Current Project: Nutrient Management Curriculum

Nutrients on dairy farms have three basic fates: 1) they are exported from the farm in products sold; 2) they remain on the farm to be recycled; or 3) they are lost to the environment. To help farmers and farm advisors as well as students in agriculure related majors better understand management of nitrogen for corn, lime management for field crops, the value of manure, and the concepts and applications of whole farm mass balances assessments, learning modules were developed. This page gives you access to learning modules for in-class or extension teaching. This is a project in progress and updates will be added over time.

Each learning module consists of an outline, teaching guides including a background lecture and a workbook with three components: (1) software demonstration (1 hr); (2) instructional examples (1 hr), and (3) advanced exercises (1 hr), designed as a 1-hr lecture and 3-hr laboratory session. Class materials include (1) software, (2) data collection sheet, (3) user manual, (4) tutorial workbook, and (5) a glossary of terms.

This project is funded by the Center for Dairy Excellence (small farms project) and NESARE (a professional development grant)
