| contents | <p>This study was conducted to evaluate aggregate stability and hydraulic conductivity ofsoils derived from freshwater alluvium (FWA), coastal plain sand (CPS) and sandstone(SDS) in Akwa Ibom State, South-South Nigeria. Seventy-two core and composite soilsamples obtained at 0 – 20 cm and 20 – 40 cm depths from six locations representing theparent materials were analyzed by standard methods to determine their physical/ chemicalproperties, mean weight diameter (MWD), microaggregate stability and Ksat. Resultsshowed FWA/SDS soils were sandy loam and sandy clay loam, while CPS soils wereloamy sand and sandy loam at 0 – 20 cm and 20 – 40 cm depths respectively. Bulk densities3(1.42 – 1.58 g/cm ) were all low; organic matter (1.21 – 1.99%) was low in CPS/SDS soils,but high (3.10 – 4.02%) in FWA soils. Average MWD values for FWA, SDS and CPS soilsat 0 – 20 cm sampling depth were 0.349, 0.184 and 0.180 mm; whereas they were 0.288,0.221 and 0.271 mm at 20 – 40 cm depth respectively. Average clay dispersion ratios forFWA, CPS and SDS soils at 0 – 20 cm depth were 27.97, 28.51 and 29.16%; whereas theywere 26.13, 26.95 and 28.19% at 20 – 40 cm depth respectively. Average Ksat values forFWA, CPS and SDS soils at 0 – 20 cm depth were 25.27, 30.49 and 26.01 cm/hr; whereasthey were 16.36, 17.50 and 16.94 cm/hr at 0 - 40 cm depth respectively. Regularapplications of manure and adoption of other conservation measures were recommended.</p> |
