Data of long-term stationary field experiments were generalized over the period between 1972 and 1999, and changes in patterns of the humus status and nutritive regime of gray forest soils as well as of the productive moisture utilization by plants upon the long-term application of mineral fertilizers in different crop rotations were revealed for the opol'e regions of Central Russia. Some causes of the latent negative effect of fertilizers on an agrocenosis (disturbance of biological processes in the soil because of the physiological acidity of mineral nitrogen and excessive accumulation of nitrates in the root-inhabited layer depleted in phosphorus) were analyzed.
