assessment of indirect methods to estimate soil hydraulic properties for simulating soil moisture in a sandy loam soil
soil hydraulic properties are key soil physical characteristics that are required to conduct soil and water related studies such as irrigation and drainage. in this study, three indirect methods: inverse modeling, pedo-transfer function, and the semi-physical method of arya et al., were compared in a sandy loam soil to estimate soil moisture retention and unsaturated hydraulic conductivity curv...
متن کاملQuantifying hysteresis of atrazine desorption from a sandy loam soil.
Batch experiments were carried out to investigate the effects of initial atrazine concentrations and consecutive desorption steps on the desorption characteristics of atrazine from a sandy loam soil. As initial atrazine concentration increased, the average percentage of atrazine desorption on the sandy loam soil ranged gradually from 23.1% to 38.5% after five consecutive desorption steps. The v...
متن کاملImpact of Distillery Effluent and Salts on Hydraulic Conductivity of a Sandy Loam Soil
Irrigation with distillery effluent, besides influencing crop yield, may have considerable impact on physical properties of soil because of its high salt and organic carbon contents. This experimental study was conducted to evaluate the effect of distillery effluent on hydraulic conductivity of a sandy loam alluvial soil and compare the effect of inorganic salts of potassium (K) with that of di...
متن کاملAssessment of chromium fixation capacity of sandy loam soil
The adsorption of chromium species in soils has received much attention because of its toxicity and bioavailabilities, which are adsorption depended. There are very little studies on adsorption of chromium in sandy loam soil. Hence, this paper presents the Cr adsorption capacity of sandy loam soil under chromium spiked condition. A batch technique was used to perform cr adsorption studies. Soil...
متن کاملResidual Soil Nitrogen and Nitrogen Response of Corn on Sandy Loam Soil
Groundwater contamination is an ever-increasing concern on a national level as well as locally. Increasing amounts of nitrate-nitrogen (NO3-N) being delivered by rivers, including the Mississippi, have resulted in an oxygen-depleted area or hypoxic zone in the Gulf of Mexico. (Turner and Rabalais, 1994b). This nutrient loading has caused nitrogen-limited phytoplankton to bloom. Decom-position o...
