this research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. this experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of chenran township. the results ...

A six-channel system was used to determine how differences of Henry’s law constant and vertical water velocity affect the diffusive loss of contaminants from a sandy soil. Two channels (10 cm wide x 110 cm long x 65 cm deep) were each fed with methyl tert-butyl ether, dichloromethane, or trichloroethylene in groundwater. After steady state was attained, vertical concentration gradients were mea...

The major objective is to expand upon the scientific knowledge regarding the changes in montmorillonite internal pore structure (air/water voids in the entire soil volume) and redistribution of water after treatment with EcSS 3000 soil stabilizer. The actual profile of water released on heating rather than determining the weight losses was used. An advantage of this procedure is that the result...

Termites are the most important soil fauna in the Sahelian zone of Africa, intensely interacting with the soil. Both the biotic and abiotic state of the soil affect the termite population and activity. The construction by termites of nests, gallery systems or sheetings from soil or from a mixture of soil and other material within the soil horizons or on the soil surface affect the physical and ...

one of the important aspects of soil is, knowing the relationships between spatial features of soil and quantity in statistical model. the goal of this research is to estimate saturated hydraulic conductivity by regression and co-active neuro-fuzzy inference system (anfis) with using the parameters of bulk density, real density, porosity, fractal dimension of particle size, and clay percent, si...

The aim of this paper was to study the variations of the electrical properties like electrical conductivity and dielectric constant of soils with their physical properties. Eight soil samples were collected from different locations of Coimbatore (Tamilnadu) at the depth of 0 – 15 cm. Soil samples were analysed for physical properties like texture, bulk density and porosity. The electrical condu...

We collected and analyzed breakthrough curve (BTC) data to identify the parameters controlling transport from a series of undisturbed fully saturated soil cores and a field test at the Shale Hills Critical Zone Observatory in central Pennsylvania. The soil cores were collected in a continuous hole extending across the soil profile vertically at one location to quantify how solute transport beha...
