EDI Staging Environment
Soils were sampled at the Net Primary Productivity (NPP) sites on the Jornada Basin LTER (see package knb-lter-jrn.20020450 and other associated packages). The NPP sites include 15 total sites, with 3 sites representing each of the five dominant vegetation types (mesquite, grassland, playa, creosote, tarbush). For this soil sampling project, at 14 of 15 sites a grid of 70 by 70 meters was laid out. Within this grid, 49 plots of 10 by 10 meters were placed and labeled (numbered) in serpentine design. The exception was the playa college site where, 48 plots of 10 by 10 meters were laid out in three long rows of 16 plots per row. At all plots a soil sample of 0-10 cm depth was taken 1 meter from the northeast marker bar at a diagonal (heading toward the southwest marker). At one site representing each five vegetation type another set of 49 soils (#101-149) was taken from within one of the 10 by 10 meter plots. These soils were sampled one meter apart using a serpentine design. Samples were analyzed for soil saturation percentage, total kjeldahl nitrogen, pH, and gravimetric water content. This sampling occurred in fall 1991. This sampling is complete.
