Cereal Rye Cover Crop Termination Timing and its Impact on Weed Suppression and Soybean Yield | Wisconsin Weed Science

With increased temperatures and recent rain, Wisconsin fields that were planted with a cereal rye cover crop in the fall are showing signs of life. If you are planning to manage your cereal rye cover crop as part of an integrated weed management program for in season suppression of small seeded annual weeds, it is important to ensure a large amount of biomass is produced by the time of termination.

Nitrogen deposition accelerates soil carbon sequestration in tropical forests

Forest soil carbon (C) storage plays a central role in sequestrating atmospheric CO2 on timescales from centuries to millennia. However, our current understanding of soil C sequestration in response to N deposition mainly focuses on mid-to-high latitudes in the Northern Hemisphere, where N supply typically constrains forest growth. We lack data about changes in soil C stocks in tropical forests, where most ecosystems are N-rich or N-saturated. Using more than a decade of continuous N addition experiment and a meta-analysis, we found that excess N deposition can significantly increase soil C in N-rich tropical forests. However, enhanced C sequestration in tropical soils is not a good reason to justify excess N emissions to the atmosphere. Data have been deposited with the South China Botanical Garden of the Chinese Academy of Sciences () All other study data are included in the article and/or [ SI Appendix ][1].
