Title: Long-Term Ecological Research (LTER)/CDR012: Effects of NH4NO3 and pH on Microorganism Populations (SORG) at Cedar Creek Natural History Area
Description:
Abstract:
LTER - Long-Term Ecological Research Program/Cedar Creek Natural History Area (CDR) LTER/CDR012 [Summary adapted from the LTER Core Data Set Catalog]: The purpose of this experiment is to measure the effect of NH4NO3 addition and different levels of pH on microorganism populations. The experiment is located in field B. This experiment was laid out as a full factorial design with three nitrogen levels and four pH levels. The nitrogen levels are E, G, and I as defined in NUTRADD.DOC in the "microplot" category. The pH levels strived for are 4.0, 5.5, 6.5, and controls. The experiment has four replicates. The treatments were randomly assigned to the 48 plots. The plots are 4 m x 4 m and are laid out in a 6 x 8 grid. Proprietary limits: Investigators have priority over data for five years, but are interested in collaboration for novel comparisons before then. The Cedar Creek Natural History Area (CCNHA) is a 2200 hectare experimental ecological reserve operated by the University of Minnesota in cooperation with the Minnesota Academy of Sciences. CCNHA is located in Anoka and Isanti Counties north of Minneapolis/St. Paul. The site was established in 1940, was designated a National Natural Landmark by the National Park Service in 1975. In 1977 it was included as an Experimental Ecology Reserve in a proposed network, and in 1982 it was one of 11 sites in the U.S. selected by the National Science Foundation for funding of LTER.
