SOIL TURNOVER CONFIRMED. “Darwin estimated rates of topsoil deposition in the range of 0.20–0.56 cm per year, and the mean amount of soil brought upwards by the worms as 17–40 t per ha per year. More recent studies in Britain, France, Switzerland, and Germany have produced similar values for grass-dominated vegetation in a temperate climate.”
