Manure Analysis
The LWTL offers analytical tests, interpretations and nutrient recommendations for animal manure and other waste by‐products. The laboratory services and the educational programs are available to all citizens of Florida and are made possible by a consortium of donors that include the USDA‐Natural Resource Conservation Service (USDA‐NRCS), Florida Department of Agriculture and Consumer Services (FDACS), the Suwannee River Water Management District (SRWMD), Sunbelt Milk Producers Association, and Florida Rural Water Association. Beginning January 2008, the LWTL operations started at Wallace Building, on UF campus in Gainesville, as a part of IFAS ANALYTICAL SERVICES LABORATORIES (ANSERV) Labs. These services are offered as a part of Nutrient Management program led by Dr. Rao Mylavarapu, in Soil & Water Science Department.
What is in a manure test?
Laboratory analysis will include a test for nitrogen (N), ammonium (NH4‐N), phosphorus
(P) and potassium (K) as well as percent moisture, percent solids, percent ash, and pH. Based on test results,
nutrient recommendations for N, P, and K are provided for selected crops and up to three different crops per sample
can be selected from a given list.
How to get Started!
Samples can be delivered to the LWTL via packaged
mail or dropped off in person on any working day. All samples
should be appropriately labeled along with completely filled out forms
and any applicable fee. Appropriate
forms can be
downloaded and printed
from the link above.
All the requested information
on the forms must be
provided including the crop
codes, county of sample origin,
current method of application
and previous application
history, if any. For
poultry litter samples, at
least one half‐quart ziploc
bag volume of sample
should be provided. For all
liquid, effluent and slurry
samples, only leak‐proof
bags or bottles should be
used to avoid spills. Samples
must be appropriately labeled
with grower’s name
and sample ID. Samples
should be delivered to the
address provided on the form.
