Testimonials and 'The Profitable Farm' Reviews

"We are moving to Chris Clark’s Maximum Sustainable Output. It is a win, win, win. A win for us, a win for biodiversity and a win for the farm in terms of profitability.”

'The Profitable Farm'

“Agriculture has been waiting for this book for at least a century...this model brings clarity to the process of primary food production; energy conversion is at its heart and it cannot be divorced from sound farm business management. The implications of the book are profound and of significance worldwide.”
