abstract:
The paper presents the results of the studies on mineralization of nitrogen organic links in soils of two peat areas in the macro-region of the Mazurian Lakeland situated in young glacial zone of north-eastern Poland. The mineralization process results in the mineral nitrogen release, organic matter decrement as well as in the lowering of soil surface. Mineralization intensity was diversified due to habitat conditions, particularly to soil dehydration condition and moisturization. Seasonal fluctuations were noted in mineral nitrogen release. It was shown that increased mineralization, including winter, took place in dehydrated, intensively utilized peat-moorsh soils. Limited mineralization occurred in highly moisturized soils. The collected results may be used in conservation and rational use of peat soils.
