Product Description MAP has high nitrogen and phosphorus content and is often used in agricultural production as a basic compound fertilizer. It is mainly used to prepare compound fertilizer and can also be directly applied to farmland. As fertilizer, it is most suitable to apply ammonium phosphate during crop growth. Ammonium phosphate is acidic in soil and may have adverse effects if it is too close to seeds. It is better than ordinary calcium and ammonium sulfate in acidic soil and better than other fertilizers in alkaline soil; It should not be mixed with alkaline fertilizer to avoid reducing fertilizer efficiency. If lime is to be used in acid soil in the south, monoammonium phosphate should be applied after a few days.
