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

Cover crops can provide many benefits to row crop agriculture, such as reducing water loss and soil erosion, increasing soil organic matter and nutrients, and suppressing weeds. The incorporation of cover crops is also generally perceived as an important forage and refuge for natural enemies of insects and weeds. Diverse agroecosystems that include cover crops can have decreased pest pressure compared to monocultures (Root 1973). For example, soybean aphid populations can be lower in soybean fields with a rye cover crop (Koch et al. 2012).
