Feeding

Seedlings
Not typically required for legumes due to nitrogen fixation. If soil is exceptionally poor, a low-nitrogen starter may be applied.
Growing
Minimal, only if soil tests indicate specific phosphorus or potassium deficiencies. Avoid nitrogen.
Flowering and fruiting
Phosphorus and potassium can support pod development. Soil testing is recommended for precise needs.
How often
Rarely: soybeans fix their own nitrogen.
Note
Edamame, as a legume, effectively fixes atmospheric nitrogen, obviating the need for supplemental nitrogen fertilization.
