Soil Inorganic Nitrogen on the Main Cropping System Experiment at the Kellogg Biological Station, Hickory Corners, MI (1989 to 2018)
Dataset AbstractMeasurement of soil inorganic nitrogen began in 1989 for all treatments on the LTER Main Site and 1993 on the Successional and Forest sites. Ammonium and nitrate are analyzed twice monthly or monthly during the growing season on baseline soil samplings. Additional datasets from the Baseline Soil Samplings include soil moisture, total N and total C.original data source http://lter.kbs.msu.edu/datasets/24
Soil moisture determinations by Electrical Resistivity (ERT) Experiment at the Kellogg Biological Station, Hickory Corners, MI (2009)
Dataset AbstractLarge-scale conversion of croplands to perennial biofuel crops could substantially impact regional water, nutrient, and C cycles due to the longer growing seasons and differences in rooting systems compared with most annual crops. However, these differences in crop water use are not well known due to the limited tools available to nondestructively study the spatiotemporal patterns of root water uptake in situ at field scales. Geophysical imaging tools such as electrical resistivity (ER) reveal changes in water content in the soil profile.

Insect Population Dynamics on the Main Cropping System Experiment at the Kellogg Biological Station, Hickory Corners, MI (1989 to 2019)
Dataset Abstract Plant dwelling insect occurrence in the LTER main site (all treatments) of the KBS-LTER has been recorded since 1989 and in the successional and forest sites since 1993. The effort has focused on characterizing the temporal and spatial abundance and diversity of a set of insects representative of a higher order insect trophic level, the herbivore predators. The insect database contains more than 400,000 records and consists of counts of adult insects of fourteen species of Coccinellidae, one species of Chrysopidae, and one species of Lampyridae from 30 sample sites in each of the seven treatments in the LTER Main Site. The standard method used to measure these organisms is a yellow sticky trap. Sampling is conducted weekly during the growing season as described in the sampling protocol. original data source http://lter.kbs.msu.edu/datasets/26
Plant Carbon and Nitrogen Content at the Kellogg Biological Station, Hickory Corners, MI (1989 to 2018)
Dataset Abstract This dataset includes total carbon and total nitrogen measured for plants from the LTER Main Site and the Successional and Forested sites. Total C and N are analyzed at peak biomass for a given treatment. In some systems with multiple harvests or complex communities that have peaks occurring at different times of the year, measurements are taken at multiple times per year. Samples are combusted and measured on a CHN analyzer. original data source http://lter.kbs.msu.edu/datasets/32
Resource Gradient Experiment at the Kellogg Biological Station, Hickory Corners, MI (1999 to 2019)
Dataset Abstract This study provides a gradient of 9 different rates of nitrogen fertilization under rainfed and irrigated conditions. Irrigation began in 2003. Corn was grown from 2000-2005 and subsequently the crop rotation (wheat, corn, soybean) followed the crop of the LTER main site. Nitrogen applications differ by crop after 2007. The experiment was moved to its current location on the LTER main site in 2005. The experiment location/history are explained here. Plots are 5×30 m arranged in each of 4 replicate blocks . Crop yields, nitrous oxide and soil temperature, moisture and nitrogen data are available for this study. original data source http://lter.kbs.msu.edu/datasets/36
Main Cropping System Experiment Field Logs and treatment descriptions at the Kellogg Biological Station, Hickory Corners, MI (1988 to 2020)
Dataset Abstract This dataset includes information about the LTER main site treatments, agronomic practices carried out on the treatments and approved site use requests. Most long-term hypotheses associated with the KBS LTER site are being tested within the context of the main cropping systems study. This study was established on a 48 ha area on which a series of 7 different cropping systems were established in spring 1988, each replicated in one of 6 ha blocks. An eighth never-tilled successional treatment, is located 200 m off-site, replicated as four 0.06 ha plots. Cropping systems include the following treatments: T1. Conventional: standard chemical input corn/soybean/wheat rotation conventionally tilled (corn/soybean prior to 1992) T2. No-till: standard chemical input corn/soybean/wheat rotation no-tilled (corn/soybean prior to 1992) T3. Reduced input: low chemical input corn/soybean/wheat rotation conventionally tilled (ridge till prior to 1994) T4. Biologically based: zero chemical input corn/soybean wheat rotation conventionally tilled (ridge till prior to 1994) T5. Poplar: Populus clones on short-rotation (6-7 year) harvest cycle T6. Alfalfa: continuous alfalfa, replanted every 6-7 years (converted to switchgrass in 2018) T7. Early successional community: historically tilled soil T8. Mown grassland community: never-tilled soil. For specific crops in a given year see the Annual Crops Summary Table. In 1993 a series of forest sites were added to the main cropping system study to provide long-term reference points and to allow hypotheses related to substrate diversity to be tested. These include: TCF. Coniferous forest: three conifer plantations, 40-60 years old TDF. Decidious forest: three deciduous forest stands, two old-growth and one 40-60 years post-cutting TSF. Mid-successional forest: three old-field (mid-successional) sites 40+ years post-abandonment. All share a soil series with the main cropping system treatments, and are within 5 km of all other sit
Aerial Photographs of the KBS LTER and Environs at the Kellogg Biological Station, Hickory Corners, MI (1938 to 2020)
Dataset Abstract Aerial photography is considered an important management tool in agriculture. Aerial photography allows researchers to detect spatial variability and understand the causes of the variability such as planter skips, drought stress, weeds and water erosion. In agricultural research it allows researchers to differentiate healthy vegetation from unhealthy and access plant biomass and moisture levels. The photographs are also useful to document trends and changes in the landscape. original data source http://lter.kbs.msu.edu/datasets/44
Forest Increment Survey at the Kellogg Biological Station, Hickory Corners, MI (1991 to 2019)
Dataset Abstract In 1998, a new protocol was instituted for measuring the diameters of every tree greater than 5 cm dbh in the coniferous and deciduous forest plots. Trees are usually measured in January. Exponential equations are used to estimate tree mass for each year. The goal is to estimate wood production for any given time period (usually one year) as the difference between two estimates of mass. original data source http://lter.kbs.msu.edu/datasets/48

Cellulosic Biofuels Diversity Experiment at the Kellogg Biological Station, Hickory Corners, MI (2006 to 2017)
Dataset Abstract The Cellulosic Biofuels Diversity Experiment is an additional long-term study located within the LTER Main Site complex, in which a series of 12 different cropping systems vary in species makeup and nitrogen input. Treatments include continuous corn, corn-soybean, two variations of switchgrass fertilized differently, a C3 – C4 grass mix, and prairie grasses native to Michigan with different numbers of species. Switchgrass varieties are Cave-in rock (commercial non-native) and Southlow commercial native). Prairie grasses include switchgrass (Panicum virgatum), big bluestem (Andropogon gerardii), little bluestem (Schizachyrium scoparium), and Indian grass (Sorghastrum nutans), Treatment plots are 9.1 by 27m (30 × 40 feet) replicated in each of 4 randomized blocks.
