What is the difference between diammonium hydrogen phosphite and diammonium hydrogen phosphate?
1. They are all commonly used phosphate compound fertilizers in agriculture.
2. Common diammoniums include 18-46-0, 15-42-0, etc., monoammonium 11-52-0, 11-44-0, etc. The nitrogen content of monoammonium is generally less than 11%. Diammonium is more alkaline, monoammonium is more acidic. The effect of monoammonium on saline-alkali soils in northern China is better than diammonium. As long as it is used with different nitrogen and potassium fertilizers according to the fertilizer requirements of different crops, the effect is similar.
3. Due to the high total content of diammonium, high-grade phosphate rock is generally required for production, and the water-soluble phosphorus content is generally higher than that of monoammonium
