Soil physical properties were measured on field runoff plots established on a tropical Alfisol in Western Nigeria. Evolution of soil physical properties was assessed over a period of 6 years beginning in 1982 (when soil was cleared offits secondary regrowth) till 1987. Changes in soil physical prope

Soil infiltrability was evaluated once a year for five consecutive years in a longterm agroforestry experiment established on an Alfisol in western Nigeria. There were 6 treatments involving plow-till, no-till, contour hedges of Leueaena Leueocephala and Glirieidia sepium established every 4-and 2-m

Effects of three agroforestry systems were evaluated on changes in soil chemical properties over a period of 12 consecutive crops of maize-cowpea rotation grown on a tropical Alfisol in southwestern Nigeria. Measurements of soil chemical properties for 0-5 cm depths were made over a period of 5 cons
