The Zona da Mata region of Minas Gerais, Brazil, is characterized by mountainous topography, the presence of low fertility, highly acidic red-yellow latosols, and the predominance of naturalized pastures of molasses grass (Melinis minutiflora). In studies carried out in the area, Cratylia argente...

We conducted field experiments over 2 years on two acid soils of southern Cameroon to test whether efficient uptake and use of phosphorus (P) from less available sources by grain legume genotypes could benefit subsequent rotational maize. We grew two crops each year. For the first crop we grew 4 ...

Phosphorus (P) uptake by plant roots depends on P intensity (I) and P quantity (Q) in the soil. The relative importance of Q and I on P uptake is unknown for soils with large P sorption capacities because of difficulties in determining trace levels of P in the soil solution. We applied a new isot...
