companion planting where different varieties of corn, bean and squash are planted closely together. This often entails building a mound with the soil and planting the three types of plants together as a cluster on the mound (or on several different mounds). This type of agriculture was and is used by many agriculture-oriented Indian communities throughout the U.S. in various ecosystems (arid to deciduous forest). Some communities make modifications with irrigation methods to adapt to different climate regions. The use of these three food crops has historically carried cultural and religious significance for many Indian agricultural communities. This is especially true for those who have relied upon these crops as their major source of food resources. Three-sisters farming was historically traditional agricultural practices (TAP) used by the Cherokee. However, as discussed above, it is difficult to define traditional agriculture today within the context of specific practices due to adaptations over time. For the purpose of the study, traditional agricultural practices are measured by what I perceive them to not be, in contrast to practices that have developed in the post WWII period. These conventional agricultural practices are clearly identifiable. I therefore defined conventional agricultural practices and allowed study participants to reply to all questions based on the individual's definition of TAP. Conventional agriculture grew out of the "Green Revolution." The Green Revolution started in 1960's. The technological products and advancements that arose from this revolution are used today by many farmers. They changed how most agricultural production systems function. An agricultural production system that primarily uses some or all components of the Green Revolution's technological introductions is now considered a conventional agricultural production system. Innovations associated with conventional agriculture include the mechanization or the
