Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality relates to soil functions. Unlike water ...
Soil represents one of the largest C sinks on Earth and is significant in the global carbon cycle and, therefore, for climate change mitigation. [6] Therefore, SOM/SOC dynamics and the capacity of soils to provide the ecosystem service of carbon sequestration through SOM management have received considerable attention.
Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.
The term natural cycling appears in a 1968 paper on the transportation of leaf litter and its chemical elements for consideration in fisheries management: "Fluvial transport of tree litter from drainage basins is a factor in natural cycling of chemical elements and in the degradation of the land."
Soil degradation means that soil quality has diminished, which causes ecosystem functions to decline. [1] One third of the globe's land has degraded soil; [1] especially the tropics and subtropics with around 500 million hectares. [1] Soil degradation occurs due to physical, chemical, and biological forces. [5] These forces can be natural and ...
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
Role in Soil Fertility: HSs are the primary components of soil organic matter. They are important for soil quality and fertility. Impact on Aquatic Systems: In aquatic ecosystem, HSs affect pH, alkalinity, and the chemical cycling of elements. Though Humic acid contributes to water pollution by altering colour and forming harmful by-products ...
The phrase "soil health" has largely replaced the older "soil quality". The primary difference between the two expressions is that soil quality was focused on individual traits within a functional group, as in "quality of soil for maize production" or "quality of soil for roadbed preparation" and so on.
