Abstract
A 2009 survey of cotton farmers in twelve states collected information about the use of
georeferenced precision soil testing (PST). Adoption of PST technology and the interval until
retesting were examined with a Poisson hurdle regression. Survey data were calibrated using a
post-stratification weighting protocol. Farming experience, farm size, land ownership, variable
rate fertilizer management plans, and the use of soil electrical conductivity devices were correlated
the with period until PST adopters retested soil. Understanding how producers perceive the useful
life of soil-test information may be important for monitoring the effectiveness of best nutrient
management practice adoption.
