نفذت التجربة بهدف تحسين كفاءة نظام الري بالتنقيط بالاعتماد على رطوبة التربة. و استخدم في التجربة مقياس غير مباشر لقياس الرطوبة موصول مع جهاز إشارة ( فاصل واصل ), و جهاز تحكم مبرمج على درجة رطوبة دنيا, و هي درجة السعة الحقلية للتربة و التي قيمتها ( 25%), و على درجة رطوبة عليا هي درجة الإشباع عند رطوبة (75%).
The experiment carried out to improve the efficiency of drip
irrigation system , based on soil moisture. The indirect measure of
humidity Was used in the experiment, connected with the pointing
device (separator continued), and a control device programmed on a
low humidity degree, which is degree the field capacity of the soil and
which value is 25%, and on a high moisture degree which is saturation degree
at 75%..
