Dipotassium phosphate is a water soluble fertilizer and is used as a source of potassium and phosphorus.
Potassium plays an important role in the opening and closing of the stomata, which regulates the moisture balance of the plant. It also ensures the firmness of the plant cell. Avoid potassium deficiency at all times.
Phosphorus is also administered to the plant when using this fertilizer. Phosphorus is important for energy transport in the cell and in the formation of buds, flowers and seeds. It also stimulates root growth and is a building block for cell walls.
