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.

Description: Biomass (g) of annual plants harvested from subplots within Desert Fertilization study plots. One-meter subplots include locations around a Larrea tridentata plant and locations in the interplant space between shrubs. Material is harested from 0.25 square meter quadrats within each subplot. All harvests occur during the spring.

Tabular: 632_plant_root_simulator_5ebc781cc4444ee517f828603f10dece.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+).
