I have some fresh manure currently covered with black polythene. My question is am I supposed to keep turning it over or can I just leave it? Also do you need to keep it damp?
I have always just left mine. When it is time to use, just turn it a little and use. If you want the top wet, when it rains - remove the plastic and return it afterwards.
You can also put some Garotta on or Ammonia on to help it rot down quicker
