How to top-dress urea in mulched plots of wheat/rice?
Top dressing of nitrogenous fertilizers is not easy in fields mulched with residues of the previous crop. Residues retain for itself top dressed N and do not allow it to reach plants roots. In order to avoid temporary immobilization of N, it is appropriate to deep place the total fertilizer at about 10 cm as a single basal dose or chisel-in the fertilizer at the same depth.
