Mono Ammonium Phosphate
This MAP is a fully water-soluble mono-ammonium phosphate (12-61-0) fertilizer, a highly efficient source of phosphorus and nitrogen for plants. MAP is recommended for use at the beginning of the growing season, because phosphorus availability is crucial for the establishment of root system at this stage. MAP can serve as a high-quality source of phosphorus also during other stages of the growth cycle. Its high purity and water-solubility make MAP an ideal fertilizer for fertigation and for foliar application. MAP is suitable for preparation of fertilizer blends and production of liquid fertilizers

THE ADVANTAGES OF 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 the fertigation, foliar application and production of fertilizer blends and nutrient solutions
Double benefit: Not only that MAP is an efficient source of phosphorus, it also facilitates plant uptake of the phosphorus naturally present in the soil. This is due to the ammonium (NH4 +) in MAP, which lowers the pH in the root zone and thus enhances phosphorus availability.
Because of unique product characteristics, MAP can be applied through any irrigation system and on any growing medium. Unlike phosphoric acid, MAP is moderately acidic (see table on the 1st page). Therefore, it is not corrosive to fertilizer pumps or to irrigation equipment.
MAP is compatible with most water-soluble fertilizers, except for fertilizers containing calcium (Ca++) or magnesium (Mg++). To apply MAP in combination with calcium or magnesium fertilizers, use two fertilizer tanks. If only a single fertilizer tank is available, apply those fertilizers at different times.
Each kilogram of MAP in the tank provides 610 grams of phosphorus (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 MAP at a rate of 2.5 kg per hectare per day. This will provide also 0.3 kg nitrogen per hectare per day. To complete nitrogen and potassium requirements, apply ammonium nitrate and K (potassium nitrate).
