Abstract

This dataset contains biogeochemical measurements collected from the Jornada Experimental Range dryland soils during the 2022 growing season (mid-September). A KMZ file is provided to visualize sampling locations and site characteristics. Soil cores (0-10 cm) were collected from three desert landforms with varying parent materials and two microhabitats (under-plant and interspace). Samples from the cores were reacted with citrate, oxalate, and malate (10 –10,000 µM). The extracts were analyzed for PO43- concentrations via the malachite green colorimetric method, total P and cations (Ca, K, Mg, Fe, and Mn) by hydraulic press/x-ray fluorescence (XRF), dissolved cations (Ca, K, Mg, Fe, and Mn), and P by inductively coupled plasma–optical emission spectroscopy (ICP-OES), and targeted organic acids by gas chromatography-mass spectrometry (GC-MS). These datasets support analyses for determining threshold concentration range of organic acids to mobilize phosphorus across parent material/landforms/vegetation in the Chihuahuan Desert soils.
