An exerpt from a long report
This guidesheet estimates that for one cow consuming 30
lbs (as fed) fescue hay for a 100 day period, there would
be 23 lbs Nitrogen, 23 lbs Phosphorus, and 67 lbs of Potash
deposited back to the pasture. Some quick math
shows that if fertilizer is $250 per ton, you're getting a
fertilizer credit of about $14 per cow, or $7 per bale (1500
lb bale) just from the fertilizer value of the manure from
the cows consuming the hay. Additionally, this guidesheet
outlines the steps for you to quantify the manure
values from any given hay or supplement based on nutrient
content.
