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 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 ...
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."
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
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.
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 fertility is a complex process that involves the constant cycling of nutrients between organic and inorganic forms. As plant material and animal wastes are decomposed by micro-organisms, they release inorganic nutrients to the soil solution, a process referred to as mineralization. Those nutrients may then undergo further transformations ...
[11] [12] Soil degradation is a gradual process involving the natural and anthropogenic processes that result in the physical loss (erosion) and reduction in soil quality. [7] The recognition of anthropogenic effects on soil degradation has influenced discourse of urban soil management, and formulation of policies by regional organizations. [13]
