Desertification causes many problems as arable land is being taken over by deserts. Use of remote sensing to evaluate the effects of environmental factors on soil salinity in a semi-arid area. Apart from their toxic impact as such, these positively charged ions impede the acquisition of other positively charged ions vital for crop growth (particularly potassium and calcium). Soil salinization is a serious problem itself, but it rarely comes alone.
