Robert E. Sojka mainly investigates Polyacrylamide, Irrigation, Surface runoff, Surface irrigation and Soil water. His Irrigation research includes elements of Infiltration, Erosion control, Environmental engineering and Animal science. His Animal science research is multidisciplinary, relying on both Calciorthid, Loam and Infiltrometer.
His study ties his expertise on Agronomy together with the subject of Surface runoff. His Agronomy research is multidisciplinary, incorporating elements of Water quality and Water pollution. His Soil water research integrates issues from Organic matter, Aggregate and Water content.
His primary scientific interests are in Irrigation, Agronomy, Soil water, Surface runoff and Surface irrigation. Robert E. Sojka integrates several fields in his works, including Irrigation and Polyacrylamide. The concepts of his Agronomy study are interwoven with issues in Coastal plain and Nutrient.
His Soil water research incorporates themes from Environmental chemistry, Leachate and Organic matter. The study incorporates disciplines such as Infiltration and Erosion in addition to Surface runoff. In his study, Animal science is strongly linked to Loam, which falls under the umbrella field of Surface irrigation.
His scientific interests lie mostly in Soil water, Irrigation, Agronomy, Infiltration and Surface runoff. His work deals with themes such as Environmental chemistry, Total organic carbon, Composite material, Aggregate and Tillage, which intersect with Soil water. His Irrigation study combines topics in areas such as Water quality, Environmental engineering, Erosion and Agricultural crops.
His study in Agronomy is interdisciplinary in nature, drawing from both Ecology and Nutrient. His Infiltration study incorporates themes from Surface irrigation, Soil test and Water content. His Erosion control research extends to Surface runoff, which is thematically connected.
Robert E. Sojka mainly focuses on Agronomy, Surface runoff, Irrigation, Soil water and Infiltration. His Agronomy research is multidisciplinary, incorporating perspectives in Subsoil and Soil horizon. Robert E. Sojka combines subjects such as Surface irrigation and Environmental engineering with his study of Surface runoff.
His Surface irrigation study deals with Erosion control intersecting with Loam, Soil quality, Water content, Water conservation and Land management. The various areas that Robert E. Sojka examines in his Environmental engineering study include Soil stabilization, Biopolymer, Polymer, Ditch and Erosion. His studies in Soil water integrate themes in fields like Environmental chemistry, Coastal plain and Nutrient.
