How much manure do farmers use?

The amount of manure farmers use varies widely depending on the type of farming, crop needs, and local regulations. On average, a dairy farm might produce about 100,000 pounds of manure per cow annually, while crop farmers may apply between 5 to 20 tons of manure per acre per year to enhance soil fertility. Farmers often conduct soil tests to determine the appropriate amount needed to optimize crop yields without causing environmental harm.
