In the conditions of the Republic of Belarus there were analyzed the influence preceding crops and ways of their products use on yielding capacity of grain-grass- hoed crop rotation grown on anthropogennically transformed soils of Belarusian Polesye area. Maize (Zea mays) grown for green mass was selected as a standard for the comparative efficiency of other preceding crops: there were used different fertilizing variants - N120P80K120 and 60 t/ha of manure + N70P80K120. Phosphorous and potash fertilizers in doses of P80K120 were applied for presowing cultivation for winter rye (Secale cereale) and in spring nitrogen fertilizers in dose N70 were applied as top-dressing. Winter rye was harvested in booting stage before ear formation. Soil was burst by plate feed and postcut crops were sowed. For the following crop rotation crops there were used the following fertilizers: N70P60K120 for potato (Solanum tuberosum); N50P60K120 were applied for barley (Hordeum vulgare); N60P60K120 were applied for grain-leguminous grasses. Research results showed that application of preceding crops combinations of winter rye - Australian field pea (Pisum arvense L.) – oil radish (Raphanus sativus var. oleifera) or winter rye – oil radish for green fodder made it possible to obtain the productivity of crop rotation cultures at the level of 69,1-75,4 c/ha of feed units of high quality.
