Kerr Center Beginnings
• 1965-66, Agriculture Division of the larger Kerr Foundation established
• Mission: Outreach to farmers and ranchers in SE Oklahoma

So, how do you “do” sustainable agriculture?
![Page 16: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/16.jpg)

In the 1990s Kerr Center identified 8 components of sustainable ag • Healthy Soil• Water Quality & Conservation• Responsible Waste Management• Adapted Crops
![Page 18: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/18.jpg)
• Biodiversity• Ecological Pest Management• Energy Conservation• Profitability

1. Soil:
• Conserve and Create
![Page 21: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/21.jpg)
Good Soil: The foundation of a sustainable agriculture
Microorganisms in one spoonful of soil outnumber the people on earth

Erosion: still a threat Erosion threatens the productive capacity of nearly one of every three cropland acres.

One solution: Keep the soil covered
![Page 24: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/24.jpg)
Cover crops or green manures: basis of Kerr Center’s organic program
![Page 25: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/25.jpg)
Cover crops like vetch also add nitrogen, a key nutrient, to the soil.
![Page 26: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/26.jpg)
George Kuepper, Horticulture Manager,
mowing cover crop
![Page 27: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/27.jpg)
The mowed material can be tilled in, or left on the surface as mulch.
![Page 28: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/28.jpg)
We also create healthy soil with compost
![Page 29: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/29.jpg)
& compost tea...

2. Water:
• Conserve and Protect Its Quality
![Page 31: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/31.jpg)
Riparian buffers on Kerr Ranch
Buffers can trap 70-80% of
sediment and contaminants in
run off.
Protecting Water Quality
![Page 32: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/32.jpg)
Drip irrigation conserves water
![Page 33: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/33.jpg)
3. Organic Wastes:
• Manage so They Don’t Pollute
![Page 34: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/34.jpg)
Sustainable Agriculture
• Animals are raised on integrated farms • Animal wastes provide nutrients for growing
crops without polluting watersheds
![Page 35: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/35.jpg)
Kerr cows on the move: rotational grazing
![Page 36: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/36.jpg)
Electric fencing allows management intensive grazing
![Page 37: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/37.jpg)
As cows move to new pastures, manure is distributed more evenly & doesn’t pollute
![Page 38: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/38.jpg)
4. Adapted to the Environment:
• Grow Locally-Adapted Breeds and Varieties
![Page 39: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/39.jpg)
• With large amounts of inputs, farmers can raise non-adapted crops
• Farmers raise animals and plants adapted to the existing environment

• 5. Encourage Biodiversity
![Page 50: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/50.jpg)
Biodiversity
• Over 100 breeds of livestock and poultry are endangered in U.S.
• With important genetic traits: adaptability, hardiness, disease resistance• Only 20 per cent of the maize varieties reported in Mexico in 1930 are now being grown
![Page 51: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/51.jpg)

Biodiversity Threatened
• Monoculture-- planting fence row to fence row-- destroys habitat for native plants and wildlife
![Page 53: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/53.jpg)

Birds eat millions of insects and billions of weed seeds
![Page 59: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/59.jpg)
Pests:
• Manage Them with Minimal Environmental Impact
![Page 60: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/60.jpg)
Environmental Consequences of Overuse of Pesticides• Resistance: 500 insect pests, 270 weed species,
150 diseases resulting in chemical treadmill
• Non-target pests often killed, too often beneficial predators
Industrial Ag--Chemicals
![Page 61: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/61.jpg)
Health Consequences• Pesticide poisoning (worldwide)
• 10-20,000 deaths per year
• At least 3 million acute cases
• American farm workers have the highest rate of chemical-related illness of any group
Industrial Ag--Chemicals
![Page 62: Kerr Center for Sustainable Agriculture Overview](https://reader033.fdocuments.net/reader033/viewer/2022060109/555318efb4c905a7778b4785/html5/thumbnails/62.jpg)
Pesticide Use
• Rate of usage in agriculture more than doubled since 1964—3/4 of usage in U.S.
• Share of farm budget for pesticides rose 35 percent in same period
Industrial Ag--Chemicals

Consumers are the key to change
• Buying safe, nutritious, locally-produced food
• Be willing to pay a fair price for this food
