Description: Elemental composition of Larrea tridentata leaf tissue and Pectocarya recurvata (whole plant) tissue collected from control plots at Desert Fertilization study sites. Most analyses are by ICP-MS except for Sulfur (S), which is typically analyzed by ICP-OES with the instrument type noted in the instrument field.

Description: Composition of annual plants and other study plot characteristics (e.g., base or canopy of perennial plants) at subplots within Desert Fertilization study plots assessed in the spring of 2008. One-meter subplots include locations around a Larrea tridentata plant and locations in the interplant space between shrubs. Composition of plants reflects the relative cover of each plant as a decimal fraction.

Tabular: 632_plant_root_simulator_6beb88101ef5b4ce5fed01b42c744f37.csv
Description: Soil ion concentrations as determined with Plant Root Simulator (PRS®) probes (ion exchange resin membranes). Probes for the analyses of soil anions have a positively-charged membrane to simultaneously attract and adsorb all negatively-charged anions, such as nitrate (NO3-), phosphate (H2PO4-, HPO42-), and sulphate (SO42-), whereas cation probes have a negatively-charged membrane to simultaneously attract and adsorb all positively-charged cations, such as ammonium (NH4+), potassium (K+), calcium (Ca2+), and magnesium (Mg2+).

File: 632_raw_icp_ef6d7c40c37c54020bb1beb9a8adae54.zip
Description: This zipped file contains the raw ICP-MS and ICP-OES data (as XSLM and xls files) pertaining to the analyses of Larrea tridentata leaf tissue and Pectocarya recurvata plant tissue samples. The file Cndep_ICP_MS_02252014.xlsm includes Larrea tridentata leaf tissue data for the years 2009, 2010, and 2013. The file CNDep_Larrea_Metals_Oct2015.xlsm includes Larrea tridentata leaf tissue data for the year 2015. The file Cndep_Larrea_Pecto_10202016.XLSM includes Larrea tridentata leaf tissue data for the spring and fall of 2016, and Pectocarya recurvata plant tissue data for the spring of 2015 and 2016 for a suite of analytes as analyzed by ICP-MS. The file Larrea_S_11032016.xls includes Larrea tridentata leaf tissue data for the spring and fall of 2016, and Pectocarya recurvata plant tissue data for the spring of 2015 and 2016 for sulfur as analyzed by ICP-OES. The calculated concentrations (i.e., not the raw data) are presented in entity 'tissue_icp' that is part of this dataset.
