| Abstract: | Current situation of potassium in soils in main flue-cured tobacco planting area of Xinyang city was analyzed. The content and distribution rang of total K and available K was detailed in this article. The results showed that the average content of total K in tobacco-growing soil was 2.01% and the average content of available K was 158.22 mg/kg. The average content of total K in soil was as follow: Luoshan > Huaibin > Pingqiao = Gushi. And the average content of available K in soil was as follow: Huaibin> Luoshan> Pingqiao> Gushi.From the type of tobacco-growing soil it could be concluded that the average content of available K in downland was higher than that in paddy soil. The measure of balanced K application were also presented based on K content and distribution characteristic in field. |
