Abstract:

This dataset contains physical soil characteristics, PLFA based microbial community composition, extracellular enzymatic activity, and phosphorus availability in various phosphorus pools (Biologically Based Phosphorus, potassium sulfate, Olsen-P). Soils were collected from two depths (0-2cm, 2-30 cm), four microhabitats (grass, shrub, biocrust, interspace), and four landforms (alluvial flat, alluvial fan remnant, erosional scarplet, fan piedmont – see coordinates) within the Jornada Experimental Range in July 2021 to answer questions about how these variables change across these spatial scales in drylands. This project was a collaboration between researchers at New Mexico State University and The University of Texas at El Paso as part of the Drylands Critical Zone Thematic Cluster within the Critical Zone Network. This dataset is complete.

Abstract:

The Jornada Basin is home to multiple long-term research networks, including the Dryland Critical Zone (CZ) program and the Jornada Basin Long-Term Ecological Research program (JRN LTER). The Dryland CZ is part of a national network of long-term research sites funded by the National Science Foundation (NSF). JRN LTER is part of a national network of long-term ecological research sites funded by NSF. The JRN 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.

Funding:

The Dryland CZ program is funded by the National Science Foundation under award EAR 2012475. The JRN LTER program is funded by the National Science Foundation under award DEB 2025166.
