Resilient andisols under silvopastoral systems
Livestock can affect physical and chemical soil properties, depending on both stocking rates, and intrinsic soil properties. This study aimed to analyze changes in physicochemical properties in volcanic soils under silvopastoral systems. Two contrasting study sites were selected in Patagonia, Argent...
