The sustainability of agricultural and livestock systems has been a major challenge for researchers throughout the world. Concerns regarding the impacts of current agronomic and management practices have been raised in many quarters in recent decades. It is evident that limited knowledge of plant-animal-soil interactions has historically generated a number of negative environmental impacts. In grazing systems, those negative impacts can be observed in both intensive and extensive systems, and in both natural and sown pastures.
