Quarterly Journal

"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.”

ANDREW HATTAN PhD Dairy Farmer and Cheesemaker - Stonebeck Cheese

“We found it very helpful working with Chris. He put a lot of work in to find the areas we could improve on, to help us become more profitable. By reducing cow numbers, purchased feeds, vets bills and fertiliser, we are heading towards Maximum Sustainable Output.”

'The Profitable Farm'

"The authors brilliantly pour detailed farm business data, natural assets and landscapes, plus energy and nutrient cycles all into a black box. The emerging calculations – combined with their expertise to deliver a profitable and sustainable approach and based on Maximum Sustainable Output or MSO – are a bit genius.

Recommended for all farmers, policymakers and nature advocates"
