Soil erodibility measurements using field runoff plots were made for three contrasting soils in Nigeria. Field experiments were conducted over a period of 3 years from 1980 to 1983. The soil at Onne in eastern Nigeria is developed on coastal sediments and is classified as a paleudult. The soil at...
1984Des mesures d'érodibilité du sol ont été faitespour trois sols différents du Nigeria, sur des petitesparcelles d'érosion. Ces expériences au champs ont étéconduites sur une période de trois ans, de 1980 à 1983.Le sol à Onne dans l'est du Nigeria est dérivé desédiments marins et classifié "pal...

Agricultural soils, having been depleted of much of their native carbon stocks, have a significant CO2 sink capacity. Global estimates of this sink capacity are in the order of 20-30 Pg C over the next 50-100 years .Management practices to build up soil C must increase the input of organic matter...

Land clearing of a tropical rainforest implies cutting and felling of existing vegetation by manual or mechanized techniques, with or without windrowing, followed by burning in situ or in windrows. The objective of this study was to evaluate effects of land clearing at three levels of initial soi...

The effect of mulching on maize yield was investigated for luvisol and cambisol tropical soils during 1970–72. The increase in grain yield by mulching was 46, 52 and 22 per cent respectively, for 1970, 1971 and 1972. Mulched plants had higher growth rate and vigour and chlorotic symptoms of nutri...

The objective of this experiment was to evaluate the effects of growing a deep-rooting perennial on the root system development of a subsequent crop with low root penetrating ability. These effects were measured on a gravelly Alfisol with a compacted subsoil horizon for three tillage methods (zer...
