Abstract

The study examined changes in soil physico-chemical properties in fallow communities in the Rainforest Zone of Southern Nigeria. Fallow vegetation of 1-year, 3-year, 5-year and 10-year, were studied. The quadrat approach of sampling was employed to collect surface soil samples (0 – 15cm) from six plots of 10m x 10m across the four fallow communities. Results showed that the mean contents of organic matter (OM), total nitrogen (TN), effective cation exchange capacity (ECEC) and available phosphorus (Av. P) substantially increased in the 3-10 years fallows presumably due to the increase in litter accumulation following the establishment of woody vegetation. PCA result identified soil nutrient, soil acidity and particle size composition as soil properties that progressively changed across the fallow soils. The study suggested that farmers should be encouraged to allow woody trees on their farmlands to speedy up soil fertility restoration.
