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 ...

Managing soil pH is a crucial but often overlooked aspect of soil health and crop productivity, says Marla Riekman, a land ...

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 ...

A new study reveals that implementing enhanced weathering (EW), the practice of adding crushed basalt to soils, with U.S. agriculture could remove between 160 and 300 million metric tons of carbon ...

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 ...

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 ...
