“…Rabbi et al [44] mention that percentages of clay, bulk density, and porosity have a strong influence on Ks. These results are in agreement with Bardhan et al [45] who reported a decrease in the infiltration rate due to clogging of soil pores by suspended materials present in the treated wastewaters. Previous studies with similar soil texture (clay) of the current study reached the same conclusion that application of wastewater resulted in pore clogging, which leads to reduced soil porosity and subsequently a decrease in the soil infiltrability [46].…”

Our objective is to study interaction between physical and chemical properties of soils and their earthworm community characteristics in different areas irrigated by wastewaters and well waters. The fields have different topography and agricultural practices conditions and are located in two regions of Batna department (Eastern Algeria). Both regions are characterized by a semiarid climate with cold winters and Calcisol soils. Nine fields were subject of this study. Three of these fields are located in Ouled Si Slimane region whose irrigation is effectuated by natural waters of Kochbi effluent. The other six fields are located at edges of Wed El Gourzi, effluent from Batna city, and partially treated through water treatment station. The best rates of water saturation and infiltration as well as abundance of earthworms were recorded at sites characterized by irrigation with wastewaters downstream of El Gourzi effluent. PCA characterizes two major groups: a group of hydrodynamic infiltration parameters and structural index stability of soil, explained by fields irrigated with wastewaters downstream of El Gourzi effluent. This group includes chemical characteristics: pH and electric conductivity. The second group is the characteristics of earthworms and includes organic matter content, active limestone levels, and Shannon Biodiversity Index.

“…In fine grain soils, the hydraulic conductivity under saturated conditions is controlled by the microstructure of the soil matrix which in turn depends on the type of the fine materials (e.g., clay mineral) present in the soil, the composition of the exchangeable cations, and the electrolyte concentration in the pore water system (Ndiaye et al, 2007). It has long been recognized that hydraulic conductivity is related to the grain size distribution of granular porous media (Bardhan et al, 2016). Since hydraulic conductivity can vary, depending on many indices, it is difficult to treat all these parameters at the same time (Chaudhari et al, 2010).…”

“…When the outflow became constant and measured against time. The hydraulic conductivity was calculated by the Darcy's Law (Bardhan et al, 2016): Ks = Q ∆L / ∆H A T Where, Q= Volume of water passing through the soil in time, T (cc h -1 ) A= Cross sectional area of the soil (cm 2 ) L= Soil height (cm) H= Hydraulic head difference (cm) Ks= Saturated hydraulic conductivity (cm h -1 ) Statistical analysis: The data obtained were statistically analysed by using the Duncan's Multiple Range Test (DMRT), principal component analysis (PCA) and analysis of variance (Gomez and Gomez, 1984).…”

Three soil profiles from Regional Research Station of Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur situated in New Alluvial zone of Nadia district, West Bengal were studied to assess the predictability of the hydraulic conductivity of the soil as influenced by different physical and chemical and properties of cultivated and forest land. The various statistical procedures were employed on the measured laboratory based data for comprehensive agreement of dependent hydraulic conductivity of soils as a model function of independent soil variables that is likely to be useful for different land cover systems. Soils are neutral in reaction, silty clay to silty clay loam in nature. Forest soil contained greater organic carbon (OC)(5.9 ± 0.16 g kg ). Jhau plantation recorded the highest value (6.8 g kg -1) of OC due to soil texture and cation exchange capacity (CEC). Soil hydraulic conductivity was greater in soil for cabbage and Sagun tree among the cultivated and forest soil studied with values 2.80 and 1.10 cmh -1. Correlation study showed a positive and negative relation with hydraulic conductivity for sand (r= 0.68; P > 0.05) and clay (r= -0.71; P > 0.05) respectively. Further, principal component analysis concluded that addition of bulk density with clay and sand can predict the hydraulic conductivity for different land uses.

The soils of a 10-ha agricultural field in the municipality of Guasave, Sinaloa, were characterized through electrical measurements and determination of petrophysical parameters. An electrical profiling survey for AB/2 = 2 m and 3 m was carried out in the study area. The apparent resistivity, soil moisture, and pore water salinity values were recalculated into petrophysical values using the Petrowin software, resulting in fine (clay+silt) content, and porosity and hydraulic conductivity maps. Using the Bouyoucos method, soil texture was determined for 30 soil samples collected in points matched with EP measurement points. The results of textural analysis indicated that the study area is quite complex, with the presence of eight textures of soil, and soil moisture and groundwater salinity variable in twice and five times, respectively. The fines content values obtained from Petrowin software and the Bouyoucos method were compared showing a high correlation (R = 0.91), giving reliability to fast and inexpensive techniques such as electrical profiling for the determination of the soil petrophysical parameters in extensive agricultural land.
