Calculating liquid storage capacity
Use the following worksheet to calculate the current
storage capacity of your liquid manure storage facility.
Compare the volume of liquid
manure produced to your current manure storage capacity.
Is the capacity of your manure storage area adequate?
If not, you may need to consider additional or alternative
storage practices.
