Changes in Soil C/N Ratio Influenced by Nitrogen Fertilization

Fertilization with different amounts of mineral nitrogen (0 do 300 kg N /ha) have been applied continuously, from 1996 till 2006, in a stationary field experiment established on drained Pseudogley in Central Croatia. Trial treatments included annual fertilization with different mineral nitrogen rates, respectively with 0, 100, 150, 200, 250 and 300 kg N/ha. Analyses of total nitrogen, N-NO3, N-NO2, N-NH4, total carbon content and C/N ratios in soil are presented for three investigated depths (0-30 cm, 30-55 cm and 55-80 cm), for soil samples taken three times during 2006 (April, July and December). Total nitrogen and carbon content were determined by dry combustion method and content of N-NO3, N-NO2, N-NH4 by ion chromatography method. First soil samples were taken at 12th of April 2006, before second top dressing of winter wheat ; second sampling was just after the harvest (17. July) and third sampling was at 18th of December. Differences in total nitrogen, N-NO3, N-NO2, N-NH4, carbon content and C/N ratios have been noted after eleven years of fertilization, according to different nitrogen rates and soil depths.
