassium fertilizers on soddy-podzolic soil increase grain yield of barley due to the enlargement of it proportion in general biomasse. The local (placement) method allows to balance the potassium nutrition of plants, that to remove surplus of potassium in initial periods of growth and avoid the lack of potassium at forming of grain. Application of phosphoric fertilizers, moving a requirement in application of potassium fertilizers on more late period of development, changes the optimum terms of localization of potassium fertilizers and promotes efficiency of this technology.
