WebClimate. Wetlands can be found in any climate, from the tropics, to the tundra (in summer). As long as soils remain wet, they can have very little precipitation, or a lot. If a lot of plants grow in this area, they die and sink to the bottom of the water. They decompose slowly, and often stay very dark in color (black).
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain siz… pop its fidget toy bigWebSoil-Stiffness category 1 (SC1) Crushed rock and gravel with <15% sand and ≤ 5% fines. SC1 materials provide maximum stability and pipe support for a given density due to the low content of sand and fines.

Cultivations should be kept to a minimum. Reduced tillage is often appropriate, especially where free lime is present, with deeper loosening every 3–4 years and mole draining every 4–7 years to ensure good drainage.
