Calcium Lignosulphonate is used for slow-release long-lasting compound fertilizer
Calcium Lignosulphonate:
Due to the loss of nitrogen through volatilization, leaching and denitrification, phosphorus fertilizer is easy to be fixed by A13+, Fe3+, Ca2+ and Mg2+ in the soil, forming stable precipitation or forming closed storage phosphorus with iron and aluminum oxides and gradually losing its fertility. As a result, the utilization rate of fertilizer application in the season is very low.
The slow-release properties of lignin can better maintain the effectiveness of chemical fertilizer and release it slowly, which is a good controlled release material of organic compound fertilizer. When N, P, K fertilizer is mixed with lignin, the lignin slowly releases nutrient elements through physical adsorption and van der Waals force to form slow-release long-term compound fertilizer.
Slow-release long-acting compound fertilizer is suitable for rice, wheat, sorghum and other food crops, cotton, oil and other cash crops, vegetables, fruits and other horticultural crops because of the three elements of nitrogen, phosphorus and potassium, can be used as base fertilizer, topdressing and other applications. This kind of fertilizer has obvious effect of increasing yield, and maintain certain fertilizer effect in 3~4 years, and has the effect of reforming soil aggregate structure.
