Correlations between Bray 1, Bray 2 and ISFEI (Volume) soil-P extractants



Correlations between Bray 1, Bray 2 and ISFEI (Volume) soil-P extractants



Fertilizer Society of South Africa Journal (1): 13-18



Bray 2 gave much higher values than Bray 1 or ISFEI (vol) for alkaline soils and soil treated with sedimentary rock phosphate. For acid soils where no sedimentary rock phosphate had been added the P values obtained by Bray 1 and ISFEI (vol) were similar.
