Pasture renovation techniques were evaluated in Digitaria decumbens and Lotononis bainesii mixture, at Mt. Cotton, southeast Queensland, where lotononis remained in trace proportions. Cultivation involving chisel ploughing or disc harrowing was ineffective in a renovation technique study, presumably due to deep seed burial, but a mow-and-remove treatment and a burning enhanced seedling recruitment of lotononis were effective. Vegetative regrowth of nodal buds was enhanced by a mow-leave, the burning and the mow-remove treatments. A herbicide (Glyphosphate) treatment did not contribute to suppression of associated grass and it appeared to have killed all lotononis and volunteer species but not Digitaria decumbens, A short-duration heavy grazing experiment indicated that in December or January heavy grazing was more successful than in March, May, or September, whereas nil grazing increased soil seed reserves significantly. It is concluded that the success of pasture renovation by the creation of a “gap” and subsequent seedling recruitment requires a favourable combination of soil seed reserve increment and favourable conditions for seeding recruitment.
