THE NITROGEN AND HUMUS PROBLEM IN DRY-FARMING

The impact of Rangelands conversion to dry-farming on the loss of organic carbon and nitrogen of soil in the vicinity of Sanandaj

To determine the effect of conversion of rangelands to dry land farming on losses of carbon and nitrogen, Dryland farming areas and adjacent rangelands were determined. Popular areas in each of the treatments were determined and soil sampling was done. Treatments were chosen so that each treatment and the surrounding area (control), topography and climate characteristics are the same and the on...
