Results and discussion

Applicant's summary and conclusion

Conclusions:
Inorganic phosphates are retained by most soils in “fixed” forms. Very little phosphorus is lost by leaching. The largest losses occur in sandy soils, which have both low capacity to retain water and low buffer capacity for the phosphate. The main way in which phosphorus originating in fertilizers may reach natural water is through surface runoff and erosion of the soil. These losses are normally small.
