Manure analysis
Manure is a valuable source of nutrients for crops and improves soil productivity.
Manure testing is necessary to make optimum use of manure while protecting water
resources.
Submitting samples
Obtaining a representative manure sample from each storage area is critical
to getting accurate test results. The basic guideline is to collect multiple
samples, mix them together and make a composite sample.
- Taking a representative sample
Obtain samples from at least 10 different
places and/or depths to make the composite sample. In the case of poultry litter,
sample to the bottom of the litter. If possible,
agitate the liquids before collecting the sample.
- Submitting dry samples
Submit one quart of dry manure in a Ziploc bag,
squeeze excess air from the bag and seal it. Complete the manure testing sample
information form and make sure to write your sample number or ID on the bag
and mail it to the lab. - Submitting wet samples
Submit one pint of liquid manure in a plastic container.
Do not fill the container. Make sure to leave at least one third free
space and tighten the cap securely. Complete the manure testing sample information
form and write your sample number or ID on the container with permanent ink
and mail it to the lab.
Each sample submitted to our lab should be accompanied by a sample
information form. When submitting a sample to the lab the sample information
form should be filled out accurately and completely.
Include a check for the amount due payable to MU Soil Testing, unless you have an account with us. If you have an account with us fill in the firm and outlet number and we will bill you at the end of the month.
Manure analysis sample information forms can be picked
up at the MU Soil and Plant Testing Laboratory free of charge or printed
from the Web.
