We will use an inoculant containing nitrogen-fixing bacteria. The product has a brand name of NITROGIN and is described as
follows:
Nitragin inoculants are cultures of nitrogen-fixing nodule bacteria
(Rhizobium spp.) in a peat-base medium prepared for application to legume
seeds before planting. Rhizobia working in nodules gather air nitrogen and
make it available to their host.
