Fertilizer-grade phosphate: How to make every acre of farmland harvest 300 kilograms more?

A farmer's proverb says: "Sufficient phosphorus fertilizer will make the seedlings thick." Our fertilizer-grade phosphate contains 98% soluble phosphorus. When applied to the fields, the roots are like a dragon entering the sea and digging three inches deep, and the absorption capacity increases by 50%. A rice farmer wrote: "In previous years, the yield per mu was 1,000 kilograms. After using this fertilizer, the yield per mu increased by 300, and the grains were full like pearls." The magic of this fertilizer is that it is suitable for different soils: black soil is matched with high-phosphorus type, red soil is matched with slow-release type, and it is also accompanied by field guidance from agricultural technicians. Today, corn, fruit and vegetable, and tea gardens all use it. It not only increases yields, but also strengthens the resistance of crops to stress, and can also ensure harvests in years of drought and flood. This is a practical strategy to help farmers increase their income.
