Organic agriculture Management that takes advantage of biological processes make nutrients available reduce pest pressure conserve biodiversity
Improve and maintain soil health Increase biological diversity (especially in soil food web)
Organic is not the same as “Natural” “Ecofriendly” “Green” “Sustainably Produced” “Free Range”
Fertility from Rocks Manure and compost Legumes (green manure)
Manage for animal health and efficient growth No antibiotics No hormones, steroids, or growth promoters
Animals have access to outside No CAFOs
Depend on traditional breeding No genetic engineering
Manage pest populations Encourage natural enemies Remove pests mechanically Organic sources for pesticides
Use crop rotation C-OM-M-G vs C-SB
Minimize soil erosion, improve water quality, decrease stormwater runoff Cultural practices Physical practices
What are the benefits of organic agriculture?
Equivalent overall yields on well managed organic farms Use 1/3 less fuel Less carbon dioxide produced
Nitrogen is locked up in organic matter in the soil Less likely to leach away
Soil organic matter traps carbon and keeps it out of the atmosphere
Soil organic matter holds water Decrease drought risk Decrease runoff Decrease flooding
More biodiversity in soil food web and at the surface
No pesticide residues on or in our food
More nutritious food (maybe)
So why doesn’t everybody farm organically? It’s hard Takes time Risk is great at the beginning Knowledge is almost lost Neighbors will talk about you
