POTASSIUM UPTAKE WITH PRECIPITATION, CONCENTRATION IN SOIL SOLUTIONS AND MIGRATION FROM ARABLE SOD-PODZOLIC SOILS OF BELARUS (ОN THE DATA OF LYSIMETRIC RESEARCHES IN 1981–2012)

Abstract

The article deals with the results of long term experiments determining migration and balance of nutrition elements in the system: precipitation-soil-fertilizer-plant. Studied is potassium uptake with precipitation on soil surface, its losses when it is leached from sod-podzolic soils of different granulometric composition (from soil layer 1,0–1,5 m) during long agricultural use (1981–2012): different seasons of the year and decades (1981–1990, 1991–2000 and 2001–2010), and years with different degree of soil moisturization.
