تأثير استخدام بعض المنتجات النفطية في المحتوى الرطوبي والملوحة لتربة جبسية .

Abstract

The experiment was conducted to evaluate the effect of some oil products on some soil properties for gypsiferous soil. Soil samples were collected from Dour region, Salah Aldeen governorate. Tow treatment including Flin coot, used crankcase oil cars and with out oil treatment were used in this study three methods were used to applied these treatment at 15 cm depth below soil surface, 30 cm and mixing with soil. Randomized complete block design with three replication were used in this experiment. The result showed a significant effect on soil properties increasing soil water content. Decreasing soil bulk density and increasing soil electrical conductivity were attributed to oil products comparing with control treatment. The best way of added oil products was as a layer under (30 cm) below the soil surface. The quality and efficiency of oil products were decreasing during the time.
