How to Use Rock Phosphate Fertilizer In Your Garden

2020-1-23  Using Soft Rock Phosphate Fertilizer Properly. Soft rock phosphate is insoluble if the pH of your soil is above 5.5. It needs acidic conditions to be fully absorbed by the plant roots. To use soft rock phosphate properly, always incorporate it into the soil before planting. You can also add it to a planting hole when repotting or planting trees.

Some notes OB the use of rock phosphate as a fertilizer.

Pot and field experiments with rock phosphates are reviewed. Three or four times as much rock phosphate as super was usually necessary to give the same result. Rock phosphate gave the best results where the soil was acid and not too poor in available P. Soft rock phosphates compared relatively well with super when the two carriers were top-dressed to grasslands and leys.
