    Add aged compost to the soil before planting, and side-dress your plants at least once during the growing season. Because soybeans are nitrogen fixers, they don't need a lot of additional nitrogen.

    There are thousands of soybean cultivars in the world, but in many parts of the world, field varieties are grown for industrial uses (such as livestock feed and oil production), while vegetable varieties are grown for direct human consumption. Green soybeans are among the most popular for eating cooked, but black soybeans are a favorite for drying. If you want to make milk or flour, opt for yellow soybeans. A few popular soybean varieties are Early Hakucho and Envy.
  • Question
    Do you need to stake soy plants?
    Community Answer
    Soy is not a vine or a climbing plant, so you generally don't have to worry about staking it. However, if the plants become too heavy with pods, you can support them with thin stakes. But this is something you may only have to worry about if the growing conditions are exceptional and the plants are extremely healthy.
