文摘

Earthworms with ranges in origin and foraging habits occur post long-term no-tillage. Continuous cotton supported the lowest frequencies of oligochaetes. Crop rotations of soybeans and corn provided more favorable residues for earthworms. Poultry litter is a favored food source of D. caroliniana and L. rubellus species.
