Abstract
ABSTRACT Astudy was conducted to investigate the influence of surface treatments on evaporation from a sandy soil. Four treatments were included: Control, 0.5 kg/m2 of solid manure (applied in liquid form), 1% polyvinyl alcohol (2 L/m2), and 1% polyvinyl acetate (2 L/m2) applied to the surface of soil columns. Evaporation was measured in a controlled chamber. The results indicate that liquid dairy cattle manure is the most effective for reducing evaporation followed by polyvinyl acetate and polyvinyl alcohol. All materials used in the experiment increased the liquid-soil contact angle, decreased the unsaturated hydraulic conductivity and decreased the penetration coefficient. Manure and polyvinyl alcohol increased the saturated hydraulic conductivity, whereas polyvinyl acetate decreased it. The magnitude of the evaporation reduction is attributed to the infuence of the different materials on these parameters.
