Soil chemistry and nutrient distribution in long-term NPP plots at the Jornada Basin LTER site, 1989

This dataset contains soil nutrient and chemistry data from soils
collected in 1989 at the 15 long-term NPP study sites at the Jornada
Basin LTER site. The study sites were selected to represent the 5
major ecosystem types in the Chihuahuan Desert (upland grasslands,
playa grasslands, mesquite-dominated shrublands,
creosotebush-dominated shrublands, tarbush-dominated shrublands).
For each ecosystem type, three sites were selected to represent the
range in variability in production and plant diversity; thus the
locations are not replicates. In 1989, replicate soil samples were
collected at multiple depths from buffer zones surrounding the
long-term vegetation monitoring plots. Nutrient and chemical
analyses were subsequently performed on these soils, and the data
here include inorganic nitrogen, phosphorus, pH, cation
concentration, percent organic carbon, and other variables. This
dataset is complete.
