Soil chemistry and nutrient distribution in long-term NPP plots at the Jornada Basin LTER site, 1991

This dataset contains soil nutrient and chemistry data from soils
collected in 1991 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 fall of 1991, replicate soil
samples were collected at multiple spatial grid designs in the
biomass plots of the long-term vegetation monitoring plots. Nutrient
and chemical analyses were subsequently performed on these soils,
and the data here include total nitrogen, pH, gravimetric water
content, and other variables. This dataset is complete.
