Advantages
  • Highly efficient source of phosphorus as phosphate (H2PO4-) which promotes rapid absorption by the plant
  • Select MAP provides an acidifying effect on the soil solution favoring solubility of phosphorus and micronutrients.
  • Freely soluble and quickly dissolving.
  • Product of high purity, no residue or contaminants
Description

Select MAP is a whitish crystalline powder, free of chloride and sodium. It is the ideal fertilizer for increasing the availability of soil-phosphorus, especially in calcareous soils. Select MAP consists in high purity of nutrients and no residue or contaminants.

Directions for use

Select MAP can be used in fertigation of most of the crops, in all growing stages. It can be used especially in the early stages of plant growth to promote optimal development of the root system as well at the stages of flowering and fruit formation. Do not mix the product with Calcium containing products (e.g. Nova Calcium).

Mixing the product with Magnesium based products (e.g. Select Mag-S, Select MagPhos and Select Quick-Mg) needs extra caution! Their compatibility is depending on ph and water quality! Before mix them in large quantities, a small test is required!

Recommended dilution rate, for stock solutions = 15 kg / 100 liter water

Agronomical Advantages

1. High in phosphorus and nitrogen content
2. Can be easily mixed with single or compound fertilizers
3. Ensures quick start of the crop
4. Is the right source of phosphorus at flower initiation
5. Ideal P source for alkaline soils
6. Do not mix Select MAP with Ca / Mg in 1 tank

1. Select MAP has a high nutrient content in both phosphorus (P2O5) and nitrogen (NH4). The product is an ideal base for a fertigation program. Select MAP can be used as the sole phosphorus-source for the complete crop cycle.

2. Usually Select MAP is used in combination with single fertigation fertilizers like Nova ferti-K or other single fertilizers like ammonium nitrate or urea. By varying the rate of Select MAP in the solution the right balance between nitrogen, phosphorus and potassium is obtained.

3. Select MAP is especially suitable in the growth period when root establishment needs to take place. Sufficient phosphorus supply for transplants and crops that have to create a root system is crucial for a good start. Select MAP is the product to perfectly start production.

4. The phosphorus in Select MAP can also be used to prevent fruits from aborting fruits e.g. in melon. Sufficient P-supply is crucial in this stage. Select MAP can be included in the fertilizer program to initiate flowering so the need for phosphorus in the flower development stage is fulfilled.

5. The pH of Select MAP is 4,5 (at a 1%solution) it therefore acidifies the substrate on which it is grown. This makes Select MAP the ideal phosphorus fertilizer in alkaline soil situations.

6. Do not mix Select MAP with calcium (Ca) and magnesium (Mg) fertilizers. To avoid precipitation dissolve Select MAP in a different tank. Dissolve Calcium or Magnesium products in a different tank.

Select MAP 12-61-0, monoammonium phosphate is ideal for use in the initial growth phase of all crops, immediately before and after seeding and planting/transplanting.
