ABSTRACT:

This data contains major anion and cation analyses for shallow groundwater samples and irrigation water samples, taken following 1 irrigation event in July 2022 and 1 irrigation event in July 2024. Data is also plotted on Piper Diagrams for visualization as water chemistry evolves following an irrigation event. Preliminary results show that water becomes more Na Cl rich, from Ca-Mg-CaCO3. The irrigation water applied is much more dilute than any groundwater samples, suggesting that the change in chemistry comes from processes happening within the vadose zone as water percolates following irrigation - dissolving existing soluble salts (NaCl) and precipitating less soluble salts (CaCO3).

ABSTRACT:

This dataset contains data from two soil sensor monitoring arrays installed at Ivey Pecan Orchard. There are two sites installed in contrasting soil textures, Pecan_Fine and Pecan_Coarse. At each of these two sites, there are the following sensors: barometric pressure from Apogee SB-100 sensors, VWC, EC, T from Campbell CS-650 sensors, O2 and T from Apogee SO-110 sensors, at 30cm and 60cm, CO2 concentration from Vaisala GMP343 (at 30cm) and Vaisala GM251 (at 60cm), and CO2 efflux at the soil-air interface from Eosense eosFD chambers. At Pecan_Coarse there is also a differential pressure sensor from Dwyer Digimag DM-003 Differential Pressure Gauge.

ABSTRACT:

This dataset contains data from the Ivey Pecan Orchard soil monitoring sensor array. These sensors are installed at two sites with contrasting soil textures - Pecan_Fine and Pecan_Coarse. At each of these sites, there are the following sensors: VWC, EC, T, O2, CO2 at 30cm and 60cm depths, and CO2 efflux at the soil-air interface. At Pecan_Coarse, there is also a differential pressure sensor measuring the difference between ambient pressure and soil pressure, in order to better capture changes in pressure. These changes in pressure may contribute to changes in CO2 efflux as advection dominates over diffusive CO2 transport.

ABSTRACT:

This dataset covers soil inorganic carbon (SIC), radiocarbon dates (14C) for a pecan orchard near Tornillo, TX, an alfalfa field formerly within El Paso/Socorro, TX, and a natural site near Fabens, TX. This data also includes optically stimulated luminescence dates (OSL) for the pecan orchard. These dates and SIC contents are then used to calculate pedogenic carbonate accumulation rates. Additionally, data is provided on soil amendments at the pecan orchard to understand the potential contributors of pedogenic carbonate.
