Abstract:

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.

Description:

Sample collection

A total of 750 soil cores were collected in June 1989 at the 15 NPP study sites. The NPP study has 3 sites in each of 5 vegetation zones (Mesquite, Grassland, Playa, Creosotebush, and Tarbush), with the three sites representing a range in biomass (sites with low, medium, and high biomass). All sites are in the Jornada Basin LTER site approximately 40 km NNE of Las Cruces, NM.. At each of the 15 NPP study sites, cores were collected beneath the shrub canopy, and between shrubs at 5 depths (0-10, 10-20, 20-40, 40-60, 60-100 cm), in 5 directions (In buffer zone just outside NPP plots North, South, East, West, and Center of NPP plot) Samples were analyzed for pH, CaCO3, NaHCO3-extractable P, KCl-extractable NH4 and NO3, total kjeldahl N, Saturation extract cations, and DTPA-extractable micronutrients. Percent organic carbon was sampled at all directions only at the three grassland sites and only at 0-10cm and 10-20cm depth; one site per vegetation type was sampled at all depths for CU (center-under) location only.

Nutrient and chemical analyses

Soil samples were air-dryed in a glasshouse and ground to pass a 2-mm seive. Total N (and TP) was digested by Kjeldahl digestion block techniques (Bremner and Mulvaney, 1982). Digest NH4-N was analysed using an automated salicylate procedure (Technicon Industrial Method No. 329-74W/B).

Inorganic N (NH4-N and NO3 + NO2-N) was extracted with 2M KCl (Keeney and Nelson, 1982). Ammonium-N in the extracts was analyzed colorimetrically (indophenol blue) in an automated procedure (Technicon Industrial Method No. 154-71) and NO3 + NO2-N was measured by an automated Cd reduction colorimetric procedure (Technicon Industrial Method No. 100- 70W/).

Available P was analyzed as NaHCO3-extractable (PO4) P (Olsen and Sommers, 1982).

Percent H2O was determined using the gravimetric method (wt water/wt dry soil).

Soluble cations (K, Na, Ca, Mg) were extracted using saturation extract methods (Rhoades 1982, Richards 1954), and analyzed as following: EC read on Yellow Springs Instruments (YSI) model 32 conductance meter Na, Ca, Mg read on Perkin Elmer ICP/6500 (inductively coupled plasma) K read on Perkin Elmer Model 5000 Atomic Absorption Spectrophotometer using emission mode, acetylene flame

DTPA extractable micronutrients (Zn, Mn, Cu,. and Fe) were extracted using DTPA extraction method (Lindsay and Norvell, 1978), and analyzed using inductively coupled plasma atomic emmission spectrophotometry.

Organic C was determined using a modified Mebius method (J.C. Yeomans and J.M. Bremner, 1988).

Abstract:

The Jornada Basin Long-Term Ecological Research (LTER) program is part of a national network of long-term ecological research sites funded by the US National Science Foundation (NSF). The Jornada LTER program has been continuously funded since 1982 to develop general principles governing changes between grassland and shrubland ecosystems based on long-term data collected in the Chihuahuan Desert. We translate our findings to dryland ecosystems around the world, and forecast the dynamics of future ecosystem states in response to changing climate and land use.

Funding:

At the time of this study, JRN LTER was funded by the National Science Foundation under award DEB 8811160.
