The Robert Bosch Foundation, a non-profit organization for public interests and welfare, has sponsored a series of scientific workshops dealing with modern agriculture and its impacts on soil functions and soil fertility. Most of the participants are experts in their fields and members of the German Soil Science Society. The group after a critical analysis of the present situation made conclusions and recommendations, which have been summarized in seven publications and a special memorandum. This article describes the main topics of these documents and summarizes the recommendations. 相似文献
