ABSTRACT:
A process and apparatus used in inoculating leguminous plants with nitrogen fixing bacteria is disclosed. The process involves the preparation of an aqueous dispersion of the bacteria from a suitable source material and its dispensation to the soil in the fluid state and through the use of a separate dispenser from that handling the seeds. The apparatus includes a soil opening implement that forms a furrow during use and separate means for delivering the aqueous dispersion and seed to the furrow. A positive displacement pump provides quantitative dispensation of the bacteria.
