Effect of pH on Saturated Hydraulic Conductivity and Soil Dispersion
The adverse effects of exchangeable sodium on soil hydraulic conductivity (K) are well known, but at present only sodicity and total electrolyte concentration are used in evaluating irrigation water suitability. In arid areas, high sodicity is often associated with high dissolved carbonate and thus high pH, but in humid areas high sodicity may be associated with low pH. To evaluate the effect o...
متن کاملChanges of the Saturated Hydraulic Conductivity of Soil Influenced and Exchangeable Sodium Percentage (%ESP)
Sodic soil is one of the most common problems of limiting agricultural production that related on irrigation. Saturated hydraulic conductivity is one of hydrodynamic characteristics in evaluating transmission flow through underground levels. To investigate the role of increment of exchangeable sodium in hydraulic conductivity changes (as characterized by the mobility of water in soil) an experi...
متن کاملSoil saturated hydraulic conductivity assessment from expert evaluation of field characteristics using an ordered logistic regression model
The knowledge of the soil saturated hydraulic conductivity (Ks) is essential for irrigation management purposes and for hydrological modelling. Several attempts have been done to estimate Ks in base of a number of soil parameters. However, a reliable enough model for qualitative Ks estimation based on the expert assessment of field characteristics had not been developed up to date. Five field c...

متن کاملSoil Pore Characteristics, Hydraulic Conductivity and Soil Bulk Density as Influenced by Agroforestry and Grass Buffer Conservation Practices
Despite improvements in the use of soil conservation practices, crop rotation and nutrient management programs, significant concern still exists regarding soil erosion and nutrient losses in runoff from row crop production. In the US, states are required to implement water quality standards based on USEPA guidelines or other scientifically defensible methods (Ice and Binkley, 2003). Agroforestr...
