Reducing the amount of pesticides and fertilizer dramatically lowers overhead. At the same time, farmers are less susceptible to the health risks associated with applying pesticides, and the farms themselves trend progressively towards being completely organic. In fact, organic status-the best hope for a sustainable ecosystem-is usually attainable after about five years.
如此一來，不僅農藥與肥料減量，降低生產成本，同時也降低施藥風險，保障農民健康，農地也能漸進式地有機化，大約 5 年就能變成真正的有機農地，維護生態永續經營。
