The investigation is based on results of a field multifactorial trial, carried on leached smolnitza soil type. The crop rotation is as follows: sunflower-wheat+silage maize-corn maize-wheat+silage maize. The classic and reduced soil tillage technologies have been estimated to have very similar impact on the yield in leached smolnitza. Supplying phosphorous fertilizer application appears to be more effective. The higher nitrogen rates determine higer yields for the crop rotation as a whole, but the lower rates are much more effective.
