Since physical and chemical erosion yield comparable carbon fluxes, studying both together is essential to avoid biases in erosion-driven carbon flux estimates.

All plants require 17 elements to complete their life cycle, and an additional four elements have been identified as essential for some plants (Havlin et al. 2005). With the exception of C, H, and ...

Weathering and erosion slowly chisel ... When the glacier begins to melt, it deposits its cargo of soil and rock, transporting the rocky debris toward the sea. Every year, rivers deposit millions ...

Table 1: Common salts found in saline soils. Soils are naturally composed of inorganic minerals, including primary minerals (e.g., quartz, micas, or feldspars) and their weathering products, including ...

I recently got a question from a reader about where to get good soil and compost. Part of her request was for “organic” soil ...

Chemical reactions that control soil formation and weathering reactions occur almost exclusively in liquid water (Lindsay 1979). Physically, water is the diffusive medium that mediates the ...

If you scoop up a handful of dry soil, the basic dirt that you feel in your hand is actually very small pieces of weathered ...

Soil creep is a very slow movement, occurring on very gentle slopes because of the way soil particles repeatedly expand and contract in wet and dry periods. When wet, soil particles increase in ...

When European-American settlers first began ploughing in Iowa, they found the weather and local geology had combined this organic mulch with sand and silt to form a nutrient-rich type of soil ...
