Boca Hydro MAP 12-61-0

Fully Water-Soluble Phosphorus & Ammoniacal Nitrogen for Roots, Bloom, Hydroponics & Fertigation

Boca Hydro MAP is a premium-grade, fully water-soluble Monoammonium Phosphate 12-61-0 fertilizer designed to provide a clean, concentrated source of phosphorus and ammoniacal nitrogen.

MAP supports strong root development, transplant establishment, flowering, fruiting, and overall plant energy transfer. Its ammonium nitrogen helps gently acidify the root zone, improving phosphorus availability and helping plants access nutrients more efficiently.

This clean, chloride-free and sodium-free formula dissolves quickly and completely in water, making it excellent for hydroponics, fertigation injectors, foliar sprays, soil drenches, concentrated stock solutions, and custom fertilizer blends.

12-61-0 High Phosphorus Ammoniacal Nitrogen Chloride-Free Sodium-Free Fully Water Soluble Root & Bloom Support

Fully water soluble, chloride-free, sodium-free, and made for precision plant nutrition.

Product Benefits
High Phosphorus Formula Provides 61% available phosphate to support root growth, transplant establishment, flowering, fruiting, and plant energy movement.
Root Development Support Phosphorus supports early root growth, root-zone recovery, transplant recovery, and strong plant establishment.
Ammoniacal Nitrogen Supplies 12% ammoniacal nitrogen, which helps gently acidify the root zone and improve phosphorus availability.
Clean Water Solubility Dissolves quickly and cleanly for hydroponics, fertigation, foliar feeding, soil drenches, and stock tank preparation.
Custom Nutrient Programs Contains no potassium, calcium, or magnesium, making it easy to pair with other fertilizers when building custom feeding programs.
Why Use MAP?
Transplants & Rooting Excellent for early establishment, transplant recovery, root development, and crops that need extra phosphorus at the beginning of growth.
Flowering & Fruiting Crops Useful for tomatoes, peppers, citrus, avocado, mango, berries, vegetables, flowers, and other crops with high phosphorus demand.
Hydroponics Provides clean, highly soluble phosphorus and ammoniacal nitrogen for precision hydroponic nutrient programs.
Fertigation Ideal for injector systems when used in a separate stock tank and diluted into the final irrigation water.
Compatibility Note: Boca Hydro MAP should not be mixed in the same concentrated stock tank with calcium nitrate, calcium products, magnesium nitrate, magnesium sulfate, or other concentrated materials that may react with phosphates. Use separate stock tanks and allow products to mix only after dilution in the final irrigation water.
Grower Tip: MAP is especially useful during rooting, transplant recovery, early growth, bloom support, fruiting, and periods when plants need a clean phosphorus source without adding potassium, calcium, magnesium, sodium, or chloride.

Important Mixing Notes

MAP is a concentrated phosphorus and ammoniacal nitrogen source. It is commonly used to support rooting, transplant recovery, flowering, fruiting, and strong plant energy movement. MAP does not provide potassium, calcium, magnesium, sulfur, or micronutrients, so it should be used as part of a complete fertility program.
Do not mix MAP in the same concentrated stock tank with calcium nitrate, chelated calcium, magnesium nitrate, magnesium sulfate, or other concentrated calcium or magnesium products. Use separate stock tanks and allow products to mix only after dilution in the final irrigation water.
Always start with lower rates on sensitive crops or new varieties. Foliar applications should be tested on a small area before full application. Avoid spraying during extreme heat, drought stress, or intense sunlight.
