Soil samples are taken annually (usually in the Fall) for fertilizer recommendations and analyzed by the Michigan State University Soils Laboratory. The soil samples are taken from the annual treatments T1 though T4 and T6.
Long Term Agroecosystem Research Overview
- Agroecosystem productivity is sustainably enhanced by the development and application of new technologies
- Mitigation and adaptation of agroecosystems to climate change is improved by more accurate predictions of resource responses to system drivers
- Stronger linkages to other long-term research networks improves conservation and environmental quality in agricultural landscapes
- The socio-economic viability of, and opportunities for, rural communities are enhanced through educational outreach by LTAR scientists and collaborators
LTAR Research Sites
Data from the following LTAR sites are presented. They are related to topics such as agricultural sustainability, climate change, ecosystem services, and natural resource conservation at the watershed or landscape scale.
This study provides a gradient of 9 different rates of nitrogen fertilization under rainfed and irrigated conditions. Irrigation began in 2003.
This dataset gives yields from the European Corn Borer Study. The ECB study is a long-term study at the Main Site complex, in which the European Corn Borer is controlled by biological vs. chemical means.
Agronomic Yields on the Main Cropping System Experiment at the Kellogg Biological Station, Hickory Corners, MI (2000 to 2014)
Agronomic yields have been measured on the Biodiversity Study since 2000. Samples are collected from the corn, soy and winter wheat plots before harvest by harvesting a subplot with a plot combine.

Cellulosic Biofuels Diversity Experiment at the Kellogg Biological Station, Hickory Corners, MI (2006 to 2015)
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.
Main Cropping System Experiment at the Kellogg Biological Station, Hickory Corners, MI (1988 to 2015)
This dataset includes information about the LTER main site treatments, agronomic practices carried out on the treatments and approved site use requests.
Resource Gradient Study Management at the Kellogg Biological Station, Hickory Corners, MI (2000 to 2012)

Agronomic Yields in Row Crop Agriculture at the Kellogg Biological Station, Hickory Corners, MI (1989 to 2015)
This data set contains information about agronomic yields for the Main Cropping System Experiment which include treatments 1-4 (corn – wheat – soybean rotations) and after 1994 treatment 6 (alfalfa).
