driverssoil

Driversoil is a term used in soil science to describe soils whose physical, chemical, and biological properties are dominated by a set of driving factors or drivers such as moisture regime, temperature, aeration, and biological activity. In this framework, soil state is considered dynamic, with properties changing in response to external and internal drivers rather than remaining static.

Origin and usage: The concept has appeared in theoretical models and experimental studies since the early 2010s, particularly in discussions of transient soils, wetting-drying cycles, and biotic interactions. It is not a formal classification in standard soil taxonomies and is used mainly to emphasize dynamic responses over time.

Characteristics: Driversoil soils exhibit heightened sensitivity to environmental changes, showing rapid shifts in bulk density, porosity, water-holding capacity, mineral weathering rates, enzyme activity, and microbial community structure. The degree of responsiveness depends on texture, structure, organic matter content, and rooting patterns.

Mechanisms: The drivers include hydrological changes (precipitation, evapotranspiration), temperature fluctuations, redox conditions in poorly drained soils, mechanical disturbance, and plant root influx. These drivers alter pore networks, nutrient dynamics, and microbial processes, leading to cascading effects on soil function.

Applications and significance: The concept helps in understanding transient soil behavior in managed ecosystems, agriculture, and climate-active landscapes. It informs modeling of soil carbon dynamics, erosion potential, and nutrient availability under changing climate and land-use.

Limitations: Driver soil is not a universally adopted taxonomy and a one-size-fits-all definition does not exist. It emphasizes dynamics rather than steady-state conditions and should be used alongside conventional soil descriptions.
