Figure 2 - Effect of varying P sources in varying soil layers on the availability of phosphorus extracted by the A) Mehlich-1 (P- M1), B) ion exchange resin (P-IER) and C)

The aim of this study was to evaluate the effect of humic acid carbon concentrations on the P contents extracted by the mixed resin extractant and by the Bray- 1, Mehlich-1,

Phosphorus contents determined after extraction with anionic resin (AR), mixed resin (MR) and Mehlich-1 (M1) in Latosols samples treated with P sources and levels, after

the highly significant correlations observed between the contents of total Ca and P extracted by Mehlich-1 (M-1) and by ion-exchange resin (IER) indicate pronounced influence of

The objective of this work was to evaluate remaining P, compared with soil clay content, as a P buffer index to classify P extracted by the Mehlich-1 (M1) and Mehlich-3 (M3)
