inputs and losses of phosphorus

Are there any other inputs of soil phosphorus other than fertilizers, primary and secondary minerals, human and animal residues and weathering? What about for losses, any other than runoff, erosion and leaching?

One more loss would be plant removal (harvesting).

Thanks

remember Phosphorus fixation too! it doesn't have to be eroded away to be considered a loss. it can stay in the soil profile but be unavailable to plants.

Thanks
