  12. Soil Sampling • 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)
