In the paper the results of the research conducted in 1996-2006 in the Experimental Station of IUNG - PIB in Osiny (Poland) on the object where different crop production systems are compared were discussed. The aim of this study was to evaluate the changes of selected indicators of soil fertility in the organic crop production system. Soil fertility in phosphorus and potassium, content of organic matter and soil pH were evaluated. In the organic system a decrease of potassium content and a small decrease of phosphorus in soil was observed. No significant changes in soil organic matter was observed in the organic system
