Abstract:

Soil respiration, a critical component of the global carbon cycle, is highly sensitive to warming. Agricultural soils, including abandoned croplands, are large sources of carbon dioxide (CO2) to the atmosphere. However, the responses of soil respiration and its components to warming from abandoned croplands at a large scale. Here, we report the warming responses of soil respiration and its components from abandoned croplands spanning a large range in latitude (22.3 to 46.6°N) and elevation (2 to 3734 m) across China from three-year (2019 to 2021) in situ warming experiments. This dataset is a collation of soil respiration, heterotrophic respiration, and autotrophic respiration and their temperature sensitivity along with information on microclimates (e.g., soil temperature), plant biomasses, soil carbon components (e.g., SOC) and quality under climate warming.

Methods and Protocols

Methods and protocols used in the collection of this data package
Description:

Warming experiments were conducted at twelve sites across China’s abandoned croplands spanning a wide range in latitude (22.33 to 46.58°N), elevation (2 to 3734 m), and mean annual temperature (-0.9 to 22.3°C). The open-top chambers were deployed to simulate climate warming.

Description:

Soil respiration was measured using a shallow PVC collar (5 cm) inserted 2−3 cm into the soil. Heterotrophic respiration was measured using a deep PVC collar (70 cm) inserted 67−68 cm into the soil to exclude roots inside the collar. The difference between soil respiration and heterotrophic respiration was calculated as autotrophic respiration. CO2 concentrations were determined with a gas chromatograph and CO2 fluxes were calculated from the concentration change within the chamber headspace over time. Cumulative CO2 emissions over the sampling period were calculated by linear interpolation between two gas sampling campaigns.

Description:

Plant aboveground-biomass was clipped at the soil surface using a quadrant method. Soil cores (5 cm in diameter and 30 cm in depth) were taken to measure belowground-biomass. Plant net primary productivity in aboveground- and belowground-biomass was calculated by multiplying carbon concentration by the respective dry plant biomass. The difference between net primary productivity and cumulative C emissions by heterotrophic respiration was estimated as net ecosystem productivity.

Description:

Surface soils (0–10 cm) were collected using a 5 cm diameter soil auger. The soil cores were oven-dried at 105°C and weighed for bulk density and soil moisture. Soil organic carbon was determined after removal of inorganic carbon with 2 M HCl. Soil microbial biomass carbon was measured using the fumigation extraction after the extraction with 0.5 M K2SO4. Soil dissolved organic carbon was measured with nonfumigated extracts.

Description:

The temperature sensitivity (Q10) of soil respiration and its components at each site during the three-year experiments were fitted with soil temperature using the following equations (R = BekT and Q10 = e10k), where R is the rate of soil respiration, heterotrophic respiration, and autotrophic respiration (mg m-2 h-1), T is soil temperature (°C) at the depth of 5 cm, B denotes basal respiration rate when T is 0°C, and k is a parameter defining the temperature dependence of respiration. Parameter B in equation fitted between soil heterotrophic respiration and temperature was used to represent soil carbon quality. The activation energy was obtained by fitting the rate of heterotrophic respiration to the Arrhenius Equation.
