Description: Utilizing Ammonium Polyphosphate as an efficient compound fertilizer, this solution provides soil phosphorus enhancement for agricultural planting, boosting crop yields and soil health.
Product Details: Our APP soil improvement solution centers on Ammonium Polyphosphate (APP) as a liquid nitrogen-phosphorus fertilizer, which slowly hydrolyzes into orthophosphate, gradually increasing available phosphorus in the soil and enhancing phosphorus use efficiency for better crop growth. Suitable for various soil types, especially calcareous ones, it improves phosphorus mobility, effectiveness, and availability, promoting root development and nutrient uptake, such as significantly increasing maize yield and phosphorus efficiency. We offer modified products like APP-Mg and APP-Fe to supply magnesium or iron micronutrients, supporting slow-release fertilization with extended phosphorus nutrition, requiring no additional moisture for dissolution. The product is non-toxic and biodegradable, compliant with international environmental standards, suitable for foliar or direct soil application to address phosphorus deficiencies. As a Hubei-based manufacturer, we provide customized formulations and technical guidance, ensuring effective fertilization strategies to support sustainable agriculture and enhanced crop productivity.
Key Benefits:

• Improved P Utilization: Dissolves phosphates with Ca , Mg, enhancing availability for maize growth. PolyP advantageous for plant P nutrition, yield.

• Slow-Release: Liquid P fertilizer, quick to ortho in 2 days, sustained.

• Eco-Friendly: Non-toxic, low ecosystem impact.

Application Examples:

• Calcareous soils: Improves P mobility for roots, maize yield. Higher polymerization better for solubility, yield.

• Liquid NP 11-37: Broad application time, no moisture needed, prolonged P. Wheat: Highest P release at 150 min.
