Effect of N fertilizers on (A) NH4+-N in fine texture (B) NH4+-N in coarse texture (C) NO3ˉ-N in fine texture (D) NO3ˉ-N in coarse texture soil under maize. Error bars represent the standard error of the mean of three replicates. (CK = control, U100 = 100% recommended N by urea, C100 = 100% recommended N by CSRF, B100 = 100% recommended N by BSRF, B75 = 75% recommended N by BSRF, B50 = 50% recommended N by BSRF).
