Representing air as imaginary water: Analysis of soil water and soil aeration corequisites for plant growth
Abstract Plant‐available water and adequate soil aeration are two fundamental requirements for successful plant growth. These prerequisites have generally been assessed independently in relation to plant growth, with limited focus on their complementary and competing behavior in a soil–water…

A field calibration method that improves soil heat flux accuracy
Abstract Soil heat flux plates (SHFPs) are widely used to measure soil heat flux (Gs). Gs is often underestimated by SHFPs (Gp). Although calibration methods are used, they are not always effective. The objective of this study is to evaluate the effectiveness of a field calibration method applied…

Gaia: Complex systems prediction for time to adapt to climate shocks
Abstract Earth's climate has undergone significant fluctuations in the geologic past, while the sun's radiation continues to increase, yet has always returned to conditions highly favorable to life. Thus, the biosphere overall appears able to cancel effects of external trends as well as provide…

Modeling compaction effects on soil water retention across the full moisture range: Calibration and validation
Abstract Soil compaction leads to an increase in bulk density (ρb) and results in a shift in pore‐size distribution toward smaller pores. These changes alter the soil hydraulic properties (SHPs), that is, the water retention curve and the hydraulic conductivity curve. Most existing models that…

Re‐evaluation of the centrifuge method for describing the unsaturated hydraulic functions of porous rock and till soil samples
Abstract The determination of hydraulic characteristics as a function of the pressure head is laborious and data ranges are restricted. Indirect methods to estimate K(h) are introducing additional uncertainty and the method‐dependent restricted data ranges that can hamper a bimodal curve fitting…

Joint multiscale dynamics in soil–vegetation–atmosphere systems: Multifractal cross‐correlation analysis of arid and semiarid rangelands
Abstract Understanding the dynamics of the soil–vegetation–atmosphere (SVA) system, particularly in arid and semiarid regions, remains challenging due to its intricate and interdependent nature. This system creates problems for rangeland administration, such as insurance and risk management. This…

Identifying preferential flow from soil moisture time series: Review of methodologies
Abstract Identifying and quantifying preferential flow (PF) through soil—the rapid movement of water through spatially distinct pathways in the subsurface—is vital to understanding how the hydrologic cycle responds to climate, land cover, and anthropogenic changes. In recent decades, methods have…

A formulation for assessing the risk of anthropogenic drought based on drought characteristics and socioeconomic and physical factors
Abstract Determining the contribution of human activities to drought occurrence or aggravation of drought is an essential issue in drought risk management. Drought begins under the influence of meteorological processes and propagates to hydrological drought, which human activities affect. In this…

Extending the measurement range of the simplified evaporation method using humidity sensors
Abstract The simplified evaporation method (SEM) is widely used to determine soil hydraulic properties (SHP), specifically the water retention curve (WRC) and hydraulic conductivity curve (HCC), but its application is limited to the suction range measurable by tensiometers. While advances in…

Large‐scale photovoltaic farms significantly change the vegetation diversity and biomass through influencing soil moisture and physiochemical properties
Abstract Large‐scale deployment of photovoltaic (PV) farms alters the surrounding microclimate. Microclimate changes and engineering buildings have caused significant changes in vegetation, although the mechanisms behind change have yet to be thoroughly investigated. The goal of this study was to…

Monitoring dynamic water content, bulk density, and heat and water fluxes in the critical zone with thermo‐time domain reflectometry sensors
Abstract A thermo‐time domain reflectometry (thermo‐TDR) sensor combines a heat‐pulse sensor with a TDR waveguide to simultaneously measure coupled processes of water, heat, and solute transfer. The sensor can provide repeated in situ measurements of several soil state properties (temperature, soil…

Statistical considerations in the analysis of minirhizotron data and a review of current practice in agronomic research
Abstract A growing body of agronomic research seeks to understand the drivers of plant‐ and field‐scale patterns of crop root system distribution, and how root system distribution in turn affects crop performance. Minirhizotrons play an important role in this effort due to the unique opportunities…

Microbial O2 consumption as a function of pore structure in soils of sorghum, switchgrass, and prairie vegetation systems
Abstract Microscale O2 availability in soil, a main factor influencing microbial processing of soil carbon and nitrogen, is a function of O2 diffusion and microbial O2 consumption. While O2 diffusivity is widely studied, it is difficult to quantify the rate of microbial O2 consumption (MO). In this…

Insights into freeze–thaw and infiltration in seasonally frozen soils from field observations
Abstract Snowmelt infiltration into frozen soils in seasonally frozen landscapes is a critically important hydrological process, with consequences for agriculture, water resources, and flooding. The partitioning of snowmelt between infiltration and runoff in any given location and in any given year…

Review of conceptual and empirical approaches to characterize infiltration
Abstract Infiltration regulates the movement and storage of water at the soil–atmosphere interface and is, therefore, a key component of many related physical and biogeochemical processes. Numerous studies have examined infiltration over the past two centuries. These efforts have resulted in the…

A novel design for continuous measurement of CO2 from deep remineralization of petrogenic organic carbon
Abstract The oxidation of petrogenic organic carbon contributes a large CO2 flux to the atmosphere, regulating the geological carbon cycle. While few in situ fluxes have been measured in near‐surface sedimentary rocks, deep fracture‐controlled metamorphic terranes remain unexplored. Here, we…
