Sow and Plant: 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.
Harvesting: 3-4 months after planting.
Notes: Soybean cover crops are used primarily to add nitrogen to poor soil.
