At No Till Nation, we farm under the philosophy that a plant's immune system is heavily derived from it's soil surroundings. This is why we practice "Tarps over Tilling". Tarps are laid over a section of land we want to farm. The sun's heat, coupled with a lack of light causes plants, like weeds, to die. The soil beneath the tarps hasn't been distrubed leaving beneficial worms, fungus and insects ready to break down the dead plant material; putting nutrients BACK into the soil.
"Pay The Farmer or Pay The Doctor!"
