Ask
Extension…
What’s my manure worth?
By
Nancy Glazier
Hopefully everyone
is giving this month’s Ask Extension question serious thought. As
fertilizer prices continue to shoot higher and higher due to global demand
and the link to the petroleum price, your manure is worth more than ever.
To learn how much
value is in manure on your farm, consider these factors:
• Soil test. This is more critical than ever. Spread your manure
on fields that need fertilizing the most and apply to nutrient needs.
• Manure test. When’s the last time you had manure analysis
done? Concentrated Animal Feeding Operation (CAFO)-regulated farms need
to test manure for their plans, but all livestock farms should have manure
analyzed at least twice a year. Dairy One in Ithaca will test manure for
$35. It can supply a kit, or you can call your Extension office. To find
a sample drop-off site in the region, call Dairy One at 800-496-3344.
• Nitrogen conservation. Incorporation is the key to capturing ammonia
in manure. And think about your neighbors – they will look at you
more favorably when you incorporate or inject.
Check out the Manure Credit Calculator at the Cornell Nutrient Management
Spear Program website. It’s a very cool tool that lets you plug
in manure analysis and current and past application rates. You earn more
nitrogen (N) credit with timely tillage.
See Calculator example
Fertilizer costs can
be added in the calculator on a per pound basis. The example calculator
sheet shown here is for Aug. 6 when rates for N, phosphorus (P) and potassium
(K) were 45, 58 and 36 cents per pound, respectively. Using a recent manure
analysis, the fertilizer value was $45 per acre.

If you don’t have Internet access, let me know and I can help you
out.
