Long-Term Ecological Research (LTER)/CDR003: Effects of Nutrients on Vegetation at Cedar Creek Natural History Area

LTER - Long-Term Ecological Research Program/Cedar Creek Natural
History Area (CDR)

LTER/CDR003 [Summary adapted from the LTER Core Data Set Catalog]:

This experiment is being conducted within the fenced areas of fields A, B, C,
and D. The purpose of this experiment is to determine the effect of various
nutrients on vegetation. There are eight different nutrients and a control.

The different nutrients are N, P, K, Ca, Mg, Na, H2O, and a combination of
trace metals. There are 36 plots in each field, four replicates of the nine
treatment levels. The plots are 1 m x 4 m and are laid out in a 4 x 9 grid.

The grid was divided into quarters and treatments were assigned with a
randomized block design.

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 (CCHNA) 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.
