County, State, and Regional Yields at the Kellogg Biological Station, Hickory Corners, MI (1887 to 2014)
Dataset Abstract County, state, and regional yields are not a product of KBS LTER research, but are scavenged from public sources such as http://www.nass.usda.gov/Data_and_Statistics/Quick_Stats/index.asp and made available here for the convenience of KBS researchers. Yields from KBS treatments may be interpreted in the context of local and regional yields.

Comprehensive Soil Water Chemistry at the Kellogg Biological Station, Hickory Corners, MI (1999 to 2003)
Dataset Abstract Soil water samples are collected every other week during the growing season from treatments 1-7 (replicates 2-4) and the successional and forest sites using Prenart soil water samplers (sometimes referred to as lysimeters). Three sampling stations are located in each treatment and are grouped in this analysis. In this dataset, the following chemical variables were measured from 1999-2005: Ca, Mg, Na, K, NO3, total alkalinity, Cl, SO4, NH4,PO4, DOC, specific conductance, total dissolved phosphorus and Si. See also the dataset entitled Soil Water Nitrate on the Main Cropping System Experiment which covers a longer time period. See the following reference for methods: Hamilton,S.K., A.L. Kurzman, C.Arango, L. Jin, and G.P. Robertson. 2007. Evidence for carbon sequestration by agricultural liming.

Trace gas on the Resource Gradient Study at the Kellogg Biological Station, Hickory Corners, MI (2001 to 2003)
Dataset Abstract This study provides a gradient of nitrogen fertilization under rainfed and irrigated conditions. Nitrogen applications range from 0 to 291 kg N/ha . Plots are 5×30 m arranged in each of 4 replicate blocks. The crop rotation (wheat, corn, soybean) follows the pattern of the main site. The study started in 2002 as a rainfed only study on the south end of the main site. In 2005 a new rainfed and irrigated study was started at the south end of the lysimeter field. The original study site was discontinued in 2006. Crop yields, nitrous oxide and soil temperature, moisture and nitrogen data are available for this study. Treatments are numbered as follows: 1 = 0 kg N/ha, 2= 34 kg N/ha, 3= 67 kg N/ha, 4= 101 kg N/ha, 5= 134 kg N/ha, 6= 168 kg N/ha, 7 = 202 kg N/ha, 8= 246 kg N/ha, 9= 291 kg N/ha. original data source http://lter.kbs.msu.edu/datasets/79
Hamilton-KBS lake chemistry database, Hickory Corners, MI 1998-2011
This dataset contains water chemistry measurements for lakes sampled near the Michigan State University Kellogg Biological Station in Hickory Corners, MI (n=139 lakes). Lake chemistry and chlorophyll samples were collected using an integrated tube sampler of the entire epilimnion (epilimnion depth was determined based on temperature profile) with sampling occuring from May-October with multiple sampling events per year. Samples were collected from 1998-2011, with no samples collected for several years in the mid-2000s. The data prior to 2010 were primarily collected by university researchers but beginning in 2010 sampling was undertaken by a graduate student funded by the Gull Lake Quality Organization (GLQO) to support monitoring of Gull Lake and its inflow streams. Lake samples were processed in the lab of Steve Hamilton, Michigan State University Kellogg BIological Station researcher.

Ecological stress memory in wood architecture of two Neotropical hickory species from central-eastern Mexico
<p>Drought periods are major evolutionary triggers of wood anatomical adaptive variation in Lower Tropical Montane Cloud Forests tree species. We tested the influence of historical drought events on the effects of ecological stress memory on latewood width and xylem vessel traits (vessel density, vessel grouping index, hydraulic diameter, and percent conductive area) in two relict hickory species (<em>Carya palmeri</em> and <em>Carya myristiciformis</em>) from central-eastern Mexico. We hypothesized that latewood width would decrease during historical drought years, developing correlations between growth and hydric stress conditions, and that during past tree growth, moisture stress would imprint on wood anatomical traits between successive drought events. We analyzed latewood anatomical traits that developed during historical drought and pre- and post-drought years in both hickory species. We found that repeated periods of hydric stress left climatic signatures for annual latewood growth and xylem vessel traits that are essential for hydric adaptation in tropical moist tree species. Our results demonstrate the existence of cause‒effect relationships in wood anatomical architecture and highlight the ecological stress memory linked with historical drought events. Thus, combined time-series analysis of latewood width and xylem vessel traits is a powerful tool for understanding the ecological behavior of hickory species.</p>
