Comparison of Soil Phosphorus Tests for Assessing Plant Availability of Phosphorus in an Ultisol Amended with Water-Soluble and Phosphate Rock Sources
This work reports on soil phosphorus (P) test calibrations in triple superphosphate (TSP)– and phosphate rock (PR)–fertilized soils for cost-effective fertilizer recommendations. Results showed that separate calibrations are required for TSP and PR fertilizers for conventional soil tests. Use of cri...
