Figure 4

Effects of returning cover crop to paddy field on the proportion of acid hydrolysable-N and non-acid hydrolysable-N to total-N in soil at different growing stages of rice plant. The (a) represents acid hydrolysable-N; (b) represents non-acid hydrolysable-N in soil at different growing stages of rice plant. Bars represented by different letters are significantly at P < 0.05, whereas error bars represent ±SE of triplicated data.
