Earthworm Biotechnology and Global Biogeochemistry

摘要: Publisher Summary This chapter discusses a heuristic consideration of organic “wastes,” soil science, and the environmental role earthworms. view is based on four points: (1) upper 23 cm Hoosfield plot, despite an input carbon greater than usual in agriculture, not yet saturated with carbon, (2) Some earthworms can burrow to depths exceeding 100 land heading poleward from tropic latitudes 1500 tropics. Plant nutrients are added accordingly, either as eliminations gut body wall or by translocation opposed runoff surface through earthworm burrows, (3) Even 35 x l06 g manure ha-1 year-1, used less needed achieve soil-carrying capacity for 10% what may be manageable amount. Earthworms indeed principal tillers agents humification worldwide, (4) Efficient temperate soils brought together region accelerate turnover humification.
