The leading index of ground fertility – the humus, is found in close-fitting depending on the applied fertilization systems in the crop rotation. Crop fields where the fertilizers haven’t been used for a long period of time (more than 50 years) show a reduction of the humus content of about 0,30- 0,50% from its initial content in the layer of ground of 0-60 ńm. The use of mineral fertilizers also reduces the small humus content in the ground. While the use of organic and organic-mineral fertilizers enlarges the humus content with about 0,25-0,30% compared with its initial content.
