The paper presents the measurements results of microelements content in the root zone of peat-moors soil. The research was conducted on long-term Agricultural experimental plots, established in 1957, located in the Biebrza Experimental Station. The plots were used as grasslands and arable land as well as abandoned land. The amount of fertilisation of the plots was variable (0, K, PK, NPK). The obtained results shows that phosphorous and potassium content in de soil after 38 years of use under grasslands and arable land were dependent on fertilisation practice. The soil used as arable land exhibits lower contents of phophorus and potassium and higher contents of calcium in comparison to soil used as grassland. Soil pH was dependent on calcium content, the lowest values (pH=4.l) were observed in the soil used as non-fertilised grasslands while the highest (pH=4,8) in the soil fertilised with phospohorus and potassium. The abandonment of Agricultural soil use as grassland or arable land leads to systematically decrease values of potassium, magnesium and partially nitrogen contents in soil and increase values of phosphorus and calcium contents in the peat-moorsh soil.
