The paper shows results of a field experiment concerning changes of easy hydrolysing nitrogen in sandy soil, caused by the application of calcium oxide and carbonate, and mineral fertilizer, in crop rotation. The 4-year experiment was carried out on a brown, lixiviated soil, considered to be a very light soil. Liming caused a decreased of hydrolysing nitrogen in soil, independently of the kind and dose of lime. The limed soil contained various amounts of easy hydrolysing nitrogen which depended on the crop rotation. No influence of mineral fertilization (NPK) could be found in regard of the easy hydrolysing nitrogen in sandy soil. This indicates that the source of easy hydrolysing nitrogen are mainly nitrogen compounds present in sandy soil
