When to Inoculate Soybeans?

Most university guidelines suggest inoculating if it has been more than three to five years since soybeans were last grown in the field. These bacteria have been found in soils 30 years after being planted back to perennial grasses, just at a much lower population.

Why are soybeans inoculated?

Double inoculation can provide access to nutrients bound in your soil, ultimately maximizing the performance potential of your soybeans. Establishing high populations of rhizobia bacteria can help soybean plants form nitrogen-fixing nodules at an optimal rate and time.

When can I transplant soybeans?

Plant seeds from late spring to early summer. Soybeans must have warm soil to germinate and grow. Poke holes into a cultivated bed or row to plant soybean seeds about 2 inches (5 cm) apart and one-half inch (1 cm) deep. Thin to 6 inches (15 cm) apart in all directions.
