Carried out experiments have shown that hay yield increased along with the hightening of singular slurry manure dose from 50 to 200 cu. m/ha. Three-year-long period of slurry manure fertilization resulted in significant increase of content in soil of available forms of potassium, phosphorus, and less significant of total nitrogen, Slurry manure fertilization, particularly with higher doses, has caused mobilization and dislocation of iron in soil. On drained fields mobilised iron can precipitate near drain joints and possibly cause slowing down of the water runoff.
