Integration of water, nutrient an carbon cycling under diverse annual perennial plant community systems in agricultural landscapes

نویسنده

  • Matthew J. Helmers
چکیده

This study examined nutrient, water and carbon cycling processes and biodiversity patterns within replicated sub-watersheds that comprised different configurations of annual and perennial plant communities, ranging from conventional row crops to mixed annual and perennial systems to reconstructed native plant

Targeting perennial vegetation in agricultural landscapes for enhancing ecosystem services

Over the past century, agricultural landscapes worldwide have increasingly been managed for the primary purpose of producing food, while other diverse ecosystem services potentially available from these landscapes have often been undervalued and diminished. The incorporation of relatively small amounts of perennial vegetation in strategic locations within agricultural landscapes dominated by an...

The biogeochemistry of bioenergy landscapes: carbon, nitrogen, and water considerations.

The biogeochemical liabilities of grain-based crop production for bioenergy are no different from those of grain-based food production: excessive nitrate leakage, soil carbon and phosphorus loss, nitrous oxide production, and attenuated methane uptake. Contingent problems are well known, increasingly well documented, and recalcitrant: freshwater and coastal marine eutrophication, groundwater po...

Plant Functional Group Composition Modifies the Effects of Precipitation Change on Grassland Ecosystem Function

Temperate grassland ecosystems face a future of precipitation change, which can alter community composition and ecosystem functions through reduced soil moisture and waterlogging. There is evidence that functionally diverse plant communities contain a wider range of water use and resource capture strategies, resulting in greater resistance of ecosystem function to precipitation change. To inves...

Microbial processes regulating carbon cycling in subtropical wetlands

Wetlands host complex microbial communities including bacteria, fungi, protozoa and viruses. The size and diversity of microbial communities are related directly to the quality and quantity of the resources (i.e., nutrients, energy sources) available in the system. Microbial biomass and activity is highest in habitats where these resources are concentrated, including periphyton mats, plant detr...

Ecosystem-Service Tradeoffs Associated with Switching from Annual to Perennial Energy Crops in Riparian Zones of the US Midwest

Integration of energy crops into agricultural landscapes could promote sustainability if they are placed in ways that foster multiple ecosystem services and mitigate ecosystem disservices from existing crops. We conducted a modeling study to investigate how replacing annual energy crops with perennial energy crops along Wisconsin waterways could affect a variety of provisioning and regulating e...
