| Abstract | ||
| The effect of brucite precipitation on mineral properties,(2:1) clay minerals were investigated. The X-ray diffraction (XRD) indicates that a swelling chlorite mineral is a result of deposit Mg- hydroxyl interlayer (brucite) in montmorillonite along with vermiculite clay minerals. Release Mg ions from different minerals such as dolomite and gypsum, addition to common clay minerals in the study soil such as palygorskite play an important role on it is deposit of the interlayer. Probably the type of the salts in the soil will charge the soil pH to alkaline reaction and the precipitation will be increased. Brucite affected on exchangeable properties, and that is probably due to increasing of soil surface area in association with a decreasing in the CEC. The soil fertility probably will be effected by all these changings | ||
