Manure Testing Program
Managing manure for optimum economic crop
production with minimum environmental impact requires a knowledge of the
manure's nutrient content. While standardized or "book" values listing
average nutrient contents of manures are available, they are of little value
because of the large variation that exists among different manure storage and
handling systems. Instead, manure analysis is recommended for the accurate
determination and optimum management of manure nutrients.
The
Agricultural Analytical Services Laboratory is certified
for manure testing (since 2009) by the Minnesota Department of Agriculture.
Free
sample mailers and submission forms
are available from the
laboratory or from
county offices of the Penn
State Cooperative Extension. Alternatively, you may submit your
manure sample (approximately 2 cups) in your own plastic container and a manure
submission form (pdf format).
Please submit payment with
sample.
Information
on interpreting your manure analysis report and on calculating the appropriate
manure application rates for your crops is available in the fact sheet,
Using
the Penn State Manure Analysis Report (pdf
format).

The
Standard Manure Test 1 of this program provides the minimum analysis
needed to develop a nutrient management plan. Test results in this package
include total and ammonium nitrogen, total phosphorus, total potassium and
percent solids.
Standard
Manure Test 2 contains all of the analytes in package 1 plus total
calcium, magnesium, sulfur copper, zinc, manganese, sodium, iron and
aluminum. Additional analyses are also available. |
