A field study of cowpea, soybean and maize was made at Ibadan, Nigeria, to determine the uptake of mineral nutrients and quantities removed in crop residues and seed. Concentrations of N, the major cations (K, Ca, Mg and Na) and major anions (P, S and Cl), and the micronutrients (Fe, Mn, Zn and C...

Mineral nutrient uptake and removal by cowpea, soybean and maize cultivars in West Africa, and implications for carbon cycle effects on soil acidification
Information on the inter- and intra-specific variability in the acquisition and utilization of phosphorus (P) by promiscuous soybean genotypes under low-P conditions can be helpful in the short-term management of soil P availability. Thirteen promiscuous soybean genotypes were evaluated in a low-...

Phosphate rock utilization by soybean genotypes on a low-P savanna soil and the status of soil P fractions after a subsequent maize crop
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 benefits from grain-legume crops to subsequent maize grown on acid soils of southern Cameroon
There are several indications that legumes are capable of accessing sparingly soluble phosphorus (P) in the soil through root-induced processes. We hypothesize that this plant-induced mobilization of P can be demonstrated if the plant accessible P assessed by isotopic dilution ( L-value ) exceeds...

Two crop rotation cycles were evaluated to determine the effect of cropping systems and N
fertilization on the yield and efficiency of N in maize. Maize was grown on plots which had previously
supported monocrops of two genotypes each of soybean (TGx 1448-2E and SAMSOY-2) and cowpea
(IT 96D-724 a...
