Microbial Biomass Dynamics at the Kellogg Biological Station, Hickory Corners, MI (1989 to 1996)
Dataset Abstract The purpose of these studies is to determine patterns of microbial biomass dynamics in crop, successional and forest communities. This project consists of two studies involving microbial biomass determination in soil samples taken from the Main Cropping System Experiment (KBS004): Chloroform Fumigation-Incubation; Soil Microbial Biomass C and N, and Epifluorescence Microscopy and Image Analysis; Soil Microbial Biovolume and C. The data for both studies are generated from subsets of the same soil samples, collected from treatments 1 – 8, CF, DF, and SF. See the descriptor (KBS004) for treatment descriptions. Samples are collected approximately monthly (during ice-free conditions) or annually (varies by year) from 5 sampling stations in each of 6 replicate plots per treatment; exceptions are treatment 8 (four reps), and treatments CF, DF, and SF (three reps each). For experiment descriptions, protocols, and data, see individual datasets. Samples were collected by K. Klingensmith in 1989 and by S. Halstead in other years. D. Harris performed lab analysis, data entry, data analysis, and data submission. Original data files not available; contact the LTER data manager with questions. The data currently available was derived from web-based files which were last reviewed by D. Harris on 10-01-1997 and may be available from archives. original data source http://lter.kbs.msu.edu/datasets/14
Plant biomass collection on the Biodiversity Experiment at the Kellogg Biological Station, Hickory Corners, MI (2001 to 2011)
Dataset Abstract The biodiversity gradient experiment is an additional long-term study located within the LTER Main Site complex, in which a series of 21 different experimental treatments vary in plant species diversity. Treatments range from bare soil to single-crop rotations to multiple-crop rotations to annually fallowed fields with early successional plant communities. Plant species richness thus varies from 0 to >15 in any given 3-year rotation cycle. Treatment plots are 9.1×27.4 meters (30×90 feet) replicated in each of 4 randomized blocks. The study site was established in 2000. original data source http://lter.kbs.msu.edu/datasets/112

Soil Total Carbon and Total Nitrogen on the Main Cropping System Experiment at the Kellogg Biological Station, Hickory Corners, MI (1989 to 2001)
Dataset Abstract Soil carbon and nitrogen are presented as % elemental carbon and nitrogen (g C or N / 100 g soil) for the sampling depth of the specific sampling date unless indicated otherwise. Samples were taken with either a 2.5 cm diameter soil corer (sampling by soil depth) or a 10 cm diameter Giddings probe (sampling by soil profile). See Baseline Soil Sampling protocol for general sampling information. For specific sampling details for a particular date, see Soil Sampling Field Log. Soil samples are sieved to 4mm and composited by plot. Soil % elemental carbon and nitrogen values are determined by sample combustion and subsequent TCD gas chromatography, using a Carlo Erba automated CHN analyzer as described in the sampling protocol. original data source http://lter.kbs.msu.edu/datasets/27
Soil Bulk Density on the Main Cropping System Experiment. at the Kellogg Biological Station, Hickory Corners, MI (1995 to 1996)
Dataset Abstract Soil bulk density is used to convert water content by weight to water content by volume and for calculating porosity and void ratio. Bulk density has an inverse relationship with soil structure and soil porosity. Bulk density data were collected using an excavation procedure found in the sampling protocols. Bulk density data are available from the forest sites in 1995 and all sites on the LTER Central Experiment in 1996. original data source http://lter.kbs.msu.edu/datasets/29

Baseline Spatial Variability Study at the Kellogg Biological Station, Hickory Corners, MI (1988)
Dataset Abstract A spatial variability study conducted across the LTER Main Site area (45 ha) at KBS prior to dividing the site into 1-ha experimental plots. During the 1988 growing season a stratified unaligned sampling scheme was used to collect 400-600 geo-referenced samples across the site (uniformly planted to a single variety of soybeans) for: geomorphological characteristics (microtopography, soil horizon depths, bulk density, texture); soil chemical characteristics (pH, NO3, NH4, total C, total N, moisture, inorganic P, trace metals); soil biological characteristics (N mineralization potentials, microbial biomass C, microbial biomass N, fungal/bacterial ratios, nematodes and other soil invertebrates; seed bank size); plant weed species abundance, weed biomass at peak standing crop); and insect characteristics (major pest and predator species). Most soil samples were taken before crop emergence, plant phenology samples were taken throughout the growing season, biomass samples were taken at physiological maturity, and insect samples were taken continuously. Dried soil and plant samples are archived for potential future analysis. original data source http://lter.kbs.msu.edu/datasets/6

Living Field Laboratory at the Kellogg Biological Station, Hickory Corners, MI (1992 to 2012)
Dataset Abstract The Living Field Laboratory is a long-term rotation study established in 1993 under the direction of Emeritus Professor Dr. Richard Harwood to evaluate the benefits of cover crops (as green manure) and/or the addition of composted dairy manure in two integrated systems compared to a conventional and an organic system. The LFL accommodates every entry point of the crop rotation each year and has a factorial design that allows for the comparison of a number of interactions. These interactions include: differences in N management, rotation effects, and cover crops. From 1993 through 2005, the rotation consisted of corn (Zea mays L.)/corn/soybean (Glycine max)/wheat (Triticum aestivum) vs. continuous corn. During this period, crimson clover (Trifolium incarnatum L.) was seeded to 1st yr. corn, 2nd yr corn was in rye grass (Lolium multiflorum), soybean had no cover, and red clover (Trifolium pretense L.) was frost-seeded into wheat. In 2006, under the direction of Dr. Sieglinde Snapp and through consultation with a farmer advisory group, the rotation was shortened to a 3 yr rotation of corn/soybean/wheat vs. continuous corn. The remaining plot in each management system was converted to a 2 yr rotation of corn/soybean. Cereal rye (Secale cereale) is now planted after corn regardless of crop rotation. Cereal rye follows soybean in the 2-yr rotation. Red clover is frost-seeded into wheat. The management systems are: Conventional, Integrated Fertilizer and Integrated Compost. Weed management is identical across systems, and nitrogen fertilizer management adjusted to take into account soil N availability and balance nitrogen inputs across treatments. The cover crop is present as a split plot (plus minus) within each system. The split-plot cover crop treatment was established in 1993 in Integrated Fertilizer and in Integrated Compost, while the split-plot cover crop treatment was established 14 years later in 2007 in the Conventional treatment, to allow a comp
Soil Carbon and Nitrogen Deep Core Surveys at the Kellogg Biological Station, Hickory Corners, MI (2001 to 2013)
Dataset Abstract An LTER project goal is to periodically collect and analyze deep soil cores for the main site treatments and successional and forest sites.

Water Chemistry in Streams, Lakes Wetlands and Groundwater near the KBS LTER at the Kellogg Biological Station, Hickory Corners, MI (1996 to 2017)
Dataset Abstract Water chemistry is measured in diverse surface waters and in two water supply wells in the vicinity of the KBS LTER. This dataset includes sites sampled over time (streams, wells, some wetlands) as well as wetland sites sampled once or a few times. A separate dataset includes soil water chemistry sampled from the LTER treatments. original data source http://lter.kbs.msu.edu/datasets/50
Distribution and Composition of the Seed Bank at the Kellogg Biological Station, Hickory Corners, MI (1990 to 2008)
Dataset Abstract The distribution and composition of the weed seed bank in treatments 1-7 of the LTER main site is periodically (every 3-6 years) evaluated using elutriation and seed counting methods. The goal is to determine: how well the seed bank predicts weed abundances and composition in subsequent years, and how changes in disturbance (tillage) and plant species (cropping systems) affect the bank. Composite soil samples to two depths are periodically elutriated to determine seed densities, species composition, and viabilities of seven target species which are dominant on the site. original data source http://lter.kbs.msu.edu/datasets/9
