Lysimeter Soil Retriever (LSR)-An Application of a New Technique for Retrieving Soils from Lysimeters

摘要

In Europe more than 2,500 lysimeters operated by research institutes and industry (Lanthaler 2005).Originally lysimeters were built for investigations of soil water and solutes,nutrient leaching and pesticide degradation (see e.g.Winton and Weber 1996).Currently lysimeters additionally used as a tool for investigations on biological processes,and structural changes of plants,including root distribution,and enzyme activities etc.(see e.g.Dizer et al.2002;Schloter et al.2005).
