Title:	Effects of Habitat Type on Nitrogen Availability in Soils Under and in Proximity to Mesquite Plants on the Jornada Basin LTER, 1986
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Four mesquite ecosystems were studied: playa, coppice dune, arroyo (or wash), and grassland. An ecosystem dominated by the non-legume, Larrea tridentata, and lacking mesquite was included as a reference. At four shrubs on each site, samples were taken from two depths (0-15cm, 15-30cm) and three canopy positions: base, mid-canopy, canopy edge. An interzone area was also sampled at both depths. The soils were analyzed for Total Kjeldahl Nitrogen (TKN), inorganic N-- nitrate-N, and ammonium-N. This study was conducted in 1986 and is complete.

Description:

Sampling took place on October 1, 1986. Soil samples were taken (augered) from three canopy positions (base, mid-canopy, and outer edge-of-canopy) and one interzone position (unvegetated area one radius distance from shrub edge). The interzone distance was less when tree spacing was closer. Two soil depths, 0-15cm and 15-30cm, were sampled at each position. Soil samples were air-dryed in a glasshouse and ground to pass a 2-mm sieve. Total N 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/).
