Influence of Anionic Surfactant on Saturated Hydraulic Conductivity of Loamy Sand and Sandy Loam Soils
Surfactants released into the terrestrial environment in large amounts can potentially alter the physical, chemical and biological properties of soils, particularly the saturated hydraulic conductivity (Ks). Unfortunately findings regarding this process are quite limited. In this study, column tests were used to analyze the effects of Aerosol 22, a widely used anionic surfactant, on Ks of loamy...
متن کاملeffect of slope on soil wetting pattern under surface drip irrigation and simulation hydrus-2d model
in this study, effect of slope on soil wetting pattern under surface drip irrigation and simulation with hydrus-2d model evaluated.the physical model made of plexiglas to size 83, 6 and 54 cm (length, width, height) filled with silty clay loam soil was used. to achieve the desired discharge, a small drip irrigation system created that includes a water tank with a fixed height (about 2 meters), ...
متن کاملRespirable dust and quartz exposure from three South African farms with sandy, sandy loam, and clay soils.
OBJECTIVES To quantify personal time-weighted average respirable dust and quartz exposure on a sandy, a sandy loam, and a clay soil farm in the Free State and North West provinces of South Africa and to ascertain whether soil type is a determinant of exposure to respirable quartz. METHODS Three farms, located in the Free State and North West provinces of South Africa, had their soil type conf...
متن کاملImpact of Rotylenchulus reniformis on Cotton Yield as Affected by Soil Texture and Irrigation.
The effects of soil type, irrigation, and population density of Rotylenchulus reniformis on cotton were evaluated in a two-year microplot experiment. Six soil types, Fuquay sand, Norfolk sandy loam, Portsmouth loamy sand, Muck, Cecil sandy loam, and Cecil sandy clay, were arranged in randomized complete blocks with five replications. Each block had numerous plots previously inoculated with R. r...
متن کاملInfluence of Foliar Application with Micronutrients on Productivity of Three Sugar Beet Cultivars under Drip Irrigation in Sandy Soils
Two field experiments were conducted at the Desert Experimental Station of the Fac. of Agric., Cairo Univ. in Wadi El-Natroon, during 2012/2013 and 2013/2014 seasons to study the response of sugar beet yield and some of its attributes in three multigerm seed cultivars, viz. Heba, Ninagri and Halawa under drip irrigation in a split plot design to foliar application with zinc (Zn) + Manganese (Mn...
