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.

The world's phosphate ore reserve nearly totals 69.5 billion tons (2019), but its distribution is uneven, more than 80% of which is concentrated in North Africa.

However, the European Commission has recently put forth a proposal to classify phosphate rock as a critical mineral rather than a strategic one. This potential reclassification could potentially slow down the permitting process in Brussels, as critical discoveries are not eligible for the same expedited approvals granted to strategic ones.
