sod-podzolic soils

Various fertilizer system impact on the nitrogen mode features of the sandy sod-podzolic soil

Nitrogen in the sod-podzolic soils is in the minimum and its deficiency, coupled with insufficient and unstable heat regime in the region, reduces the productivity of Northern agrocenoses. On the other hand, excess of nitrogen fertilizers causes an increased mineralization of natural nitric compounds, soil deterioration and weakens natural soil restoration processes.

Fertilizer mixtures with wastewater sludge on sod-podzolic soils

The article presents the characteristics of mixtures based on wastewater sludge (WWS) and organic elements (sawdust, peat, straw). There is the fertilizers influence on nutritive regime of sod-podzolic soil, experimental crop yield (vetch-oat mixture and winter rye) and their quality.
