Highest Phosphate Content Solid Fertilizer

MAP 11-52-0

Mono-Ammonium Phosphate (MAP 11-52-0) contains 11% nitrogen and 52% phosphate (P₂O₅) — the highest phosphate concentration of any commonly available solid fertilizer. It is an excellent choice where high phosphate application is required with minimal nitrogen.

MAP has a slightly acidic reaction in the soil, which can be beneficial in alkaline soils and helps improve phosphate availability. It dissolves quickly in soil moisture, making phosphate immediately accessible to plant roots.

MAP is commonly used as a starter fertilizer for a wide range of crops and is also well-suited to fertigation and liquid fertilizer blending due to its high solubility.
