EFFECT OF NITROGEN FERTILIZER AND MAIZE STRAW INCORPORATION ON NH4+15N AND N0(3) -15N ACCUMULATION IN BLACK SOIL OF NORTHEAST CHINA AMONG THREE CONSECUTIVE CROPPING CYCLES

A pot experiment was conducted to evaluate the effect of nitrogen (N) fertilizer and maize straw incorporation on the accumulation of NH4+-15N and N0(3)--15N in soil inorganic N pool among three consecutive cropping cycles, aimed to search for an effective N management practice to decrease superfluo...

The results showed that the amounts of soil NH4+-15N, N0(3)-15N and inorganic 15N, and their percent to applied 15N-labeled fertilizer declined significantly with sampling time (p ≤ 0.001).Compared to low N application rate (44.64 mg N kg-1 soil), high N application rate (89.28 mg N kg-1 soil) enhanced significantly the amounts of soil NH4+-15N, N0(3)--15N and inorganic 15N by 238.6%, 132.9% and 197.3%, respectively (p ≤ 0.001).
