A return to natural farming Since ancient times, plants have taken their nourishment from the soil and been eaten in turn by animals; the animals returned these nutrients to the soil through their excrement and carcasses. This unending cycle made up the complex and rich cycle of ecology.
回歸自然的耕作亙古以來，植物從土壤吸收養分成長，供動物食用；動物糞便和殘骸又回歸土壤，成為肥分，如此循環不已，構成豐富又複雜的生態體系。
