Soil scientists prepare the maps in the field using pits, core samples, or trenches to examine the soils. They outline the extent of different soils using aerial photography base maps that help identify landscape positions, landforms and vegetation patterns that are …
There are different types of soil, each with its own set of characteristics. Dig down deep into any soil, and you’ll see that it is made of layers, or horizons (O, A, E, B, C, R).

Soils and Climate
Climate has an important role in soil formation. Observing soils and soil profiles can give clues to past climates and weather cycles. Some climates have soils that are not as deep or fertile and require special management for preservation. Soil is an important part of the global carbon cycle.
Each soil type has unique characteris-tics that provide important clues about its history, formation and location of origin, such as color, texture and structure. For example, the color of a soil indicates its history as well as the compounds present in the soil. White or gray soil may contain lime or have been leeched, while black or gray

And there are different soils all over the world from farms to prairies, polar regions to tropical islands, and wetlands to deserts and forests. Soil is very important to all of us. We need healthy soil to live healthy lives. So, be good to your soil! I Heart Soil Coloring Book and ...
their design. Soil maps are created by soil scientists and present information such as: • the slope of the land surface; • soil biological, chemical, and physical properties; and, • potential for water runoff, drainage, or storage. Soil maps are available for public access from the USDA Natural Resource Conservation Service at the Web Soil
