What are Biological Soil Amendments of Animal Origin (BSAAO)?


A soil amendment refers to any material added to the soil to improve the physical or chemical properties.  Biological soil amendments are those that include ingredients of plant, animal, or human origin.


Composting is a process to reduce harmful bacteria in manure and other biological feedstocks.  The process must be monitored to ensure that specific time and temperature intervals are met to ensure safety.  Composting requires oxygen, so turning or aeration is required.  A static pile of manure is not composted.
