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. The study, ...

Earthworm populations (predominantly Hyperiodrilus africanus and Eudrilus eugeniae) were sampled monthly for 1 yr during 1994 and 1995 in natural regrowth vegetation fallow (dominated by the natural fallow shrub Chromolaena odorata L.), planted fallow (the woody species Senna siamea Lam., Leucaen...

An experiment was conducted in 1990 and 1991 at the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria to study the role of earthworms in the decomposition of plant residue mulches with different qualities. Five mulches of Dactyladenia barteri, Gliricidia sepium, Leucaena leu...

An experiment was conducted to assess the N availability of roots of woody species and maize. The trial was conducted using a split-plot design with four replications. Four incubation periods (0, 2, 4 and 6 months) made up the main plots. There were six subplots, consisting of addition of fine ro...

Field litterbag decomposition study, through widely accepted for examining decomposition of plant residues, is time consuming, as it requires several months to complete. An experiment was conducted to explore the possibility to introduce ruminant nylonbag assay which only takes 3-4 days, to plant...
