Soil is an important factor for the growth of any plant. Your plants get all the major nutrients from the soil. Peat-based potting soil is the best option for growing corn plants. 

You can also add compost, fish emulsion, chicken manure, and all-purpose fertilizer to make potting soil richer.  This soil has all the basic nutrients which your corn plant needs at the start of the growth.
