The changes of soil nitrogen and carbon contents in a long-term field experiment under different systems of N fertilization

Original language description

Content of N and C in soil were investigated in a long-term field experiment under different systems of N fertilization. Chernozem and Cambisol were extracted using hot water (Nhwl, Chwl) and 0.01 M CaCl2 (NCaCl2, CDOC). The Ct/Nt ratio in Chernozem was9.6 : 1 and in Cambisol 6.1 : 1. The lowest Ct/Nt ratio in both experiments was found in the control treatment. Results showed that C and N compounds are less stable in Cambisol, which leads to a higher rate of mineralization. In the Chernozem, Nhwl formed 3.66 % from the total N content in the soil whereas NCaCl2 formed only 0.82 %. Chwl formed 2.98 % and CDOC 0.34 % from total C content. Cambisol contains 4.81 % of Nhwl and 0.84 % of NCaCl2 from the total N amount and 5.76 % of Chwl and 0.70 % of CDOCfrom the total C content, respectively. Nitrogen extracted by 0.01 M CaCl2 formed only 22.4 % of N extractable by hot water in Chernozem and 17.5 % in Cambisol. The lowest C/N ratios were obtained after the CaCl2 extraction (3.0 ? 6.2 :
