| Authors: | M.Y. Tayel, O.A. El-Hady |
| Abstract:
A laboratory experiment was conducted to study the effect of Super Gel on some soil - water relations. A surface sample from Tahrir sandy soil was treated with different concentrations of Super Gel (0.0, 0.05, 0.10, 0.15, and 0.20%). Whereas, the gel increased the total porosity, the micro pores relative to the total or the macro ones, void ratio, water holding pores, water retention, available water, and hydraulic resistivity, it decreased soil bulk density, quickly drained pores, hydraulic conductivity, mean pore diameter, intrinsic permeability, transmissivity and evaporation. From the economic point of view, such product can not be recommended for application on a field scale without visibility study for every case. | |
