This technology fertilizes soil through inoculating earthworms and organic materials under natural mechanism. It could enlarge extension area up to 10%-15%, reduce fertilizer utilization about 50%, which, to some extent, could avoid damage brought by excessive use of fertilizers and pesticides, and maintain biological diversity and soil fertility. It can be widely used in tea, coffee, rubber and other cash crops and forestry production.
