| Abstract: | The effect of the added As on growing of the vegetable and the critical value of the vegetable were investigated in this paper, and the alalytical method of the correlation degree of the grey system was used to relate them with the soil porperties. It was showed that the critical values of arsenate normally are as follow: red purple soil > grey brown purple soil > red brown pruple soil. |
