Snap-shot assessment of nutrient use efficiency
Snap-shot Assessment wheel; crop, feed, cow, milk, manure, fertilizer

How can nutrient use efficiency be determined and monitored easily on dairy farms? Over the past several years researchers at the U.S. Dairy Forage Research Center and the University of Wisconsin-Madison have been developing and using rapid assessment methods to provide snap-shot assessments of feed, fertilizer, and manure use on dairy farms in various settings. The most recent work was a survey of 54 Wisconsin dairy farms known as On Farmers' Ground.

Here we provide many of the tools used in the On Farmers' Ground project in the hopes that others will find them useful in determining and monitoring nutrient use efficiency on dairy farms.


Materials available (PDF format) on this site include: 

A FACT SHEET giving an overall explanation of nutrient use efficiency, the importance of knowing it, and how to measure it.

A sample NUTRIENT MANAGEMENT SURVEY - the questionnaire that was used in the On Farmers' Ground project.

A sample MANURE SPREADING BOOK - a document to help dairy producers keep track of when, where, and why they spread manure.

An example of an On Farmers' Ground FINAL FARMER REPORT for an individual farm in the study.
