The principle of matching the biological requirements of a crop to the characteristics of the land was used as a basis for developing a land suitability classification for potato ( Solanum tuberosum L.). Land characteristics needed to assess land suitability for potato production were obtained from soil surveys based on Soil Taxonomy. Soil Taxonomy provides readily available information to characterize a few important land qualities for potato production. To predict responses to soil and crop management, land suitability assessments for three levels of input, zero, low, and high, were developed for potato. Because Soil Taxonomy is used as a basis to assess land suitability, the proposed classification system is independent of national boundaries, and can be used to obtain estimates of capabilites of land wherever a soil survey based on Soil Taxonomy is available.
