The percentic recovery and balance of fertilizer nitrogen can be determined by different methods. In this study, quantitative difference method in recovery of Nitrogen of above-ground dry matter was applied to investigate the uptake of field applied nitrogen by maize cultivated in an orthic oxisol soil. It was found that the maximum uptake of fertilizer N is about 75 % decreasing at the end of the growing period to about 65%. About 25% of the N remains in the upper part of the profile, while about 10% can not be localized and presumably lost by denitrification.
