Lumbricus terrestris earthworms exposed to 11 soils of contrasting properties produced, on average, 0.8 +/- 0.1 mg(CaCO3) earthworm(-1) day(-1) in the form of granules up to 2 mm in diameter. Production rate increased with soil pH (r(2) = 0.68, p < 0.01). Earthworms could be a significant source of calcite in soils. (C) 2011 Elsevier Ltd. All rights reserved.
