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’ Groundproject 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 SHEETgiving an overall explanation of nutrient use efficiency, the importance of knowing it, and how to measure it.

NUTRIENT MANAGEMENT SURVEY– the questionnaire that was used in the
On Farmers’ Groundproject.*
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 REPORTfor an individual farm in the study.*
Four scientific journal articles related to the
On Farmer’s Ground project:
