AGVISE Soil Fertility Seminars
Each year, the AGVISE Soil Fertility Seminars bring together farmers, crop consultants, agribusiness retailers, and researchers to share the latest in soil fertility, plant nutrition, and other agronomic issues that challenge our region. The seminars include a full day of invited speakers, lunch, and printed presentation guide. The United States and Canada seminars are held each January and March, respectively. This is not an event you will want to miss!
