Haifa MAP 12-61-0 Mono Ammonium Phosphate 25kg: Water Soluble High Phosphorus Fertiliser

Haifa MAP: A Technical Grade Monoammonium Phosphate Fertiliser

Haifa MAP is a concentrated, fully water soluble monoammonium phosphate fertiliser with an analysis of 12-61-0. It supplies 61% phosphate (P₂O₅, equal to 27% phosphorus) and 12% nitrogen, all in the ammonium form. As a technical grade product, it dissolves completely with no chloride, sodium or residue, making it ideal for fertigation, drip irrigation, hydroponics, foliar feeding and preparing custom fertiliser blends and liquid feeds. It's made by Haifa Chemicals and available in 1kg, 2kg, 4kg and 25kg packs.

What Is Mono Ammonium Phosphate Fertiliser?

Mono ammonium phosphate (MAP) is one of the most concentrated sources of phosphorus for plants. It comes in two main forms:

• Technical grade, water soluble (12-61-0): high purity powder or crystals that dissolve fully, for fertigation, hydroponics and foliar sprays. Haifa MAP is this type.
• Granular (around 11-52-0): for spreading or banding into soil at planting.

Is MAP Fertiliser Good for Root Growth?

Yes. Phosphorus drives early root development, energy transfer and establishment, so a high phosphorus fertiliser like MAP is most valuable at the start of the season, at planting and transplanting, and during early growth. Haifa recommends MAP at the beginning of the growth season, when phosphorus availability is crucial for building the root system.

Moderately Acidic for Better Phosphorus Uptake

The ammonium in Haifa MAP lowers the pH in the root zone, which helps keep phosphorus available to plants, especially in neutral to alkaline soils and water. Haifa MAP solutions are moderately acidic, around pH 4.2 to 4.7 depending on concentration, which is safer and less corrosive than urea phosphate.

What Plants Need High Phosphorus Fertiliser?

• Seedlings and transplants establishing new roots
• Vegetables and crops at planting, including tomatoes, capsicums and cucurbits
• Fruit trees and vines at the start of the season
• Turf, sports fields and ornamentals during establishment
• Crops in phosphorus-deficient soils confirmed by a soil or leaf test

Avoid high phosphorus fertilisers on phosphorus-sensitive Australian natives, such as grevilleas, banksias and other Proteaceae.

How to Use Haifa MAP

• Fertigation and drip: dissolve fully in water and inject through the irrigation system. Solubility increases with water temperature, at about 37g per 100g of water at 20°C.
• Foliar spray: on young leaves, a 0.5% solution (about 5g per litre of water) is recommended for most crops. Concentration can be increased as leaves mature.
• Blends and liquid feeds: combine with other soluble fertilisers to build a complete NPK program.
• Follow the rate for your crop, growth stage and system, guided by a soil or leaf test.

Don't Mix with Calcium or Magnesium

Haifa MAP must not be mixed in the same tank with calcium or magnesium fertilisers, such as calcium nitrate or magnesium nitrate, as they form insoluble precipitates that block drippers and filters. Use two separate stock tanks. Haifa MAP is compatible with most commonly used pesticides and other fertilisers, but always jar test before tank mixing.

Storage and Handling

Soluble fertilisers absorb moisture from the air, so keep the bag tightly sealed in a cool, dry place to prevent caking. Avoid runoff into drains and waterways, as excess phosphorus can cause algal blooms. Wear gloves and eye protection when handling the powder.

Frequently Asked Questions

What is Haifa MAP 12-61-0?

It's a technical grade, fully water soluble mono ammonium phosphate fertiliser with 12% ammoniacal nitrogen and 61% phosphate (27% phosphorus), made by Haifa Chemicals for fertigation and foliar feeding.

Can Haifa MAP be mixed with calcium nitrate?

No. Mixing MAP with calcium or magnesium fertilisers in the same tank causes precipitates that block irrigation lines. Use separate stock tanks.

What is mono ammonium phosphate used for?

It supplies concentrated phosphorus and nitrogen, mainly for root establishment early in the season. It's used in fertigation, hydroponics, foliar sprays, fertiliser blends and starter programs.

Is MAP fertilizer water soluble?

Technical grade MAP like Haifa MAP is fully water soluble and dissolves with no residue. Granular agricultural MAP is designed for soil application and isn't suitable for drip systems.

Is MAP fertilizer good for root growth?

Yes. Its high phosphorus content supports strong root establishment, which is why it's applied at planting and in early growth.

What plants need high phosphorus fertilizer?

Seedlings, transplants, vegetables at planting, fruit trees at season start, turf during establishment and crops in phosphorus-deficient soils. Avoid it on phosphorus-sensitive natives.

How much Haifa MAP do I use as a foliar spray?

A 0.5% solution, about 5g per litre of water, is recommended on young leaves for most crops. Rates can increase as leaves mature.
