The experiment was carried out to study the effects of long-term fertilization on the distribution of soil organic carbon and nitrogen in density fractions on black soil in Hailun national field research station.Results showed that: the effect of N fertilizer on the organic carbon and nitrogen of the primary soil was positive
but which was less obvious than that of NPKOM.The trend of the amount of soil organic carbon
which existed in the fraction of soil
was that HF(heavy fraction) >LF(free light fraction)>...
