Prairie soils developed many yards thick, whereas forest soils tend to be much thinner.
Prairie grasses grow very deep roots, then when buffalo came along and ate it or trampled it, the plant sheds those roots to match the above-ground growth. The green leaves regrow every year, or several times a year according to this pruning. The shed roots and any trampled or dead leaves become compost which improves and thickens the soil.
Forests do not have such fast soil development, because their only source of new compost is generally from leaves as they fall, or occasional trees when they fall. The accumulation of biomass is much slower. Evergreens do not shed yearly leaves like deciduous trees, so they develop soil slowest. Also, evergreens tend to grow acid soils compared to prairies.
Forest soils differ from prairie soils first by having an "O horizon". An O horizon is a layer in the soil, normally found at the top, which contains Organic matter and other decaying material. A forest soil also tends to have larger macropores due to the larger amount of vegetation that has roots growing there. A forest soil has a lower C:N (carbon-nitrogen) ratio, and is normally more moist than the prairie soil.

What is the difference between forest and prairie soils?
Forest soils tend to be rich in organic matter, have higher acidity, and more microbial activity due to the decomposition of leaf litter and organic debris from trees. Prairie soils, on the other hand, are often characterized by a thicker topsoil layer, higher pH levels, and lower organic matter content, as grasses do not contribute as much organic material as trees.
What soil is formed under big vegetation?
You will have to define big vegetation before anyone can answer this question.There are big differences between soils that stem from the type of vegetation that grows on them. Prairie soils are much different than forest soils, for example.
Why do bones generally preserve better in prairie type soils than in forest type soils?
Prairie type soils are usually drier and have lower acidity levels compared to forest soils. These conditions are better for preserving bones as they hinder decomposition and minimize the presence of organisms that can break down bone tissue. Additionally, the lack of dense vegetation in prairie soils makes it easier for bones to remain undisturbed over time.
Why is the soil profile in a rain forest different from in a desert?
The soil profile is different because the desert soil profile has contained a little organic mater also are thinner than soils in wetter climates.Prairie soils have thick, dark A horizons because the grasses that grow there contribute lots of organic matter. Temperate forest soils have thinner A horizons than prairie soils do.
What can prairie soils often be identified by?
their color
What type of soil is in the interior plains?
The soil in the Interior Plains of North America is typically fertile and a mix of prairie soils and chernozem soils. Prairie soils are rich in organic matter and nutrients, while chernozem soils are dark, fertile soils found in grassland regions.

How do the soils of the Atlantic coast differ from the soils of the Gulf of Mexico coast plain?
they differ because the gulfs soil is richer than the Atlantic's.
Which vegetation region of the US has themost fertile soils?
The tall grass prairie region has the most fertile soils. As you move westward, the tall grass prairie starts somewhere in Illinois, and includes Iowa, southern Minnesota, the eastern Dakotas, eastern Nebraska, eastern Kansas, and northern Missouri. It gradually becomes short grass prairie, which also has quite fertile soils, but not to the same depths as tall grass prairie.
Is the following sentence true or false Prairie soils are no longer among the most fertile soils in the world?
False. Prairie soils, specifically those found in the Midwestern United States, are still considered some of the most fertile soils in the world due to their high organic matter content and nutrient levels. These soils have been the backbone of productive agriculture in the region for many years.
