The coupling between nutrient and patch dynamics is disrupted by the pastoralist settlements. Livestock grazing generates a centripetal transport of soil water, solutes and nutrients, towards the corrals. The nutrient balance was negative in livestock stations, indicating depletion of soil nutrient stocks. Changes in accumulation and spatial distribution of soil resources can indicate degradation of drylands. Effects of pastoralist settlements on arid woodlands should be understood for soil resources management.
