Project: Soil nutrient distribution in long-term NPP plots

Project ID: 210398000

The LTER plant biomass plots was sampled in June 1989. A total of 750 soil samples were collected from 5 depths (0-10, 10-20, 20-40, 40-60, 60-100 cm), 2 locations (under and between shrubs), within 5 vegetation zones (Mesquite, Grassland, Playa, Creosotebush, Tarbush), 3 sites per zone (site with low, medium, and high biomass, ranked based on FALL-89 biomass), and 5 directions per site (in buffer zone just outside of NPP plots N, S, E, W, and in the center of NPP plots C). Samples were analyzed for pH, CaCO3, NaHCO3- extractable P, KCl-extractable NH4 and NO3, total kjeldahl N, Saturation extrac cations, and DTPA-extractable micronutrients.
