The appearance of transparent or translucent granular, the Lumpy Silica Gel in the role of fertilizer and the performance of spherical silica gel is the same, but according to the needs of silicon fertilizer processing will be spherical shaped products. The total silicon content in the soil is about 31%, of which about 99% belongs to the crystalline and amorphous form. It mainly exists in quartz and secondary clay ore, which cannot be used as the nutrient by plants. Only a small amount of monosilicic acid [orthosilicic acid, Si(OH)4] in the soil solution can be absorbed and utilized by plants, and this part is called effective silicon. The addition of silica gel to the fertilizer effectively increases the silicon content.

Silicon is an important nutrient element in plant composition, and is listed as the fourth major element after nitrogen, phosphorus and potassium in the international soil boundary.
