Direct application of phosphate rock (DAPR) is an alternative fertilization option as major
source of phosphorus is phosphate rock (PR) that can contribute to sustainable intensification
of agriculture, particularly in developing countries with suitable PR resource .
DAPR should be finely ground and should be incorporated in the soil to promote dissolution.
Fine grinding leads to coverage of more surface area and higher solubility. Potential users
should be aware that DAPR must be applied way in advance before planting since it is slowly
