A field experiment over 5 years was carried out to determine whether the build up of seeds or nodule bacteria was responsible for the slow establishment of stands of clustered clover (Trifolium glomeratum), an annual legume grown on traprock soils at Amiens, S.E. Queensland. Nodulation by various strains of Rhizobium used as seed inoculants was followed by the antibiotic marker technique and immune-diffusion serology. Seedling counts were made annually and related to the pattern of rainfall in the area.
