Secondary production of benthic stream invertebrates in agricultural watersheds with different land management practices / by R.M. Sallenave and K.E. Day. : En13-5/90-95E-PDF
"Annual secondary production of four coexisting caddisfly species (Trichoptera; Hydropsychidae: Hydropsyche spp.) was estimated in two adjacent branches of Kintore Creek, Ontario, Canada. The west branch was located in a demonstration watershed where conservation tillage was practiced i.e., mulch-finishing of row crops, planting of forage and cover crops, some no-till practices, etc. Conventional agricultural land management occurred in the watershed which drained into the east branch i.e., corn-wheat-alfalfa rotation with fall moldboard ploughing. Production estimates and densities of caddisflies were consistently higher in the watershed where conservation tillage was practiced"--Abstract.
