Abstract
The experiment was conducted at Khartoum New International Airport (KNIA), 40 kilometers south of Omdurman during 2010-2011 and 2011-2012 rainy seasons in an area of 5 hectares. Five water harvesting techniques namely, semi- circular water traps, V-shaped water dikes, pits, deep ditches and land without water harvesting technique were used. Soil analysis was also carried out including soil pH, electrical conductivity (E.C.), Ca++, Mg++, sodium (Na+) contents and sodium adsorption ratio (SAR).The results showed that, with the exception of control and V-shape treatments in the first season and semi-circular, deep ditch and V-shape treatments in the second season, soil pH after rainfall was significantly higher than before rainfall. For Ec, with the exception of semi-circular, pits and deep ditch treatments in the first season, E.C. was significantly higher before rainfall as compared to after rainfall. Except the control and V-shape in the first season and control and deep ditch in the second season, Ca+Mg, Na+ contents and SAR were significantly lower after rainfall as compared to that before rainfall in both seasons.
