Nancy Ranney of the Ranney Ranch in Corona, New Mexico describes practices she and her family are using to keep their land and livestock healthy and sustainable.
49. Benefits of Rotational Grazing
Management
• Lower costs (feed, labor, fuel, few bulls)
• Increased animal productivity
• Higher stock density
• Increased biodiversity & resilience
• Opportunity for grassfed beef program

"That was some 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".
51. 90% of Soil

plants
So how we
manage plants
is critical
Soil is to the plant what the rumen is to the cow
64. One-seeded Juniper
• Av. tree consumes 40-80 gal/day,
or upwards of 8-12,000 gal/yr
• Tests show SOC levels plummet in
soil horizons below litter layer
• Water holding capacity of soil
greatly reduced
82. Documented: 1% increase SOC can
hold addt’l 60,000 gal water/ac
• On 10,000 ac, hold addt'l 600 M gal
• If even 80% evapotranspires, 120 M gal
enters shallow & deep GW
• If 30% re-emerges from soil, approx
110 ac ft now available to ranch
soils(36 M)
• 70% into deep GW (84 M gal water)

84. ASU/Shell Preliminary Results 2016
• 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
