It’s possible to cultivate Paulownia with other crops (intercropping), especially during the first 2-3 years. Wheat, corn, soybeans, peas, beans, barley, cotton, vegetables and herbs can be farmed between the rows of Paulownia. A farmer can receive double income – both from the crops grown between the trees, and from the trees themselves. The trees provide good microclimate for growing co-cultures and increase their productivity. Leaves and flowers of Paulownia are rich in nutrients and it appears to be a both cheap and useful source of nitrogen, which enriches the chemical composition and structure of the soil.
