The formula to calculate the Manure Application Rate (MAR) is:
\[ MAR = \frac{M}{A} \]
Where:
Let's say the amount of manure used (M) is 5000 lbs and the number of acres (A) is 10. Using the formula:
\[ MAR = \frac{5000}{10} \]
We get:
\[ MAR = 500 \text{ lbs/acre} \]
So, the manure application rate is 500 lbs per acre.
