| Abstract | ||
| To study the effect of Sesbani (Sesbania exaltata) and Blady grass ((Imperata cylendrica L.) plants rizhisphere . Two sites were chosen the first site was taken the Sesbania plant and the second was taken the Blady grass plant , for every plant two samples were taken the first form the outside of rhizosphere and the second from rhizosphere in three replicates . The chemical , physical and mineralogical analysis were measured . The results showed : - The smectite , true chlorite , mica and kaolinite were showed in all samples in outside of rhizosphere in both plants. - The X-ray diffractions showed 15.6 angstrom in ethylene glygole treatments in the rhizhosphere soil in both plants and dis appeared in the heated treatment (350 and 550( centigrade and that mean the swelling chlorite were formed addition to the origin chlorite was found in the soil by the second and third diffractions (7.2 and 4.7) angstrom were singed to the true chloride and it's still fixed in all treatments . - The calcium was absorption in high quantities but Magnesium was low and that led to increase of magnesium ions in rizhosphere and Magnesium hydroxyl layers was formed as a result of alkali media of soils and the inter hydroxyl layer was formed and that lead to the swelling chlorite . - The potassium ion were absorption by roots in both plants and that led to release from inter | ||
