Abstract
The satisfactory establishment of white clover in redevelopment areas already colonized by Rhizobium trifolii depends upon (a) the effectiveness of the naturalized population, (b) the ability to introduce more effective strains, and (c) the persistence of introduced strains in a competitive situation. The effectiveness of naturalized populations of R. trifolii isolated from pasture soils on the Central Plateau is inferior when compared under standard conditions with strains used for inoculation of white clover. However, the superior competitive ability of naturalized populations prevents the satisfactory introduction of inoculant strains using conventional inoculation techniques. Alternative inoculation methods have been used to increase the proportion of nodules formed from the inoculant strain. Techniques are now being sought to improve the persistence of introduced strains of R. trifolii in competitive situations.Keywords
