Granular Rock PhosPhate ( G- R P )

GERP

-(GRP) decrease dust during using operation as it have very low dust existing less than 5%.
-(GRP) is produced from (- 100 Mesh grinded Rock Phosphate).
-According to Standard RP testing Size Phosphate with water mean that you can obtain the maximum solubility in soil
-Excellent P source to be Blended easily with other granular fertilizers.
-Our GRP heavy metals is Very low.
