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.
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. |

In
many manure storage systems there is considerable variation in the manure
nutrient content even within the storage unit. It is recommended that at least
once after a manure storage is constructed a detailed analysis of the manure be
performed to determine the amount of this variation. This process involves
sampling the manure periodically as the storage is emptied for field
application. The samples may be taken after a specific number of loads or
whenever a significant change in the manure consistency occurs. To facilitate
this sampling, a special kit has been developed that contains sample bottles and
information sheets for 5 samples that can be submitted together for this
purpose. After the five samples are submitted, a separate summary report
detailing the minimum, maximum, average, and variability of the analytes tested
in the five samples will be provided in addition to the individual analytical
reports for the five samples. Free sample mailers and submission forms are
available from the laboratory or from county offices of the Penn
State Cooperative Extension. Please submit payment with sample.
