Fumed silica has many applications in the agricultural field, especially in fertilizers and plant growth.
First, fumed silica can be used as a suspending agent and anti-settling agent to stabilize the liquid system in liquid water-soluble fertilizers, prevent fertilizer stratification and sedimentation, and thus improve the utilization rate of fertilizers. At the same time, it can also improve the soil's easy compaction, loosen the soil, and improve soil quality.
Secondly, fumed silica has a strong physical adsorption function, which can bring a slow-release effect and make the soil have a certain fertilizer retention capacity. In addition, it increases the silicon content in the soil, which is beneficial to plant growth. Studies have shown that nano-silicon dioxide can promote the growth of seedlings and seed germination of various plants to a certain extent, improve the photosynthesis efficiency and dry matter mass of plants, and promote the absorption of nutrients such as nitrogen, phosphorus, and potassium.
In general, fumed silica, as a new type of functional material, has broad application prospects in the agricultural field. It can improve the utilization rate of fertilizers, improve soil quality, promote plant growth, and bring significant benefits to agricultural production. With the continuous development of nanotechnology and the continuous expansion of its application fields, the application of fumed silica in the agricultural field will become more extensive and in-depth.
