When we put together our company, SFI suggested
that to start, thee proper proportions of material to use are:
5 Gallons
5 lbs (20 cups)
50 Gallons
7 lbs (28 cups)
500 Gallons
15 lbs (60
cups)
This is very biologically active stuff, but still
the numbers and the line on the graph should be pretty much the same with any
good compost. I am not sure that it is a straight line either!
