Soil sampling
Soil Sampling without GPS, 2002 – 2005

  • 30% of Sao Paulo sugar mills grid soil sample

    • 70% of the total area, Silva et al (2010)

  • In US, reduction in grid and zone soil sampling

    • Localized precision soil sampling methods common if associated with a reputable third-party expertise

    • More than half of U.S. service providers offered soil sampling with GPS, 59% offered grid soil sampling, one-fourth offered soil sampling by soil type

      • (Whipker and Akridge, 2009)
