    • Integrating Variable Rate Technologies for Soil-applied Herbicides in Arizona Vegetable Production

      Nolte, Kurt; Siemens, Mark C.; Andrade-Sanchez, Pedro; Plant Sciences, School of (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2011-02)
      Precision herbicide application is an effective tool for placing soil incorporated herbicides which have a tendency for soil adherence. And while field implementation depends on previous knowledge of soil textural variability (soil test and texture evaluations), site-specific technologies show promise for Arizona vegetable producers in non-uniform soils. Regardless of the method used for textural characterization, growers should keep in mind that textural differences do not change in the short/medium term, so the costs associated with defining texture-based management zones can be spread over many years.
    • 2001-2002 Arizona Vegetable Crop Budgets: Southern Arizona (Cochise, Pima and Pinal Counties)

      Teegerstrom, Trent; Call, Robert; Gibson, Rick; Agricultural & Resource Economics (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2001)
      This 2001-2002 Arizona Vegetable Crop Budget Book is comprised of tables estimating the operating and ownership costs of producing vegetable crops in Central Arizona. The costs are computed for a representative farm using representative cropping operations and are not a statistical sample of farms in the area.
