Abstract
A method is described which uses a composition including a small non-toxic amount (less then about 0.001 part per part of the composition) of a water soluble adhesive agent, particularly an alkali metal salt of carboxymethyl cellulose, with water and with nitrogen fixing bacteria for applying the bacteria on the surfaces of seeds of the plant family leguminosae or on particles surrounding the seeds including soil particles or combinations thereof. The nitrogen fixing bacteria are of a symbiotic species and are selectively isolated from effectively nodulated plants of the variety to be inoculated so that they are efficient in inducing effective root nodulation in the plants. Novel compositions are described which include the bacteria mixed with water and the adhesive agent and which are prepared by a manufacturer, frozen for shipment, and then thawed and substantially diluted with water by the farmer or other user for application.
