Home About Us Information Benefits Recipes Order "That wassome of the best beef I've ever eaten" -Theresa, Norman, OK Free-range Grass-fed/Grass-finished Beef At Ranney Ranch, in the beautiful high mesa country of central New Mexico, we raise Angus calves on nothing more than native grasses and mother’s milk, producing healthy and great tasting beef while using only the most humane handling techniques and sustainable land use management and grazing practices. We have been at the forefront since 2004 producing and marketing entirely grass-fed/grass-finished beef and are proud to offer our superior beef directly to customers nationwide. We sell online half and whole beeves and will arrange for you processing, dry-ageing, packaging (into 1-2 lb. portions), and shipping. We are "Certified Grassfed" by the American Grassfed Association (AGA). Our eco-friendly practices were profiled recently in TIME magazine (9/7/2010). Also see a story about our grassfed beef in the New York Times Magazine (10/10/2010) by food writer, Kim Severson. Nancy Ranney will speak at the Quivira Conference in November on "The Carbon Ranch".

ASU/Shell Preliminary Results2016 • Potential: build SOC in grassland soils by short-term/rotational grazing AMP • Accrues 9 TCO2 equiv/ha-yr more than continuous grazing practices • More methane taken up than emitted • 30% increased infiltration rates • Grasslands 40% of global land mass, significant potential for net GHG sink
