Diagnostics - a basis for effective utilization of mineral fertilizers and conservation of degraded peat soil fertility

Abstract

The results of investigations on development of a method of determination of need of farm crops in nutrients and differentiation of doses of fertilizers for planned yielding capacity with due account of outcomes of diagnostics of provision of degraded peat soils with available for plants compounds of nitrogen, phosphorus and potassium are represented. Testing of a new principle of determination of doses of fertilizers in production conditions has showed the increase in yielding capacity of a grain up to 5 centner per hectare and the decrease of the costs of used fertilizers by 25 %. Profit has increased from 20 to 118 $ per hectare or by 18-50 % per conventional unit of costs.
