Proceedings of the Integrated Crop Management Conference
Iowa State University Conferences and Symposia

The Iowa State University Integrated Crop Management Conference is Iowa's premier crop production education event. No other program in Iowa brings together the diverse range of topics, slate of expert presenters and results of the latest University research.

The ICM Conference offers workshops focusing on the latest in crop production technology. Experts from Iowa and surrounding states will provide research updates and results in soil fertility, soil and water management, crop production and pest management.

Abstract

During 2016 and 2017, June-July precipitation was below normal in many parts of Iowa creating midseason concerns about potential yield loss due to water stress. However, these concerns were not realized. In contrast, 2016 and 2017 crop yields over-performed yields obtained in many years with average of above average June-July precipitation. In Iowa, deep root systems, high soil water storage capacity, and shallow water tables are common explanations for high yields in years with below normal precipitation. How deep can roots grow? How much does groundwater contribute to the yields? To answer these questions and more, the Forecast and Assessment of Cropping sysTemS (FACTS) project was established in 2015
