تأثير تطبيق تقنيات نظم الحصاد المائي للمستجمعات الصغيرة في التوزيع الرطوبي للتربة

الملخص EN

The application of water harvesting systems on-farm system, which represents the microcatchment of rainwater harvesting systems which is being established on a large scale as one of the solutions to facing the water deficit crisis in the arid and semi-arid regions .

The field study was carried out for the purpose of studying the role of contour ridges , semi-circular ridges , and V-shaped ridges systems in soil moisture conservation .

The moisture content of the target area was measured at the two depths ( 20 and 40 cm ) .

The results showed the significant superiority of all treatments of water harvesting systems on soil moisture content compared to the control treatment, with a clear preference for the V-Shape treatment , As this treatment did not show a clear significant superiority between it and the treatment of semi-circular ridges .

It was also found that there are high significant differences in the moisture content at the 40 cm depth for all treatments
