UI Extension, Elmore County provides expert recommendations on agricultural topics such as crop production, enterprise budgets, variety selection, pest control, plant diseases, fertilization and irrigation management.
We also teach applied scientific methods to help restore soil with organic matter and improve production while conserving resources.
Large and small farms can be given crop consulting and on-farm field surveys using current technical information from the University of Idaho.
