Long-Term Ecological Research (LTER)/KBS005: Kellogg Biological Station Plant Community Resource Partitioning Experiment

LTER - Long-Term Ecological Research Program/Kellogg Biological
Station (KBS)

LTER/KBS005 [Summary adapted from the LTER Core Data Set Catalog]:

Results from a set of experimental subplots within selected crop and
successional communities (see KBS004) designed to determine how plants
partition resources and whether crop-weed interactions vary in
response to resource levels. Effects of N fertilizer on community
production and partitioning at the species level determined by
manipulating fertilizer inputs in the historically tilled early
successional community and high chemical input CT and NT corn/ soybean
treatments. Competitive effects examined in the conventionally tilled
(CT), no-till (NT), and poplar treatments by determining how crop
density affects growth and nitrogen uptake in the presence and absence
of competing weeds.

The 1,000 ha W.K. Kellogg Biological Station has been administered by
Michigan State University as a primary research facility since its
1929 deeding to the university by Kellogg. In its early years the
Station was devoted to wildlife, forestry, and soil conservation
research; during the past 20 years a research emphasis on ecology,
production agronomy, and forest genetics has led to well-established
and internationally recognized programs in each of these fields. The
mission of the Station, supported by 10 year-round resident faculty
from several university departments, in addition to campus-based
faculty and visiting scientists, puts a primary emphasis on
maintaining an environment for interdisciplinary research in ecology,
agriculture, and natural resources.

KBS LTER research topics include ecological interactions underlying
the productivity and environmental impact of production-level cropping
systems; patterns, causes, and consequences of microbial, plant, and
insect diversity in agricultural landscapes; gene transfer, community
dynamics and biogeochemical fluxes.
