Pasture renovation by legumes sod-seeding, which consist in drilling legumes seeds in a grass dominated sward, is a way of increasing both pasture productivity and quality. In North America the use of this method is increasing in popularity. However, results are variable and some problems still persistent. Factors determining the outcome of legumes sod-seeding during pasture renovation are reviewed. Particular attention is given to the role and effects of herbicides, which are generally used to suppress the competition provided by the resident grass vegetation. The use of physical sod suppression methods (eg: mowing or grazing) as an alternative to herbicides is also discussed
