Elevation of MCSE Baseline Study — Research Context

Elevation in 1988 at an array of geo-referenced points across the LTER Main Site prior to establishment of the MCSE.

This datatable is part of the Baseline Spatial Variability Study—Main Cropping System Experiment dataset.

This dataset contains the results of a spatial variability study conducted across the KBS LTER Main Site (48 ha) prior to establishment of the 1-ha treatment plots of the Main Cropping System Experiment (MCSE). During the 1988 growing season, the site was uniformly planted to a single variety of soybeans and a stratified unaligned sampling scheme was used to collect 400-600 geo-referenced samples across the site. Samples were analyzed for:

  1. geomorphology (elevation, soil bulk density and texture);
  2. soil chemistry (moisture, pH, inorganic N, total C and N);
  3. soil biology (microbial biomass C, respiration, and population size; N mineralization potentials; nematode counts by feeding type; seed bank);
  4. primary production (soybean biomass, soybean C and N).

Most soil samples (0-15 cm) were taken before crop emergence; plant biomass samples were taken at physiological maturity. Dried soil and plant samples were archived for potential future analysis.
