| Abstract: |
| Studies on the correlation between the content of residual mineral nitrogen in soil rooting brofile(0-100cm)and the yield of wheat were conducted during 1984- 1986 in some regions of North China.The results showed that high correlation was found between these two correlative factors.Therefore Nmin content can be used as an index for recommendation of nitrogen fertilizer. |
| Key words: soil rooting profile residual mineral Nmin |
