A prototype of an automated soil sampling system for measuring soil pH on-the-go has been created and evaluated (Papers No. 98-3094 & 99-1100). It allows measuring soil pH every 10 seconds while traveling across the field (automated soil pH mapping). Geostatistical, agronomic and economic methods were used to generate a model for quantitative assessment of net return over cost of liming for different lime management techniques (including automated and grid soil sampling, fixed and variable rate liming). This model allows one to conduct comparison analysis while changing various field parameters, costs, prices and other related constants.
