Kevin wrote, "That's too bad. Rock phosphate is more slowly available than the others. That's why it's so good. It doesn't leach out of the soil the way the others do. If you have a rich, biologically active soil, it should be available to the plants shortly after it is applied. If you have dead, chemically burned soils, it may never become available."
 
Phosphorus doesn't hardly leach at all- even tripple superphosphate, but quickly forms nearly insoluble precipitates with other minerals becoming mostly unavailable to plants when applied to the soil.  Where phosphorous pollutes water is when the soil itself erodes into the water.   Anyway, that's how I understand it. As a fruit grower and a gardener I have never experienced phosphorous deficiency.  Hooray for our fungus friends.
