In Magister work the spreading of macro fauna (Lumbricidae) in agrofitocenosis. Work object: research made in southwest Lithuania, Vilkaviškis region in the intensive agriculture farming in the hard granules ground. Aim of the work: to evaluate by field research southwest Lithuania hard granules soil macro fauna (Lumbricidae) spreading in agrofitocenosis depending on the kinds of growing plants, prior planting and hydrothermical regime. The methods of work: earthworm quantity was made digging 0,5 x 0,5m 2 and 0,25cm deep soil monolities and counting earthworms. By the research established that for earthworm quantity had influence growing plants, and their prior planting and hydrothermical regime. Most useful prior planting were barleys and long year grass. During research years between hydrothermical regime and earthworm number was defined strong and medium correlation relations.
