Mono Potassium Phosphate (MKP) does not contain any elements such as chlorine, sodium or other heavy metals; hence it can be safely used with all kinds of plants. It is best used when the plant is about to flower. It enhances the fruit growth and increases the quality of any field crop. Mono Potassium Phosphate is well suited for application to the leaves and it has been proven to be a good protection in the control of fungus related diseases.
Water soluble Phosphates (as P2O5) by weight-52%
Water soluble Potash (as K2O)) by weight-34%
1. It is fully soluble fertilizer in water. It can be used for both i.e. For fertigation & foliar spray as it supplies P and K at crop growth stages. When Nitrogen is not required. 2. It is compatible with most of the commonly used insecticides fungicides except Bordo and plant growth providers / regulators. 3. It has proven for its effects on fungal diseases control (i.e Powdery/midew ) example on Grape, Cucurbits Mangoes, Roses etc. 4. Due to its buffer action at 4.5 M K P increases life of insecticides.
It has the highest number of macro elements which makes it a significant item for any farmer. Solubility is another reason that makes it useful to mix with other fertilizers. It does not have any nitrogen. This allows compatibility with plant development at various stages. When it is used with urea and ammonia, it keeps lowers the pH level. The dosage required is about 5-6 grams per liter. In the different stages of the growth cycle of the plants, it is a good source of strength. It can be used with pesticides in the farm. It should not be mixed with any fertilizers which contain calcium.
In Hydroponics and greenhouse trade it is a staple product. Since it is water-soluble its most useful application is for growing flowers. It is best for agriculture and buying from a quality trader is recommended. Its storage instructions should be followed for best results. In crops that are sugar rich, the application is ideal. As a foliar spray, it acts as a protection from mildew which may damage the flowering capacity.
