This publication contains information on establishing a black walnut plantation.
Ideal sites are stream bottoms, flood plains, or odd corners.
Such areas may be placed in walnut production with little or no loss of agricultural production. Historically, walnut has increased in value faster than the inflation rate. Using present market figures probably greatly underestimates the future market value. Figure 1 shows where walnut can be grown as a commercial crop. Some isolated areas further west will support adequate walnut growth.
