Effective rhizobial and mycorrhizal symbionts provide a low-input method to improve tree nutrition and soil fertility, without the use of fertilizers. Successful inoculation of trees with symbionts requires effective and competitive strains, which promote growth and which persist in the field. Until recently it has not been possible to evaluate field persistence. This proposal capitalises on new developments in molecular biology in a combined programme in which rhizobial and mycorrhizal inoculants for the important fodder tree Calliandra calothyrsus will be evaluated for their effectiveness in promoting tree growth, for their persistence and capacity to influence tree growth in the long term and for their ability to be shared with intercrops. Appropriate uptake pathways will be developed.
