Abstract
Pedostructure Concept: A New Paradigm for Quantifying Soil Structural Characteristics
Highlights
Soil structure is an important soil property that influences most soil processes
Since soil particles differ in shape, size, and orientation, and can be variously associated and interlinked, their mass can form complex and irregular patterns that are difficult to characterize in exact geometric terms
Mohtar RH [4] further explained that, under the pedostructure concept, the soil medium organization is represented by two nested Representative Structural Volumes (RSVs)-a RSV of the soil horizon and that of the soil fabric, namely, the pedostructure
Summary
Soil structure is an important soil property that influences most soil processes. It is often affected by farm operations such as tillage, seedbed preparation, mulching etc., which are usually carried out to enhance air, water, and nutrient mobility, with the aim of creating favorable conditions for crop growth and yield production. Defined soil structure as the arrangement and organization of the particles in the soil, making reference to it as the internal configuration of the soil matrix. There are no truly universally applicable ways to measure soil structure, several methods are being used to characterize soil structure by measuring certain soil parameters that depend on structure [2,3] Noted that these soil parameters (bulk density, total porosity, penetration resistance etc.) correlate well with soil structure, and as such, they are used as indices of soil structure. These methods describe soil properties independently from their aggregated organization and hydro-structural dynamics [4].
