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.
Nitrogen (N) fertilization and manure application are not traditional nutrient management practices for soybean production. Soybean is a legume plant and assumed to obtain adequate N through symbiotic N2-fixation. Also, since manure contains plant-available N in addition to other nutrients, it is preferentially used for com production to gain economic advantage from the manure-N.
