Abstract:

In this dataset, we report germination and seedling growth of contrasting perennial grass (Bouteloua eriopoda, Sporobolus airoides, and Aristida purpurea) and shrub (Prosopis glandulosa, Atriplex canescens, and Larrea tridentata) functional groups grown on non-winnowed and winnowed soils collected from the Jornada Basin LTER Scrape Site at the Jornada Experimental Range (JER) in southern New Mexico, U.S.A. The soil physical and chemical properties of winnowed and non-winnowed soils were evaluated, and soil water retention curves were obtained for the two soil types. A controlled pot experiment was conducted under the well-watered greenhouse conditions at the University of Arizona campus, Tucson, AZ in 2018 and 2019 to test if topsoil "winnowing" by wind erosion would differentially affect grass and shrub seedling establishment to promote shrub recruitment over that of grass. Data include soil water retention curves, soil chemistry, nutrients, and texture, seedling germination, and seedling growth and biomass. This study is complete and the data are published in the article below.

Description:

Experimental design and soil collection

Soils used in this study were collected from the 'Scrape Site' at the Jornada Experimental Range (JER)/Jornada Basin Long-Term Ecological Research site, New Mexico, USA. The Scrape Site was first cleared of vegetation and the A and B Horizon in 1995 by Brad Musick according to his specifications. Kris Havstad of USDA Jornada Experimental Range may know more details. What is left is a soil crust that is uniformly abrading down through wind erosion. The scraping occurred on a 100 meter radius semi-circle. There are three monitoring stations (East, Middle, West) in the semi-circle of the Scrape Site. The West site is the windward site, the East site is the leeward site, and the middle site is halfway between the other two.

Soil analyses

Collected soils were classified according to the USDA guidelines. The texture was determined by the hydrometer method. Soil pH and electrical conductivity (EC) were measured in 1:1 soil to water suspension (volume to volume; deionized water). Exchangeable cations, including K+, Na+, Ca2+, and Mg2+ were analyzed in ammonium acetate solution buffered to pH 8.5 using an inductively coupled plasma optical emission spectrometry (ICP-OES, iCAP7200, Thermo-Fisher, Freemont, CA, USA). Soil NO3− was extracted with 2 M KCl and analyzed by reduction to nitrite (NO2−) via cadmium reduction. Soil PO43− was extracted using 0.5 M NaHCO3 adjusted to pH 8.5. Both NO3− and PO43− were measured with a continuous flow analyzer (San++, Skalar CFA, Skalar Analytical BV, Breda, the Netherlands). Cation exchange capacity (CEC) was estimated as the sum of exchangeable K+, Na+, Ca2+, and Mg2+. Exchangeable sodium percentage (ESP) was calculated as ESP (%) = (exchangeable Na+/CEC) × 100. Soil total C and total N were measured with a C&N analyzer (LECO TruSpec, LECO Corporation, St. Joseph, MI, USA). Mean values for a given soil variable are based on n = 10 replicates. To generate soil water retention curve for each soil type, air-dried soil samples were sieved through 2 mm mesh and rewetted with deionized water to create a range of water contents (ranging from low [air-dried] to saturated in 0.025 g g−1 intervals; n = 6 per soil water content) per Campbell et al. (2007). Water potentials of these soil samples were then determined with a dewpoint water potential meter (WP4, Decagon, Pullman, WA, USA). Following water potential measurements, soil samples were oven-dried at 105 degrees C for 24 h and weighed to derive gravimetric water contents.

Pot trials

Pot trials were conducted in a greenhouse on the University of Arizona campus in Tucson, AZ, USA. Small plastic pots (8 cm width × 8 cm length × 6 cm height) were filled with either non-winnowed or winnowed soil (n = 10 per species per soil type for a total of 120 pots). Pots had holes on bottoms to allow drainage of excess water. Ten seeds per species were sown ~1 cm below the soil surface in each pot for all species. Soils were brought to field water capacity on the day of sowing and moistened with the same amount of water daily thereafter. Seed germination, defined as cotyledon emergence, was recorded daily. The experiment ceased when zero cotyledon emergence was recorded in all pots for five consecutive days. Two separate trials of the seedling growth experiment were carried out: one in 2018 (04 March – 04 April, 31 days) and the other in 2019 (01 January – 17 March, 76 days). The greenhouse received full sun exposure and contained no supplemental lighting. The daytime temperature maximum was set at 32 degrees C and the nighttime minimum was 24 degrees C, which is a favorable temperature range for the germination and growth of the species in our experiment. During each experimental trial, plants were grown in 26.5 cm tall × 3.15 cm diameter "Cone-tainers" (Stuewe and Sons, Inc., Corvallis, OR, USA). Pots (n = 12 per species per soil type for a total of 144 pots) had a 7.5 cm base layer of mineral wool (to prevent soil from falling through drainage holes) overlain by 14 cm of play sand. The sandy base layer was then topped (upper 5 cm) with either non-winnowed or winnowed soil. Pots were spatially randomized on the greenhouse bench. The pots were brought to field capacity on the day of sowing and kept moist by adding the same amount of water per pot daily thereafter. At the end of the experiment, plant height and number of leaves were recorded. Aboveground material was separated into leaf and stem categories (for shrubs) and soils were gently washed away from roots. Plant materials were oven-dried at 65oC for 48 h and weighed.

Please refer to Niu et al. (2021) for other details regarding materials and methods.

Abstract:

There are numerous investigations into how aeolian processes drive and reinforce ecosystem state changes at the Jornada Basin Long-Term Ecological Research site (JRN LTER). Research activities include aeolian transport monitoring, vegetation removal experiments, and investigations on plant survival and establishment. JRN LTER 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.

Funding:

Aeolian research at JRN LTER is partially funded by the NSF awards "Aeolian Processes: An Overlooked Driver of State Change in Drylands?" under award numbers DEB 1556735 (PI Greg Okin) and DEB 1556587 (PI Steve Archer). JRN LTER is funded by the National Science Foundation under award DEB 2025166.
