A longterm experiment was conducted on Alfisols at Ibadan, Nigeria, to assess agricultural productivity and sustainability of different farming systems. The experiment, conducted for a 10 year period from 1979 to 1988, was implemented in two phases. The effects of methods of land clearing on crop...

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...

Soil erosion, measured in field runoff plots, was correlated with several rainfall erosivity indices. Erosion was measured on field plots established on a Typic Paleudult in southeastern Nigeria. Several erosivity indices were computed from a daily recording rain gauge sited in vicinity of the ru...

The effects of four gravel concentrations (0, 20, 40, and 60 percent by weight) and three gravel size fractions (4-8 mm, 8-15 mm, and 15-40 mm) on the calibration of a neutron moisture meter and density probe was investigated for a beach sand and a clayey tropical Alfisol (Oxic Paleustalf). The s...
