M.A.P Mono Ammonium Phosphate 12-61-0 25kg

As a highly efficient source of phosphorus and nitrogen for plants, Haifa MAP™ is recommended for use at the beginning of the growing season, when phosphorus availability is crucial for the establishment of the root system. Haifa MAP™ can be tank-mixed with other fertilizers to meet crop nutritional needs throughout the growth cycle

Haifa MAP™ is suitable for preparation of fertilizer blends and production of liquid fertilizers.

Note: Haifa MAP™ should not be mixed with calcium or magnesium fertilizers.

The advantages of Haifa MAP

• Fully water-soluble
• Consists of 100% plant nutrients
• Highly-concentrated source of phosphorus for plants (61% P2O5 / 27% P)
• Free of chloride, sodium and other detrimental elements for plants
• Moderately low pH (safer and less corrosive compared to urea phosphate)
• Suitable for Nutrigation™ ( Fertigation), foliar application and production of fertilizer blends and nutrient solutions
• Not only is Haifa MAP™ an efficient source of phosphorus, but it also facilitates plant uptake of the phosphorus naturally present in the soil. This is due to the ammonium (NH4+) in Haifa MAP™, which lowers the pH in the root zone and thus enhances phosphorus availability.

Application Recommendations

nutrition

• Due to its unique characteristics, Haifa MAP™ can be applied through any irrigation system and on any growing medium. Unlike phosphoric acid, Haifa MAP™ is moderately acidic. Thus, it does not form corrosion on fertilizer pumps or irrigation equipment.

Compatibility

• Haifa MAP™ is compatible with most water-soluble fertilizers, except for fertilizers containing calcium (Ca++) or magnesium (Mg++).
• To apply Haifa MAP™ in combination with calcium or magnesium fertilizers, use two fertilizer tanks. If the system includes only one tank, apply these fertilizers at different times.

Quantitative Nutrigation

• Each kilogram of Haifa MAP™ in the tank provides 610 grams of phosphorus oxide (P2O5) and 120 grams of ammonium-nitrogen (N-NH4).
• Example: from initial establishment to flowering, open-field grown tomatoes require phosphorus at a rate of 1.5 kg P2O5 per hectare per day. To provide this, apply Haifa MAP™ at a rate of 2.5 kg per hectare per day. This will supply also 0.3 kg nitrogen per hectare per day. To complete nitrogen and potassium requirements, apply ammonium nitrate and Multi-K™ (potassium nitrate).

Proportional Nutrigation

• The phosphorus concentration in the irrigation water depends on the quantity of Haifa MAP™ in the tank mix, and the injection ratio. Use the following table to calculate the quantity of Haifa MAP™ and the injection ratio needed to reach a given concentration in the irrigation water.

Foliar Nutrition

• Foliar spray with Haifa MAP™ is effective in supplying phosphorus whenever a quick response to deficient plants is required. It should be considered as a supplemental method to soil-applied phosphorous. The concentration of Haifa MAP™ solutions can be increased according to leaf age.-
• On young leaves, a spray concentration of 0.5% Haifa MAP™ is recommended in most crops. On mature leaves and more tolerant crops, a higher concentration (1.0% or more) may be applied.
• Haifa MAP™ is compatible with most commonly used pesticides and fertilizers. However, it should not be mixed with calcium or magnesium fertilizers. It is advisable to confirm the compatibility of your intended spray-mix by preparing a sample of the spray materials at their recommended concentrations to rule out the possibility of a detrimental cross-reaction. This mixture should be sprayed onto a small area before commercial treatment, to assess whether an adverse effect occurs.
