In the conditions of the Republic of Belarus on sod-podzolic sandy soil in course of the research there was studied the influence of organic fertilizer application on yield of maize (Zea mays) green mass, removal and balance of main nutrients with crop yield. The stationary experiment was realized in 2010-2011 in 'Suvorov Experimental Station' (Uzda district, Belarus). As a result of realized research it was revealed that in the conditions of cultivation of maize for green mass the application of equivalent doses of organic fertilizer (obtained at the output of a biogas unit) was similar to the effect of organic fertilizers used for biogas production (poultry manure and cattle fluid manure), as well as mineral fertilizers applied in dose-aligned nitrogen on the sod-podzolic sandy soil. Yield of corn green mass was at the level of 550-562 kg/ha in these options at an average of two years. Specific removal of nutrients from one ton of corn green mass (75% moisture) averaged: N - 3.2 kg, P2O5 - 1.5 kg, K2O - 4.8 kg, CaO - 0.4 kg, MgO - 0.4 kg.
