Influence of fertilization on the crop rotation productivity and the balance of essential nutrients in the soil

The article shows the influence of different rates and combinations mineral fertilizers on balance essential nutrients in four-field crop rotation (winter wheat, corn, spring barley, soybean) during eight years context incorporation into soil or removal a non-commercial part yield field. stationary field experiment was performed black podzolized heavy loamy Right-Bank Forest-Steppe. scheme included 11 variants separate applications as well control without fertilization. It has been established that annual together with grain harvest nitrogen makes up biggest share (64.4–149.9 kg hа-1), then phosphorus – 21.1–51.4 hа-1 depending fertilizing rotation. variant N110P60K40 provides optimal intensity nitrogen, phosphorus, potassium (103, 122, 111%, respectively) when non- marketable is left for When this removed from there deficit (76, 76, 61%, even average application N110P60K80. use non-marketable agricultural products fertilization N110P30–60K40–80 allows compensation losses 24%, 33%, 71%
