Prepare the soybean planting area by pulling any weeds and raking out all debris. Dig into the top 10 inches of the soil and smash any large clods of dirt.
Add 4 inches of compost to the soil and mix it into the top 10 inches using a gardening fork. Rake the bed until it is level and smooth.
Push the soybean seeds down 1 inch into the soil, spacing them 2 inches apart. If planting more than one row, space the rows 20 inches apart.
Water with a garden hose until the soil is wet to a depth of 8 inches. Keep an eye on the moisture content of the soil because it can dry out quickly in July.
