TL;DR: Alley cropping with the four woody species showed no effect on population of parasitic nematodes and maintained higher soil organic carbon, phosphorus and potassium levels, and Gliricidia and Leucaena showed higher nutrient yields than Alchornea and Dactyladenia.

TL;DR: The potential of planted leguminous cover crop fallow as an alternative to the natural regrowth fallow for sustaining the productivity of low activity clay (LAC) soils in the tropics as the fallow period shortens was tested at Ibadan in the forest-savanna zone of southwestern Nigeria.

TL;DR: A 3-year trial was conducted near Ibadan, southwestern Nigeria to measure the N contribution of 13 legume cover crops as compared to urea –N, using a N fertilizer replacement index for a maize test crop, finding that cover crops accumulated more N in the wetter than in the drier year.

TL;DR: It can be concluded from this study that in transforming shifting cultivation to a permanent cropping, fallow with natural vegetation, herbaceous legumes, cover crop fallow and woody legumes can contribute to the maintenance of crop production and soil fertility, however, length of fallow period does not need to exceed 2 years.

TL;DR: In this article, a decomposition equation that could be used to predict the decomposition rate of plant residues with various qualities across agro-eco-zones in West Africa was obtained from a field litterbag study conducted in the 2000 rainy season and the 2000/2001 dry season along the transect of West African major agroecological zones (agro-cooperative zones).
