| Abstract: | This paper emphasized the importance of potassium element as viewed from the aspect of biochemistry. The potassium element in the soil of Chengdu plain was characterized by low content compared with the average value of nationwide soil and with the Clarke value. The reason of low content potassium in the Chengdu plain soil was analyzed.In order to improved the low content of potassium in soil, we put forward some measures which are of significance in the sustainable development and improvement of output and quality of agriculture in Chengdu plain. |
