Abstract

Low water stability of soil microaggregates accentuated by increased intensity of cultivation, high soil erodibility and climatic erosivity has become a major cause of increased water erosion process on agricultural lands in Imo Statea. Thus, this study was conducted in 2006 to quantify the effects of different land use types (LUTs) on the water stability of their various soil microaggregates in the area. Six LUTs [natural forest (NF); oil palm plantation (OPP); plantain plantation (PP); rubber plantation (RP); bush fallow (BF) and continuous cassava cropping (CCC)] were chosen for the study. The soil microaggregate stability was measured by clay dispersion ratio (CDR) and aggregated silt and clay, ASC (%) indices. Results showed that the CDR obtained from soil under NF LUT was significantly lower (implying higher microaggregate stability) than what were obtained from other LUT soils. Correlation of each of the microaggregate stability indices (CDR and ASC) with some soil properties suggested that organic matter (OM), calcium (Ca2+) and magnesium (Mg2+) might be the most important variables related to each of the indices
