To determine the nutrient efficiency of trees grown under fertilized (subplots) and unfertilized (main plots) conditions, leaf samples were collected at the peak of the growing season (~mid-July) and analyzed by the MSU Soil and Plant Nutrient Laboratory for several plant nutrients (aluminum, copper, iron, manganese, zinc, boron, sodium, calcium, magnesium, potassium, phosphorus, sulfur). The carbon and nitrogen contents of leaves were measured at KBS using a CHN analyzer.Poplar Leaf Nutrient AnalysisData Managerhttp://lter.kbs.msu.edu/protocols/155https://lter.kbs.msu.edu/datatables/338Kellogg Biological Station LTER: Poplar Leaf Tissue Chemical Analyses (GLBRC091-001)Comprehensive chemical analyses of poplar (G8) leaf tissue sampled occasionally from fertilized main plots and unfertilized subplots to assess nutrient status. As of August 2013, the main section had been fertilized only once in June 2010 with ammonium nitrate (156 kg N/ha or 140 lbs N/acre). Carbon and nitrogen were measured by the KBS LTER lab; all other analyses were performed by the Michigan State University Soil and Plant Nutrient Laboratory.

Samples are composited by sample type and replicate (across stations). Samples from annual crop treatments include grain and stover fractions and a combined sample of non-crop species. From 2008-2017, ANPP samples of perennial crops were sorted to species: analyses of monoculture perennial treatments include crop (switchgrass and miscanthus) plus a combined sample of all additional species (“unsorted”); analyses of mixed perennial treatments include the top three species by weight and an aggregate sample of all remaining species. Since 2018, ANPP samples of perennial treatments are left “unsorted” and analyzed as such.Total+Carbon+and+Nitrogen+Content+at+Peak+Biomas.csvNone281\ncolumn,no"\https://data.sustainability.glbrc.org/datatables/414.csvyearyear the sample was collectedYYYY11987-4-18sample_datedate the plants were collectedYYYY-MM-DD11987-4-18treatmentexperimental treatmentexperimental treatmentreplicatereplicate nested within treatmentreplicate nested within treatmentspeciesplant speciesplant speciesfractionplant part analyzedplant part analyzedmicroplotmicroplot microplot carbonpercent carbongramsPerHectogramrealnitrogenpercent nitrogengramsPerHectogramrealhttps://lter.kbs.msu.edu/datatables/469Kellogg Biological Station LTER: Total Carbon and Nitrogen Content at Harvest (GLBRC091-004)Total carbon and nitrogen content of plant samples collected at harvest from all BCSE treatments (G1-G10).
