We can proudly say that PROM was created and developed in our city UDAIPUR in Rajasthan which also has the best Phosphate mines of the country. The advantage of PROM is that the dissolution of Phosphorus in the ground is slow, and the results are good for two consecutive crops. It also contains organic matter that helps in many ways like retention of moisture, microbial activity. In saline soil, even the DAP fertilizer fails but PROM is very effective as it contains organic carbon element and also humic acid having electrical conductivity. PROM is an ideal soil conditioner, retains moisture, improves porosity of soil, promotes root growth and increases the absorption rate of nutrients in soil.
