Abstract
The relation of the arable land productivity in feed units (f. u.) and fertilizer use efficiency to soil fertility and economic conditions of 118 districts of Belarus for 2004-2008 period and247 cooperative farms in Gomel region for period 2001-2005 had been studied. It was found that yield response per 1 kg NPK applied varied on farm level from 3.1 to 18.0 f. u., while the profit from fertilizer use varied from 4 to188 USD per ha. Analysis of reasons preventing the realization of potential crop yields according to soil fertility indices and fertilizer used has been done.
