Perspective:Towards improved grazing management recommendations for sourveld

Abstract

Critical evaluation of grazing management recommendations for sourveld revealed scientific, economic and practical deficiencies. These recommendations are seldom adopted. Recent scientific evidence has facilitated the adoption of certain principles in new practical, economically viable recommendations aimed at maintaining or improving the resource while facilitating good animal performance. These are based on the principles that defoliation, particularly by sheep, is detrimental to the vigour of the preferred species and that extended rests are necessary as compensation. Recommendations are aimed at optimal utilisation of veld burnt in spring after a full growing season rest. This is followed by compensatory rests every alternate year with sheep alone or use by cattle for one or two years, depending on sheep:cattle ratios, followed by a full season rest. Rested veld utilised during the dormant season is an important feed source.
