Abstract
  • Farmers and nonfarmers, 500 in each group, were interviewed face­to-face concerning knowledge, attitudes, beliefs, and assessments of soil erosion on their farm or in the immediate area of their farm. The sample was divided equally between the Willamette Valley and the Colum­bia Basin, representing two distinctly different climatic and socio­graphic regions. Questions were about the importance of soil erosion, knowledge of topic, attitudes, and sources of information. Farmers were asked additional questions about adoption of specific soil erosion control practices, year of adoption, and problems, if any, experienced with each. Both groups were asked questions about seriousness of soil erosion and steps that should be taken to reduce it. Results were shown and discussed in two Special Reports of the Oregon Agricultural Experi­ment Station (Special Reports No. 764 and 765). This report is concerned with aspects of minimum tillage. The number of farmers using minimum tillage was nearly zero in 1940. Adop­tion started in the early 1950s in the Willamette Valley and about 10 years later in the Columbia basin. Rate of adoption was about 0.7 per­cent of the farmers per year in the Willamette Valley and 0.3 percent per year in the Columbia Basin. These rates remained constant until the early 1980s when a more rapid rate of adoption set in. At that time, minimum tillage was increasingly recognized as the management practice that maximized net returns during a period of rapidly declining prices for farm products. Evidence is given that supports the hypothesis that minimum tillage is being used as an economically attractive management alternative rather than as a conservation practice.
