摘要：A 2009 survey of cotton farmers in twelve states collected information about the use ofgeoreferenced precision soil testing (PST). Adoption of PST technology and the interval untilretesting were examined with a Poisson hurdle regression. Survey data were calibrated using apost-stratification weighting protocol. Farming experience, farm size, land ownership, variablerate fertilizer management plans, and the use of soil electrical conductivity devices were correlatedthe with period until PST adopters retested soil. Understanding how producers perceive the usefullife of soil-test information may be important for monitoring the effectiveness of best nutrientmanagement practice adoption.
