Abstract

Polyvinyl acetate was used as a soil conditioner and applied into sandy loam soil by a field sprayer in West Nubaria. Five different concentrations of polyvinyl acetate (0, 0.5, 1, 1.5 and 2.0 %) and two working pressures 50 and 150 kPa. The differences of soil moisture content among the annual crop season were greater at the bottom layer than the upper layer. Increasing the concentrations of polyvinyl acetate led to more soil moisture content through the annual crop season. The moisture content values found under working pressure of 50kPa ranged between 5.55 to 20.75, 23.19 to 32.93 and 17.73 to 27.25% after 1^st irrigation, 2^nd irrigation and before harvesting respectively. Using the polyvinyl acetate concentration of 2.0% gave the highest value for water retention. The moisture content values found under working pressure of 150 kPa ranged between 5.55 to 22.82, 23.19 to 36.78 and 17.73 to 30.11% after 1^st irrigation, 2^nd irrigation and before harvesting respectively. Increasing the working pressures led to increase energy consumed which were 6.48 and 15.79 MJ/fed for working pressures 50 and 150 kPa respectively. The highest values of plant emergency ratio and crop yield were 87% and 7606 kg/fed under concentration of 2.0% and 150 kPa. The obtained results prove that using the polyvinyl acetate as a soil conditioner gave a good effect in sandy loam soils characteristics.
