Data set contains results of chemical analysis of wetfall samples collected on Konza Prairie. Analysis is done by the Central Analytical Lab (CAL), Champaign, IL as part of the National Atmospheric Deposition Program (NADP). NADP data products available on the NADP/NTN web site (nadp.slh.wisc.edu/data/NTN/) include: Annual Data Summaries, Semiannual Data Reports, Annual and Seasonal Averages, Monthly Averages, and Weekly data. Konza Prairie LTER archives and provides the weekly data in electronic form before May 2019.

Two permanent plant composition plots were marked with conduit in each of the 64 plots. Canopy cover was recorded in a 5 m2circular area surrounding each of the plots.  At approximately 5-year intervals, coverage is assessed in late July, using visual estimates of cover by species, based on a modified Daubenmire scale.

The effects of burning, mowing, and nitrogen (N) and phosphorus (P) fertilization on the trophic structure of a tallgrass prairie nematode community were examined in a long-term field experiment established in 1986. Nematode densities and trophic composition were determined in October of 1987, 1989, and 1994 following 2, 4, and 9 years of treatment, respectively.

Measurements include rainfall amounts, nitrate (NO3-N), ammonia (NH4-H), soluble reactive phosphate (SRP), and total nitrogen and phosphorus concentrations in bulk precipitation collected at multiple locations.

The Konza burn history data is downloadable by year. Watershed names and codes listed are the current watershed designations (2010). Please note that several watershed designations have changed over the history of Konza. This is inevitable due to changes in research objectives but is problematic for those wanting to discover the full burn history of a given area. In some cases watersheds have simply been renamed to reflect changes in experimental burn treatments (e.g. R20A was formerly 1A). In other cases watersheds have been subdivided or aggregated from smaller watersheds (eg.

To address the potential interactive effects of fire, aboveground biomass removal, and nutrient amendments on above- and belowground responses, a long-term field experiment was initiated in 1986 as part of the Konza Prairie Long-Term Ecological Research (LTER) program.

Data describe soil chemistry collected during the 2017-2021 growing seasons at the Belowground Plot Experiment to assess for legacies. Whole plot-scale nitrogen fertilization at the Experiment ceased in 2017. Four subplots within each historically fertilized plot were set up to continue the annual fertilization treatment for soil chemistry.

This data set is a compilation of data collected by multiple researchers describing nests of 48 bird species from across Konza Prairie. Compiled and edited into consistent format by Emma B. Smith, and included in her Master’s thesis. The goal of this dataset is to compile as much data on bird nests at Konza as possible. This data set includes data from other KNZ datasets CBN01 and PBG05, as well as data contributed by Page Klug, Jim Rivers, John Zimmerman, Bill Jensen, Brett Sandercock, Alice Boyle, Bram Verheijen, Bridget Sousa, Aaron Pearse, Karl Kosciuch, and Scott Hatch.

Data describe the activity of soil extracellular enzymes collected approximately every month in 2015 from the Belowground Plot Experiment. The measured enzymes depolymerize soil organic matter to release labile carbon, nitrogen, and phosphorus. Soil carbon and nitrogen were measured in July 2015 only, since these soil variables are not expected to change monthly.

This project addresses the long-term effects of fire (annual burning or fire suppression), mowing, and nitrogen (N) and phosphorus (P) fertilization on the structure and composition of a tallgrass prairie nematode community during 30 years of experimental treatments.
