Abstract
The spreading of Rhizobium meliloti strains in various autoclaved soils was measured by using simple modifications of established techniques. Behavioral mutants were used to demonstrate that efficient spreading requires active motility and chemotaxis. The rate of spreading was affected by physical or chemical differences among soils and by changes in water content.
