Phosphorus migration analysis using synchrotron radiation in soil treated with Brazilian granular fertilizers

The aim of this study was to evaluate the phosphorus (P) mobility in a tropical Brazilian soil type red Oxisol treated with three different forms of granular fertilizer. Total Reflection X-Ray Fluorescence (TXRF) was applied to determine the concentration of P at different distances from granular fertilizer application point The results showed that most of the P from fertilizers tends to concentrate in a region of up to 10 mm around the place of the fertilizer deposition.
