Soil contamination in the corrals of the Bedouin herds at the Northern Negev. Tracing and analyzing the influences of sheep herds slops in soil.
Field observations have indicated the formation of horizontal, pipe shape cavities, along gully and dry stream channel banks in the semi-arid region of the northern Negev Desert, Israel. Piping is a well-known phenomenon in humid regions due to subsurface water flow and seepage weathering...
PAM - A new providing method of polyacrylamide (PAM) emolsion is tested in lab and field as a soil conditioning, and as a solution for low infiltration rate and extreme runoff issues in semi-arid areas.
LATEST RESEARCH:
Salt removal by soil manipulation. This work suggests that the manipulation of soil structure by changing the soil physical properties can enforce salt removal from the root zone and create preferable growth conditions.
A new application of gypsum is suggested, in a suspension, which allows it to be applied via drip irrigation, without precipitating in irrigation pipes and blocking the drippers.
This work explores the effect of a surfactant (H2flo) on hydrophobic soils. It is suggested that adding this surfactant to irrigation water may change wetting processes and decrease hydrophobicity.
The angle of slopes have a key role affecting sub-surface water flow, which determines the location of evaporation and salt accumulation.
This work explores the effect of slope inclination angle on salt distribution.
