Soil variables for use in economic analysis

Abstract

The research area lies within the lower Pajaro Valley and is that part of the Pajaro Soil Conservation District lying within the boundaries of Santa Cruz County, California (fig. 1). A large part of the 32,500 acres of Santa Cruz County cropland lies within this district. The development of agriculture in Santa Cruz County began about a century ago. Apples, still the most important single crop, were introduced in 1852 reaching their maximum expansion of about 12,000 acres in 1930.

“…Multivariate analysis is becoming a useful tool in agricultural research (Weeks and Snyder, 1957). Soil characteristics discussed herein-pore size and soil cracking-are usually not included in such analyses.…”
