Tree-root influence on soil physical conditions, seedling establishment and natural thinning of Acacia seyal var. seyal on clays of Central Sudan The effect of the tree roots on soil bulk density, soil moisture content and understorey vegetation was studied in the Central Clay Plains of the Sudan...
SUMBER: broome.soil.ncsu.edu/ssc012/Labs/4.ppt Definition Soil structure is the arrangement of the primary soil particles (sand, silt, and clay) and other soil materials into discrete aggregates. SUMBER: broome.soil.ncsu.edu/ssc012/Labs/4.ppt SUMBER: broome.soil.ncsu.edu/ssc012/La...
The assessment is based on the maximum of bulk density attained using the Proctor test (MBD). In this study the soil texture is expressed by silt plus clay (S + C) or clay (C). The relations between the soil texture and MBD, and between soil texture and critical water content (CWC—...
Soil particle density (rho(S)) is one of the basic physical properties of soils and represents an essential element of diverse pedotransfer functions (PTFs). Recent findings support a PTF where the solid soil particles were considered as a mass-based mixing ratio of two components, soil mineral...
Regression relationships between Db and soil properties indicated that Db can be accurately predicted (R2 > 0.60) from organic-C content for Inceptisols and Spodosols. Regression relationships with organic C and clay contents, water content at –1500 kPa, and the –1500 kPa water to...
SUMMARYThe relative importance of soil bulk density, water content and potential on the self-diffusion and impedance factors of 36C1 in a sandy loam and loamy clay were studied. The soil bulk densities used represented a range of conditions from freshly tilled seedbeds to compacted soils. The ...
We sampled the soil horizons of 40 important Belgian soil series, with textures ranging from sand to heavy clay, and measured their moisture retention characteristic (MRC). Of these horizons, the particle-size distribution in nine fracti... H Vereecken,J Maes,J Feyen,... - 《Soil Science》...
Infiltration measurements were made on swelling clay soil samples packed into columns. Small increases in bulk density over the range 1.10 to 1.25 g/cm3 markedly decreased the rate of water movement. The magnitude of the effect was greater for confined samples than unconfined samples at all initial...
