Soft Rock Phosphate
Soft rock phosphate is found in the clay layers surrounding hard rock phosphate deposits It is 20% total phosphate, 3% is readily available, the remaining 17% is released by microbial activity. .
The key to soft rock phosphate's effectiveness as a fertilizer/soil amendment is that the phosphate and multitude of other minerals in it are in the colloidal form, including 20% readily available calcium.
Colloids do not dissolve in water but are suspended in it. They stay close to the surface, suspended in water, preventing their loss through being leached out of the soil.
In this colloidal form it does not combine with other elements so it stays available for plants to use as needed.
Minerals in this colloidal form easily enter the plant and are efficiently utilized.
Colloidal phosphate is also electrochemical so it is capable of holding onto other minerals retaining them in the root zone. Application of soft rock phosphate followed by lime onto a soil that has high levels of carbon through the decomposition of organic matter will produce conditions beneficial for good; aeration, microbial growth, nutrient retention and energy flow in your growing beds.
Being an electrochemical colloid soft rock phosphate will influence water in the root zone and in the plant. Albert Popp showed that such colloids influence the structure of water allowing for more efficient transport of energy and matter in an organism.
