Characterization of spatial distribution of soil organic carbon stocks in selected land use types and landscapes in Chama District
… grid survey of 10m by 10m was used to sample the soils in the top 20cm of the soil for all the land uses and landscapes, composite samples were made for each land use type that was replicated 5 times. The other parameters determined were soil texture and bulky density. The percentage SOC was …

Hydraulic properties of asphalt concrete
… models and laboratory methods common to soil analysis, to characterize the hydraulic properties of asphalt concrete. Wetting and drying water characteristic curves were measured for six asphalt concrete cores. From the water characteristic curves, it is proposed that asphalt concrete may …

The effects of moisture, cation concentration, temperature, density and composition of soils on their electrical resistivity
… so il s are examined using laboratory prepared soils. An i nexpen si ve method for preparing soils of different compositions was developed by mixing various size fractions i n the laboratory. Moisture and cation c oncentration are related to soil resistivity by powe r functions, whereas soil …
