The Resources、 Characters and Agricultural Applications of Bentonite in Shanxi |
| |
| Abstract: | A summary was presented of the physicochemical properties of bentonite in Shanxi.Bentonite is characterized by its better exchange, absorption, cohesiveness, etc. It was pointed out that, after used in soil, bentonite could raise the storage capacities of soil for water and fertilizer. In addition, reduce the fixations of soil for phosphorus (P) and potassium (K). The mixture of bentonite and chemical fertilizer could increase the fertilizer use efficiency(FUE).Bentonite which used as forage additive can not only improve the value of poultry raise, but also reduce the cost of fodder. Bentonite has a broad application prospect in agriculture. |
