Different harvest and/or sampling methods are required to quantify these diverse plant communities. All measurements are taken pre-harvest at peak annual biomass for major community components. This generally means physiological maturity for annuals and pre-senescence for perennials. Plant biomass samples are taken from each of the 3 sampling stations within a plot (Fig.1). Note that ANPP is different from yield, which represents some (usually high) portion of ANPP.Aboveground Net Primary Productivity- GLBRC Intensive SitesData Managerhttp://lter.kbs.msu.edu/protocols/117The biofuel cropping systems of GLBRC Experiments range from annual crops to perennial monoculture grasses and mixed communities to poplar trees. Different sampling methods are needed to measure aboveground net primary productivity (ANPP) in these diverse plant communities. In general, plant biomass is sampled for all major community components before harvest at peak annual biomass. This typically means physiological maturity for annuals and pre-senescence for perennials. For the Biofuel Cropping System Experiment (BCSE; Treatments G1-G10), plant biomass is sampled at each of the 3 sampling stations within a treatment plot (see https://lter.kbs.msu.edu/maps/images/glbrc-station-flags.pdf). ANPP sampling in the Scale-Up Experiment (Fields L1-L3 and M1-M4) terminated after the 2016 growing season, but was sampled from 2009 to 2016 at each of the 10 sampling stations within a field (see https://lter.kbs.msu.edu/maps/images/current-glbrc-scaleup-fields.pdf). The location of the sampling quadrat around the sampling station varies annually and quadrat placement is determined by quadrat size and ease for field sampling. ANPP is measured in g/m2/yr and is the sum of the major plant community components of each treatment at their peak biomass.
Note that ANPP is different from agronomic yield, which represents only the harvested portion of ANPP.
Also note the BCSE in Arlington (ARL) was retired at the end of the 2017 growing season. The protocols listed below focus on methods used at KBS; if ARL used different methods, those differences are given at the end of each section.Aboveground Net Primary Productivity- BCSE & Scale-Up ExperimentData Managerhttp://lter.kbs.msu.edu/protocols/156Plant IdentificationData Managerhttp://lter.kbs.msu.edu/protocols/27Just prior to harvest in 2014-2016, we sampled the standing biomass in the continuous corn (G1) and perennial (G5-7 and G9-10) treatments of the GLBRC Biofuel Cropping System Experiment (BCSE) to determine harvest efficiency and losses due to mechanical harvesting and senescence.Harvest EfficiencyData Managerhttp://lter.kbs.msu.edu/protocols/182https://lter.kbs.msu.edu/datatables/202Kellogg Biological Station LTER: Poplar Leaf Litter Biomass (GLBRC082-001)Biomass of leaf litter collected from litter traps in the BCSE poplar treatment (G8).
