Ten widely different plant species were compared for their ability to reduce soil mineral
nitrogen levels in the autumn and their ability to improve the nitrogen nutrition of the …

High rates of N fertilizers are often necessary to achieve yield goals in the humid tropics,
where subsoil acidity prevents deep crop rooting. However, leaching of fertilizer nitrate may …

Crop simulation models that accurately predict the availability of N from decomposing plant
residues would provide a powerful tool for evaluating legume green manures as potential N …

Abstract In the northern Guinea Savanna of Ghana (1984–1987) a field experiment was
conducted to study the reasons for beneficial effects of rotating maize (Zea mays) and …

Two varieties of soybean (Glycine mar (L.) Merr.) and a maize (Zea mays L.) control crop
were grown in replicated trials at 10 sites in the Guinea savana of Nigeria in 1993 followed …

The impact of deferred grazing (no defoliation of pastures for a period generally from spring
to autumn) and fertilizer application on plant population density, ground cover and soil …

The potential of legume green manure (GM) as an alternative to mineral N fertilizer in
tropical horticulture has received scant attention. The feasibility of meeting N needs of …

In the southern Great Plains, dryland double‐cropping soybean [Glycine max (L.) Merr.] after
