Abstract
In volcanic-ash soil rhizospheres of ladino clover, lucerne and sometimes tomato stimulated the clover rhizobium (R. trifolii) but soyabean and Sudan-grass rhizospheres had no such effect. With the lucerne rhizobium (R. meliloti) only lucerne roots were stimulative. Soil after harvest of clover, lucerne and soyabean contained larger numbers of clover rhizobium than uncultivated soil did. A marked difference in counts of clover was found between volcanic-ash soil and alluvial clay loam.
