Tenets of Organic Agriculture

Some Basic Tenets of Organic Agriculture:

-Crop rotation - to control nutrient levels and imbalances in the soil
-Enhancing habitat for natural enemies - So no single population of pest can become prevalent
-Barriers - So invasive species can't spread
-Cover cropping - To control weeds during the off season and let the soil regenerate
-Minimum tillage techniques - To preserve soil aggregation which protects against erosion and gleying
-Mulching - To retain soil moisture and water
-Drip irrigation - To lose less water as runoff
-On-site fertility - To add no more than is taken from the soil system
-Composting - To conserve and recycle soil nutrients
-Approved insecticides and herbicides - Only as a last-ditch effort at control
Minimum Tillage
