This is a natural source of silica and it is having 78% Silicon content 98% water solubility increases crop production. Increases uptake of phosphorus, thereby decreasing phosphorus leaching by 40-90 Reduces loss of nutrients and water through leaching and microbial activity. Increases potash- fertilizer efficiency Protects natural waters against heavy metals, nutrients and organic toxins. Promotes more predictable and vigorous plant growth Results in higher survival rates with greater yields. Makes plants less palatable to insects
