| Zusammenfassung: | The invention discloses a method for using waste ion exchange resin ball to test soil available phosphorus, which comprises (1) regenerating waste ion exchange resin ball, (2) using lab assay method or using field in-situ assay method, (3) taking and washing the resin ball via some deionized water, eluting two times via alcaine solution at 0.5mol/L density, collecting all eluent, (4) using general molybdenum-antimony anti-colorimetry to test the phosphorus density in the eluent. The inventive method has low cost, simple operation and accurate test result. |
