Porosity variabilities along a forest – grassland mosaic in Ibeku, Abia State, Nigeria

Abstract

Variation existed in the porosity characteristics of pedons located on forestland and grassland. Percent coefficient of variation (CV) was greater in forest soils for both bulk density and porosity (% CV = 29.99 and 13.2) than as found in grassland soils (% CV = 2.6 and. 4.1). These results were explained by wide variations in percent organic matter content existing between the two groups of pedons. While percent coefficient of variation for forest soil was 130.1 that of grassland gave 61.4.
