Aqualis® MAP Solub – Phosphate Fertilizer


Aqualis® MAP Solub is a fully water-soluble monoammonium phosphate fertilizer in the form of a free flowing, crystalline powder. It is a popular P fertilizer in fertigation programs. Suitable for all fertigated crops under drip irrigation, sprinkler systems, for fertigated greenhouses. It is ideal for vegetables, fruits and flowers in any growing medium, as well as open fields and orchards.

It is important to use this product in the first stages of growth of plants, when the availability of P is critical for the establishment of root system. Ideal when you are looking for the combination of P and N.
The acidic pH of the Aqualis® MAP Solub increases the availability of the phosphate and the micronutrients.

Aqualis® MAP Solub – Application

Aqualis® MAP solub is recommended in the first stages of growth of plants, its high P solubility and availability enhances root development and establishment of seedlings.

Aqualis® MAP solub is usually mixed with soluble sources of N (urea, AN) and K (KNO3, KCl), to balance the N:P:K ratio suitable to the crop requirement.

Due to especially pure H3PO4 Aqualis® MAP solub, it can be used as a foliar spray or added to irrigation water without any residues.

Aqualis® MAP solub is compatible with the majority of pesticides and fertilizers. When Aqualis® MAP solub is to be mixed with other components, it is recommended to perform a combatibility test prior to tank mix.

Aqualis® MAP solub can be mixed with all water-soluble fertilizers, except for calcium fertilizers and concentrated magnesium solutions. In hydroponic systems, it should normally be added to the B tank.

Aqualis® MAP solub has a buffering effect which will help stabilize the pH of the solution at around 4.5. Its acid reaction offsets the calcareous soils, thus increasing the availability of P and micronutrients.
