Description
A survey of clover-ley pastures in South-east Australia had shown extremely low populations of Rhizobium trifolii following crop production. A long-established subterranean clover pasture growing on a strongly acid soil was disrupted for two seasons of wheat production and populations of R. trifolii were measured in the presence and absence of soil liming with cultivation and direct drill methods of crop establishment. The populations of R. trifolii were substantially reduced in the absence of lime with both methods of crop establishment, confirrning the need for seed inoculation of subterranean clover when the clover-ley is being re-established. A higher surface pH from soil liming with the direct drill method, and increased R. trifolii populations resulted.
