بررسی ویژگی‌های کانی شناسی زمین‌های زیر کشت نیشکر در مقایسه با کشت تناوبی و زمین‌های بکر جنوب خوزستان

The change in composition of clay minerals is possible in uncultivated lands that sugarcane is cultivated for many years. For this study, mineralogical properties of soil samples from described profiles in four farms with more than 15 years cultivation were determined and  compared with nearby uncultivated lands and farms under rotation cultivation. The results showed that expandable minerals were abundant in the Ap horizon of the cultivated soils, unlike in the uncultivated soils, while only small amounts were found in C horizons of cultivated soils. Also, the surface horizons of the uncultivated soils contain more palygorskite than the surface of  cultivated soil, but this subject is not seen in depth of profils. These changes are more observable in soils under sugarcane cultivation  in comparison with  soils under rotation cultivation because of the differences in irrigation, biomass production and food requirments and therefore intensive cropping and strong irrigation over a long time could result to the changes in soil minerals and other factors such as soil nutrient requirements.
