Monoammonium Phosphate Fertilizer 12-61-0

Monoammonium Phosphate (MAP) 12-61-0

Maximize root development and flowering with Monoammonium Phosphate (MAP) 12-61-0. As a technical-grade, 100% water-soluble fertilizer, it is one of the most highly concentrated liquid-ready phosphorus sources available. Delivering a massive 61% available phosphate (P₂O₅) and 12% ammoniacal nitrogen, it dissolves completely and clear, leaving absolutely zero residue.

The powerful dose of phosphorus drives robust root growth, prolific flowering, and reliable fruit set. Meanwhile, the ammonium-form nitrogen gently acidifies the root zone to ensure the phosphate remains easily absorbable by the plant. This mildly acidic solution makes it exceptionally beneficial in alkaline and hard-water soils where phosphorus typically locks up.

Ideal For:

• Drip Irrigation & Fertigation: Engineered to dissolve crystal clear without clogging emitters.

• Hydroponics: A highly effective, clean nutrient source for hydroponic reservoirs.

• Targeted Feeding: Excellent for banded liquid starter applications and foliar correction.

Key Features:

• Maximum Concentration: Delivers an incredibly potent 12-61-0 NPK ratio.

• 100% Water-Soluble: Technical-grade formula leaves zero residue behind.

• Tested & Certified: CDFA registered and rigorously third-party lab-tested for heavy metals, consistently testing well below required limits.

Important Handling & Application Rules:

• Choose the Right Grade: This is the water-soluble grade designed for dissolving. If you plan to dry broadcast on fields, lawns, or garden beds, granular MAP 11-52-0 is the appropriate choice.

• Crucial Mixing Rule: In hydroponic and fertigation setups, keep MAP separated from concentrated calcium and magnesium fertilizers. Combining them in a concentrated stock will cause precipitation—always run separate stock tanks.

• Application Best Practices: Always check your solution's pH after mixing. For foliar applications, spray only in the early morning or late afternoon.
