Abstract/Contents: | "Various soil tests are used to estimate phosphorus (P) availability for both crop uptake and potential loss to water. Conversion equations may provide a basis for comparison between different tests and regions, although the extent to which information can be interchanged is uncertain. The objective was to determine and quantify relationships between specific soil test extractants for samples taken annually in October and February over 4 years from four sites in each of eight soil series under grassland. The extractants comprised Mehlich-3, Morgan, Olsen, Bray-1, lactate-acetate, CaCl2 (1:2 and 1:10 soil solution ratios), and resin. The results showed distinct relationships for each soil series, for which individual lines regression models (different intercepts and slopes) were superior to a single conversion equation across all soils. The ensuing difference between soils was large and ranged from 1.9 to 8.0 and 9.2 to 15.6 mg kg-1 P for Morgan and Olsen, respectively, at 20 mg kg-1 Mehlich-3 P. Generally, the environmentally oriented tests CaCl2 and resin correlated best with Morgan. Some soil-specific limitations were also observed. CaCl2 was less efficient than Morgan, and Morgan less efficient than Mehlich-3 on a high Fe-P soil derived from Ordovician-shale diamicton, compared with the general trend for other soils. This finding suggests that further disparity may arise where evaluation of critical, or other, limits across regions involves even a limited sequence of tests." |
