Abstract AR
أجريت قياسات حقلية و تحليلات مختبرية لبيان تأثير خشونة السطح الناتجة من الحراثة الأولية بالتي السك و الجيزل على معدل فقد التربة حيث أجريت قياسات حقلية لارتفاعات الكتوف و تحليلات مختبرية لتجمعات التربة و مجاميع التربة غير القابلة للتعرية. أشارت النتائج إلى إن الكتوف و مجاميع التربة غير القابلة للتعرية لهما دور كبير في تقليل معدل الفقد الحاصل من سطح التربة و كان معدل الفقد الحاصل بعد الحراثة بالدسك أقل بالمقارنة بالفقد الحاصل بآلة الجيزل و جاءت نتائج التحليل الإحصائي متمشية مع نتائج التحليلات المختبرية و الحقلية.
Abstract EN
Field measurements and lab analysis were conducted to determine the effect of soil surface roughness (oriented and random) resulted from discing and chiseling on the soil loss by wind erosion.
Some soil ridges parameters were measured in the field and aggregation (clods and non-erodible aggregates) were determined in the lab.
The soil loss of the two operations was determined as a function of these variables.
The results showed that the large proportions of random roughness (large clods) and clear oriented roughness (soil ridges) in the tilled layer after soil discing have a greatest effect in reducing the amount of soil loss and potential erosivity of soil by wind action in comparison with soil chiseling.
This is attributed to the fact that the soil clods easily crushed into fine aggregates after soil chiseling but remained unchanged in soil discing.
The statistical analysis coming in agreement with the results of the lab and field investigation.
