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

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

“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

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