Current year’s biomass is sorted and bagged by species/category in the field. Surface litter was collected and bagged. Robel pole assessments of plant density in prairie and switchgrass fields are done in four cardinal directions from the center of the harvested area before clipping begins. See Robel Pole method.Data Managerhttp://lter.kbs.msu.edu/protocols/126Location: Extensive sites of the GLBRC Biodiversity Experiment Background: This sampling protocol is an additive radii modification of R. H. Whittaker’s plant diversity sampling method (1). The sample areas are nested circles based at a fixed central point. Species composition is determined at 3 scales (See Figure 1)— 1 m2, radius = 0.56 m 10 m2, radius = 1.78 m 100 m2, radius = 5.64 m Area of Circle = π r2; π = 3.14 Four non-overlapping stations are sampled in each field site. The location of the stations is established by the GLBRC insect diversity assessment team and marked with a stake and tall flag. This flag is the central anchor point for the nested circle areas.Data Managerhttp://lter.kbs.msu.edu/protocols/125Background: The Robel Pole Method can be used to estimate the amount of standing biomass present at the time of measurement. Because the bird diversity team of the GLBRC Biodiversity Experiment used the Robel Pole method to assess plant density at extensive sites, the same method was employed by the primary production and plant species composition team in order to establish the correlation between Robel Pole plant density and biomass.Data Managerhttp://lter.kbs.msu.edu/protocols/127Background: This sampling protocol is based on the method used by University of Wisconsin for GLBRC floral sampling (Intensive Week Protocols.pdf, received from Ben Werling 7/30/10). Species composition is assessed in ten 1 m2 quadrats along a transect adjacent and parallel to the station flags and outside of the nested circles method area. One transect assessment is done in each field site.Data Managerhttp://lter.kbs.msu.edu/protocols/128 The LTER GPS units are used for recording the locations of microplots, experiments,instrumentation, plot corners, sampling sites, events and many other LTER features that need to be mapped in the LTER GIS. They are also used to navigate back to these locations. These instructions detail how to use the GPS in normal conditions and more challenging situations and also how to use the software in the lab to download, upload and convert data. When using the Trimble XRS Pro GPS with the Omnistar real-time correction service, we can expect submeter accuracy (+ 70 cm or better). Data Managerhttp://lter.kbs.msu.edu/protocols/49The LTER GPS units are used for recording the locations of microplots, experiments, instrumentation, plot corners, sampling sites, events and many other LTER features. They are also used to navigate back to these locations and to navigate to new locations whose coordinates have been uploaded to the GPS. When using the Trimble XRS Pro GPS with the Omnistar real-time correction service or the internal Coast Guard beacon we can expect submeter accuracy (approximately + 20 to +70). We keep the Omnistar real-time correction service on the GPS I data logger and the Coast Guard beacon on GPS II. We can always start the Omnistar service on GPS II if needed for $400/year. We switched to the Coast Guard beacon from 25 June 2008- 3 August 2009 but we went back to the Omnistar service because the connection to the Coast Guard beacon wasn’t dependable . We are in a weak spot for the beacon and also in high humidity conditions it is more difficult to receive the signal. When we were able to get the connection the resolution was similar (5 cm – 30cm less accurate than Omnistar during the testing periods).Data Managerhttp://lter.kbs.msu.edu/protocols/106Surface (0-25 cm) soil samples are typically collected in the fall, composited by plot, and sent to an analytical laboratory for analysis and for nutrient and liming recommendations for field crops. Analyses include pH, lime index, phosphorus, potassium, calcium, magnesium, and cation exchange capacity. Samples collected in the fall provide liming and fertilizer recommendations for the following year. Deep cores (0-100 cm) are collected every 5-10 years and samples are analyzed separately by depth interval to monitor longer-term changes in composition with depth. Sampling frequency: Depends on experiment and research objective.

At each site, standing plant biomass was clipped to the ground and surface litter was collected from a measured area (see protocol). Biomass was sorted into broad groups: corn ears, corn stalks, switchgrass, big bluestem, indiangrass, other grass, forbs and surface litter. Biomass was dried and weighed.
