ABSTRACT Cover crops grown alone or in association can take up different amounts of phosphorus (P) from the soil and accumulate it in different P-forms in plant tissue. Cover crop residues with a higher content of readily decomposed forms may release

The natural grasslands in South America have soils with low phosphorus (P) availability (1.0 to 7.5 mg kg−1), possibly altering the absorption and accumulation of P in grasses. We evaluated the chemical fractionation of P in the leaves of the most

The application of slurry may reducing the bioavailability the aluminum (Al), by increasing the concentration of soluble ligands. The study aimed to assess how the long-term use of pig slurry is able to modify the exchangeable Al content, activity, a
