Phosphorus When You Need It!

Mineral Development Fertilizer, soft rock fertilizer supplier, is an OMRI certified leader in organic fertilizer. MDF Mineral Grow is a calphos soft rock phosphate, also commonly called colloidal soft rock phosphate, organic fertilizer that provides a long-term approach to amending soil for phosphates. This high-phosphate, low-cadmium organic fertilizer offers immediately available phosphorus as well as a steady, constant supply of residual phosphorus over a number of years verses the typical approach of a single application of the acid phosphates. In many crops, the majority of the initial chemical phosphate application is unavailable when it is needed most, but this is not the case with MDF Mineral Grow colloidal phosphate.

A key benefit to colloidal soft rock phosphate over the chemical phosphates is the colloidal component. This form of phosphate is available immediately, the phosphate, calcium, and trace elements are complexed into the clay colloid, therefore, they will never lock-up and they are also available for a time released period of 8 to 10 years, or as the plant needs them. MDF Mineral Grow is is a mineral-dense calphos fertilizer and is much more than just a phosphate source. Most significantly, It contains high levels of silica, which is another element that should be mentioned for all of its many positive benefits. 

MDF Mineral Grow adheres to and becomes part of the soil. It will not leach or revert, and once applied it remains in the soil until used by the plants making it safe to use in run-off areas.
