What is Acres U.S.A.®?
Acres U.S.A.® is North America's oldest publisher (est. 1971) on production-scale organic and sustainable farming. Founded by Charles Walters, for more than 50 years, our mission has been to help farmers, ranchers and market gardeners grow food profitably, sustainably, without harmful chemicals.
WE OFFER a full range of educational products — including books and pamphlets, a monthly magazine, webinars, podcasts, online courses and both large-venue and on-farm events — to help producers find timely, practical and well-tested knowledge and advice on just about any agricultural topic
Acres U.S.A. is committed to providing information about agricultural production systems that can regenerate the soil, support the farmer and rancher, and bring healthy, nutritious food to the consumer. We bring both new and time-tested voices to the discussion of “what is to be done” when it comes to building soil health, raising healthy animals and growing nutritious crops. We amplify the work of modern agricultural leaders and innovators, and we support all efforts to increase the resilience of our farms and ranches — and the people who anchor and feed our nation.
The books we sell, and the spWhat sets us aparteakers at our events, and the editors of our monthly eNewsletter and farmer-facing website represent generations of experience in building — not mining — soils. The lessons they teach are fundamental: to farm economically, one must do so ecologically.
