Work Description:

Title: Data from: Functional traits in cover crop mixtures: biological nitrogen fixation and multifunctionality
Attribute NameValues
Methodology
  • Plant functional traits and ecosystem functions were measured in fall and spring for ten different cover crop treatments (mixtures and monocultures) planted in a randomized complete block design on eight farms in southeastern Michigan. All treatments were established between August 13 and 20, 2015. Baseline characterization of soil properties at each site was conducted prior to planting. Legume nitrogen fixation was measured using stable isotope methods. Full details of the project and methods can be found in: Blesh, J. 2017. Functional traits in cover crop mixtures: biological nitrogen fixation and multifunctionality. Journal of Applied Ecology.
Description
  • This dataset contains three data files used in: Blesh, J. 2017. Functional traits in cover crop mixtures: biological nitrogen fixation and multifunctionality. Journal of Applied Ecology. There are also three corresponding metadata files. The file “Ecosystem_functions_soil_species.xls” contains data organized by farm, treatment, replicate block, and species combining the fall and spring sampling time points. These data include aboveground biomass, nitrogen and carbon content, and biological nitrogen fixation for the plant species. The dataset also includes measured soil characteristics for each farm site. The file “Ecosystem_functions_soil_treatment.xls” contains data organized by farm, treatment, and replicate block for the fall and spring sampling time points combined. These data include aboveground biomass, nitrogen and carbon content, and biological nitrogen fixation aggregated by treatment. The dataset also includes measured soil characteristics for each farm site. The file “Traits_unstandardized.xls” contains individual plant trait data, a subset of which were used to calculate an index of functional diversity after they were standardized to have zero mean and unit variance. These data are organized by farm, treatment, replicate block, and species. The corresponding metadata files: “Ecosystem_functions_soil_species_metadata.xls”, “Ecosystem_functions_soil_treatment_metadata.xls”, and “Traits_unstandardized_metadata.xls” provide a detailed description of all variables in each dataset and any abbreviations used.
