This project is designed to re-evaluate soybean response to lime in Iowa and to collect data needed to support any needed change in existing recommendations. The project uses precision agriculture technologies, replicated strip trials, and dense soil sampling to identify optimum soil pH for corn and soybean, studies the variation in crop response to lime across soil series and topography, and compares laboratory analysis methods to assess lime needs and lime ECCE.
