Legacy effects of contrasting organic grain cropping systems on soil health indicators, soil invertebrates, weeds, and crop yield
Elucidating relationships between the soil food web, soil processes, and agroecosystem function is a critical step toward a more sustainable agriculture. Soil and crop management practices can alter these relationships, and their effects can persist even after imposing new management practices. In 2005, the Cornell Organic Grain Cropping Systems Experiment was established in central New York. Four cropping systems that varied in fertilizer inputs, tillage practices, and weed control were compared: High Fertility, Low Fertility, Enhanced Weed Management, Reduced Tillage.

Although wetlands are known to provide vital ecosystem services, the current state of wetlands in Ethiopia in terms of their ecosystem service components remains poorly understood. Wetlands located in the UNESCO Lake Tana Biosphere Reserve have been highly degraded, but possess highly valuable resources. Therefore, this study sought to assess the major ecological states and identify the main ecosystem services (ESs), along with local people's perceptions of wetland management. Nine wetlands were selected from pristine/reference, agricultural and urban land uses of the Lake Tana area.
