In general, high rates of fertilizers and/or agro-industrial
residues containing P are usually applied to the soil with the
aim of increasing crop production.
This practice, however, can saturate binding sites in P soil particles
and result in a reduction of the capability of the soil to retain P. In
soils with low P retention potential, there is high likelihood of
release the P into the soil solution, and the element could reach
aquatic environments through runoff or drainage water
