Rock Phosphate Fertilizer
Commercial fertilizer it is mostly soluble P (in the form of phosphate). Within 24 hours this soluble P starts being converted to labile P and eventually to stable P. What this means is that most of the phosphorus fertilizer you add to the soil is available to plants for a short period of time, and then it gets locked away in the soil.
