Organic agriculture


Management that takes advantage of
biological processes


make nutrients available


reduce pest pressure

conserve biodiversity


Organic agriculture mimics
the natural ecosystem

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

What are the benefits

o
f organic agriculture?




Equivalent overall yields on well
managed organic farms


Use 1/3 less fuel

Less carbon dioxide produced

No pesticides to run off or drift

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
