Manure Analysis Update: 1998-2010

John Peters Department of Soil Science University of Wisconsin – Madison

Introduction

 Knowing the nutrient content of manure is

critical for nutrient management planning.

 New species and management categories have

been established.

 Follow trends and update book values

Acknowledgment

 Data for this summary was provided by the

following laboratories. – AgSource Laboratory – Dairyland Laboratory – Rock River Laboratory – UW Soil and Forage Laboratory

Laboratory Data

 27,391 lab values from 1998-2010 were

summarized by management (liquid vs. solid) and species

 Includes 14,676 liquid dairy, 6,371 solid dairy,

2,298 solid poultry, 1,568 liquid swine, 553 solid beef, and 155 solid swine samples, as well as smaller numbers of samples for other species

1167 798 1763 641 1187 5477 1053 3160 1042

Numbers listed represent 59% of total samples where county was listed.

“Book Values”

 Nutrient concentrations can be estimated

using “book” values for available N, P2O5, and K2O

 Testing is needed to determine if a farm is

typical and to establish an individual farm “typical” value

 If management and feeding practices do not

change, manure analysis values will not vary significantly on a farm

Manure Sampling and Testing

 Manure testing takes management practices

into account and delivers more accurate values to use for farm specific nutrient management planning

 Lab analysis summaries can be used to

monitor long term trends in manure nutrient content as it is affected by management changes over time

* If manure has been applied to the same field at similar rates for 2 consecutive years, increase the nutrient values an additional 10%. If manure has been applied to the same field at similar rates for three

• r more consecutive years, increase the nutrient values by 15%.
