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

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...
