Today I am talking with Dr. Ross Mars, author of The Permaculture Transition Manual. A book that covers a wide variety of practical topics including: permaculture design principles, soil building, nutrient-dense food growing, and greywater systems. In the book Ross also dispels a number of well accepted permaculture myths, such as comfrey being a dynamic accumulator.  I think we have all hear that one before, plant comfrey because its roots mine and accumulate nutrients deep within the soil.  A great concept, unfortunately one that's just not true.  As Ross found there's no scientific evidence to back that claim up. It's this scientific approach to permaculture that makes Ross's approach unique. In his book and in this interview he talks about what's worked for him and what's scientifically plausible. Today Ross and I will use that practical and realistic lens to take a look at home scale rainwater harvesting and waste treatment.   Ross will use his 20 years of industry experience to talk about the insanity of bathtub reed beds, and the need slow water down as it moves through the system. It's all about home scale greywater and blackwater with Dr. Ross Mars. Learn more at www.permaculturevoices.com/152 Support the show at www.permaculturevoices.com/support
