Abstract

This study documents the importance of soil fertility in the dryland farming areas of Idaho, Oregon, and Washington. Mail-based surveys conducted in 1981, 1996, and 2011 were used to document the importance placed on soil fertility by farmers. The significant findings of the 2011 survey were (1) more than 62% of the growers attributed more than 50% of their annual crop yield to soil fertility; (2) soil samples were collected at least once in a crop rotation on 91.6% of farms; (3) 31.8% of growers took their own soil samples, whereas fertilizer dealers took 62.8% of the samples; and (4) 54% of growers made their own fertilizer recommendations. Compared to the 1981 survey results, in 2011 farmers were more likely to (1) attribute more of their yields to soil fertility; (2) have their fields soil sampled; (3) collect their own soil samples; and (4) make their own fertilizer recommendations.
