The experiment consists of six different biofuel cropping systems (a.k.a. treatments; G5-G10; including switchgrass, miscanthus, native grasses, hybrid poplar, early successional, and restored prairie, respectively) plus an historical vegetation control (G11), replicated in each of 4 blocks (R1-R4) at each site. Split-plot treatments were initiated in 2014-2016 to examine the effect of nitrogen fertilization [plus_n (+N) vs control (0N)] on all cropping systems.

Six potential biofuel cropping systems (a.k.a. treatments; G5-G10 including switchgrass, miscanthus, native grasses, poplar, early successional, and restored prairie, respectively) from the GLBRC Biofuel Cropping Systems Experiment (BCSE) plus an historical vegetation control (G11) are replicated in each of 4 blocks (R1-R4). Split plot treatments were initiated in 2014-2016 to examine the effect of nitrogen fertilization [plus_n (+N) vs control (0N)] on all cropping systems. For more Information on site details, plot layout, and cropping systems see Marginal Land Experiment. For a taxonomic description of soils from each site, see Kasmerchak and Schaetzl (2018).
Both surface and deep-core soil samples are taken and may be analyzed for bulk density, total carbon and nitrogen, inorganic nitrogen, and for agronomic analysis and fertilizer/liming recommendations. Canopy species composition, annual net primary production (ANPP), and dry matter yields are measured in each of the cropping systems. Different methods are needed for ANPP and/or yield measurements of the poplar (G8) and historical vegetation (G11) treatments. Search for GLBRC Marginal land sites under Areas in the ag log for more specifics on sampling/harvesting equipment and procedures.
Each site has a weather station that records 5-minute observations of on-site conditions. Water profilers are installed in three replicates of each of the switchgrass (G5), poplar (G8) and restored prairie (G10) treatments; measurements are recorded at 0, 30 and 60 cm depths.
In 2018, a rainfall exclusion experiment was established in the fertilized split plot of the switchgrass (G5) treatment to examine the effects of drought on switchgrass For more information, see the Marginal Land Rainfall Exclusion Experiment protocol.
Note that Block 1 at the Wisconsin Central – Hancock site was retired in 2015. Also, the entire Wisconsin South – Oregon site was retired after the 2018 growing season due to high soil fertility and the maintenance, sampling, harvest and analysis of the remaining Wisconsin sites was transferred from UW staff to MSU staff.GLBRC Marginal Land Experiment – SamplingData Managerhttp://glbrc.kbs.msu.edu/protocols/181Soil total carbon and nitrogen as well as the ratio of C:N are important attributes of soil fertility. Both total C and N are measured by a combustion method that does not differentiate between organic and inorganic forms of the elements. In most soils, inorganic N is a tiny fraction of total N so total N is synonymous with organic N. Inorganic C, on the other hand, can be a significant portion of total C in soils with carbonate minerals. Extensive testing of KBS surface soils has shown soil inorganic C to be non-detectable; thus total C in KBS surface soils is synonymous with total organic carbon (TOC).
However, carbonates may still be present in deep or recently limed soils, which must be tested for inorganic carbon and, if present, the carbonates removed via acid fumigation (described below) prior to total C analysis. Inorganic C can also be analyzed separately via the inorganic C protocol.
To measure total C and N, subsamples of dried, finely ground soil are weighed into small foil capsules that are combusted in an automated CHN analyzer that measures the amount of released CO2 and N2 by gas chromatography. Final values are expressed as the percentage of carbon or nitrogen in dry soil. If inorganic C has been confirmed to be absent, removed, or analyzed separately and subtracted, values can be expressed as total organic C.
Sampling frequency depends on experiment and research objectives. Since 2001, soils of the LTER Main Cropping System Experiment are analyzed for total C and N as part of the decadal deep soil core (whole profile) sampling program, usually in late fall of wheat years.Soil Total Carbon and NitrogenData Managerhttp://lter.kbs.msu.edu/protocols/37Soil bulk density is a measurement of the dry mass of soil per unit soil volume (g/cm3) and thus includes the combined volume of solids and pores that may contain gases or water, or both. Bulk density can affect many soil processes, such as water passage, heat transfer, aeration and root growth. It is also a necessary factor to convert mass-based units to area-based units.
This protocol describes bulk density analyses associated with deep (1 m) soil cores sampled at approximate 5-10 year intervals to examine changes in soil carbon with depth. Cores are delineated into soil sections and bulk density is determined either by depth interval or by soil horizon (MCSE in 2008). For each core section or interval, dried subsamples are also pulverized and sampled for carbon and nitrogen analysis, and the remainder or a portion thereof is archived.
Sampling frequency: Usually every 5-10 years Soil Bulk Density - Deep CoresData Managerhttp://lter.kbs.msu.edu/protocols/110Ammonium (NH4 ) and nitrate (NO3-) are the predominate forms of inorganic N in soils; their availability affects rates of N transformation, plant uptake, and N leaching. To measure the nutrient pool of NH4 and NO3- in soils, a subsample of a fresh, sieved composite sample is extracted, filtered, and the extract then analyzed using colorimetric techniques. Concentrations of NH4+ and NO3- are typically expressed as element mass of N per gram of dry soil, but conversion to an areal basis is possible if the soil bulk density and sample depth are known.
Sampling frequency: Depends on experiment, time of year, and research objective. Soil inorganic N is routinely measured as part of our LTER and GLBRC soil sampling programs.Soil Inorganic NData Managerhttp://lter.kbs.msu.edu/protocols/33The amount of water or moisture in a given mass of soil is highly variable and is important to measure in field studies because it affects microbial activity, nutrient movement, and plant growth. To measure soil moisture content by the gravimetric method, a subsample of a fresh, sieved composite sample or a fresh soil core is weighed, oven dried until there is no further mass loss, and then reweighed. The moisture content is expressed as mass of water per mass of dry soil.
Sampling frequency: Depends on experiment and research objective. Soil moisture is routinely measured as part of our LTER core soil sampling for inorganic N, N mineralization, and greenhouse gas fluxes.Soil Moisture ‒ GravimetricData Managerhttp://lter.kbs.msu.edu/protocols/24https://lter.kbs.msu.edu/datatables/438Kellogg Biological Station LTER: Agronomic Soil Chemistry (GLBRC094-003)Deep core (to 1 m) and surface (typically 0-25 cm) soil samples are taken periodically and sent to an analytical laboratory for fertilizer/liming recommendations and analyzed for pH, lime index, phosphorus, potassium, calcium, magnesium, cation exchange capacity and, depending on laboratory, organic matter.
