Abstract
Suitable site conditions are essential for productive growth of black walnut (
Juglans nigra L.). Field officers at the Natural Resources Conservation Service (NRCS) in the Midwest are often asked, "What is a good walnut soil?" Current NRCS information available to most field offices rates soils only as "suitable" or "unsuitable" for black walnut. To refine the precision of this categorization and more effectively answer this question, we developed a quantified suitability model that uses 10 soil and site factors from the National Soil Information System database (NASIS). Our interpretive model generates a black walnut suitability index rating for each soil component within each soil survey map unit.
