The effect of micro water harvesting techniques on soil moisture in eroded soils of the arid zones in Showak Area (Sudan)‎

الملخص EN

The study was conducted at Showak area during season 1999 / 2000.

U shaped and L shaped water micro catchment treatment was compared with a control.

Seedlings from six tree species were tested.

They are Acacia tortilis subspp.radiana, Acacia mellifea, Acacia seyal, Zizyphus spina-christi, Balanites aegyptiaca and Moringa oleifera.

Gravimetric moisture content was determined after the rainy season.

Results indicated that the U shaped micro-catchments increased soil moisture content to an average of 17.

9 % compared to 13.

1% for control.

The survival rate percent had increased in the micro catchments for all tree species.
