Product Description
Mono-Ammonium Phosphate 12-61-0
Application:
Kagro 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, also it can serve as a high quality source of phosphorus also during other stages of the growth cycle.
Because of unique product characteristics, MAP can be applied through any irrigation system and on any growing medium. MAP is moderately acidic. Therefore, it is not corrosive to fertilizer pumps or to irrigation equipment.
(1). Compatibility
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.
(2). Quantitative Nutrigation
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 AN and K .
(3). Proportional Nutrigation
The phosphorus concentration in the irrigation water depends on the quantity of MAP in the tank mix, and on the injection ratio. Use the following table to calculate the quantity of MAP and the injection ratio needed to reach a given concentration in the irrigation water.
(4). Foliar Feeding
Foliar spray with MAP is effective in supplying phosphorus whenever quick response to deficient plants is required. It should be considered a supplemental method to soil applied phosphorous. The concentration of MAP solutions can be increased according to leaf age.
On young leaves, spray concentration of 0.5% MAP is recommended in most crops. On mature leaves and more tolerant crops higher concentration (1.0% or more) may be applied.
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 compatibility of your intended spray-mix by preparing a sample of the spray materials at their recommended concentrations in order to rule out the possibility of a detrimental cross reaction. This mixture should be sprayed onto small area prior to commercial treatment, in order to assess whether an adverse effect occurs.
