METHOD FOR REDUCING NITRATE CONTAMINATION OF GROUND WATER IN DRAINED MEADOW |
摘要 |
agriculture. SUBSTANCE: method involves creating hay and grazing meadows and sowing to perennial grasses in spring under covering of short-duration crop (vetch + oat, annual rye grass, summer turnip, oil radish). Method allows content of nitrate nitrogen in ground water to be reduced by 1.3-24 times and, as a result, forage production to be safe for environment. EFFECT: improved ecology control by reducing concentration of nitrates in ground water to safe level. 1 tbl
