1. It is an efficient source of phosphorus.
2. It 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.
As fertilisation actually depends on various factors besides the plant itself (local soil and environmental conditions). For more information please send your inquiry to us, our crop specialists are available to create customizes fertilisation schemes.
