Title:	Surface soil analyses from a range of mesquite sites at Jornada Basin LTER, 1986
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data package contains data from a series of analyses of surface soils in mesquite habitats during the early years of Jornada Basin LTER (LTER-I and II). The objective of the study was to determine whether there have been changes in the structure and function of the surface (0-20cm) soil system, the zone most affected by litter decomposition, associated with the rapid movement of mesquite (Prosopsis glandulosa) from historical habitats (arroyo and playa fringe) into recent habitats (grassland and dunes). The mesquite soils were sampled at 4 habitats (playa, coppice dune, arroyo, and grassland) in October 1986, with subsamples analyzed and incubated in the laboratory thereafter. This data set contains analyses for gravimetric soil moisture, pH, phosphate, total Kjeldahl nitrogen, total phosphorus, NO3-N nitrogen mineralization, total inorganic nitrogen, NH4 nitrogen mineralization, organic carbon, inorganic carbon, total roots, tap roots, intermediate roots, and fine roots. This data set is complete.

Methods and protocols used in the collection of this data package

Description:

The objective of this study was to determine whether there have been changes in the structure and function of the surface (0-20cm) soil system, the zone most affected by litter decomposition, which is associated with the rapid movement of Mesquite (Prosopsis glandulosa) from historical habitats (arroyo and playa fringe) into recent habitats (grassland and dunes). Four sites were established at the Jornada Basin in 1986. To compare across habitats, mesquite soil was sampled at playa, coppice dune, arroyo/wash, and grassland sites.

The soils were sampled in October 1986. At each habitat type location (playa, arroyo, grassland and dune) soil samples were collected from the mid canopy beneath six mesquite plants at two depths (0-10 cm and 10-20 cm), using a bucket auger soil corer (7.5 cm diameter, 10 cm depth). The samples were placed in plastic bags, stored in a portable cooler, and then transported to the laboratories. These samples were later divided into subsamples for root mass, soil moisture, and soil chemical analyses.

The gravimetric soil water content of the soil samples was determined 2-4 days after soil sample collection. Samples used for texture, pH, total organic C, total N, and total P analyses were air dried in a glasshouse, ground to break up clay and caliche aggregates, and passed through a 2-mm mesh sieve. N mineralization and inorganic N analyses were made on field-moist soil. Total C was determined by dry combustion following pretreatment with acid to remove carbonates (Nelson and Sommers 1982). Inorganic C was determined by gravimetric loss of CO2 (U.S. Salinity Laboratory Staff 1954). Particle size distribution was determined by hydrometer method following pretreatment in the disperant sodium hexametaphosphate (Gee and Bauder 1986). Total N and P were determined by Kjeldahl digestion block technique (Bremmer and Mulvaney 1982). Soil NH4 and NO3 were extracted in a 2 N KCl solution and analyzed using an automated salicylate procedure (Technicon Industrial Method No. 329-74 W/N). Available P was analyzed as NaHCO3 extractable PO4-P (Olsen and Sommers 1982). The N mineralization potential was estimated using a batch incubation procedure on freshly collected soil as described by Fisher et al. (1987). Two sets of 25-g soil subsamples were incubated at 29C for 4 weeks. The moisture content was adjusted to 0.1 g g-1 (field capacity) at weekly intervals. The soils were extracted with 2 N KCl (Keeney and Nelson 1982) and NH4+ and NO3 were determined as above. Net N mineralization was calculated as the net change in N occurring from the beginning to the end of the incubation period. This study was completed in October 1986.
