Have not seen geoff's video, but i tend to refer to regenag and the works of Dr Elaine Ingham (for 9-10 density). These guys are both approved advisor under the soil food web certification, Dr Elaine has some great audio books on soils etc, Paul Taylor with his 30 years+ experince is writting a composting manual ,which will no doubt be a valuable resource.
