COBALT-CONTAINING PEAT-ZEOLITIC FERTILISER OF PROLONGED ACTION

摘要

FIELD: agriculture. ^ SUBSTANCE: cobalt-containing peat-zeolitic fertiliser of prolonged action which comprises lowland peat and natural zeolite modified by trace element cobalt in the ratio 2.1:1-2.6:2. Natural zeolite which is crushed to the grain size of 0.5-0.7 mm, is saturated with the 0.009-0.011% solution of cobalt sulfate CoSO4 for 5-7 hours at a weight ratio of natural zeolite and solution of cobalt sulfate 1:8-1:9. ^ EFFECT: invention enables to improve the biological productivity of low-productive cryoarid and cryomorphic soils, crop yield, and to improve their quality composition. ^ 3 ex
