Sustainable farming practices
The following reduce soil erosion:
Terracing hill sides:
Low or No Till Plowing (wind and water)
Crop Rotation (keeps nutrients)
Rotating heavy feeders, moderate
feeders with soil builders
Plant during fallow(off) season.
Keep nitrates from leaching out of topsoil
Also keep soil orgs healthy and “fed”
Prevents excess N from runoff into water

Factory Farming: Increasing
Antibiotics are commonly used in animal
Animals are bred to grow faster and to be
more desirable for market.
E.g chickens with more breast meat.
Synthetic hormones are approved for use

Waste treatment regulations are more lax
than for waste from people.
