Long-Term Ecological Research (LTER)/CDR013: Phenology of Fertilization (PHEN) at Cedar Creek Natural History Area
Entry ID: LTER_CDR013

[ Get Data ]

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

LTER/CDR013 [Summary adapted from the LTER Core Data Set Catalog]:

The purpose of this experiment is to determine the effects of adding
different levels of NH4NO3 at different times during the growing
season. This experiment is being conducted inside the fenced areas of
fields A and B. See CDR001 for description of fence construction.
There are seven treatments: six combinations of three fertilization
dates and two nitrogen levels, and one control. There are five
replicates of each treatment for 35 plots in each field. The nitrogen
levels are E, G, and I and are defined in NUTRADD.DOC in the
"microplot" strategy. The times of fertilization are roughly May,
June, or July. The plots are laid out in a 5 x 7 grid and are 1.5 m x
3.5 m in area. Aisles are 1 m wide in field A and 0.75 m wide in
field B.


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.
