Abstract
In order to investigate the role corn cobs and gypsum in some physical characters and organic matter of clayey cracks and their properties. Seven soils sites (Afak, Al-Diwaniyah, Al-Taleea, Babel, Agriculture college, Al-Wahda and Al-Raid project) There are three types of treatments as follows: - Corn cobs was applied in four levels (0 . 10 . 20 and 40) g.kg-1 - Gypsum (calcium sulfate) applied in four levels (0 , 5 , 7.5 and 10) g.kg-1. - Treatments of interaction between corn cobs and gypsum. Corn cobs , gypsum and their interaction were applied in same levels above. In this experiment , 2 kg of each studied soil were treated with same levels of corn cobs and gypsum above and incubated at 30 + 2 °C for 90 days and 80% relative moisture content at 33 kpa. The results were summarized as : Soil aggregate stability (MWD) and organic matter values were increased , while modules of rupture and (COLE) values were decreased , with increasing of gypsum and corn cobs applying. Also, results showed that the decreasing of (COLE) values were depending on the clay content and interaction treatments , between corn cobs and gypsum. The decreasing of (COLE) values were the highest in the clayey cracks disappeared treatments. ً.
