Question

Quizplus · Accepted Answer

Color of soil reflects its composition and chemical makeup, which can include factors such as the presence of iron oxide, organic matter, and minerals. The color can thus indicate important soil properties such as fertility and drainage. While dark soils often do have high organic content, this is not always the case, and soil color can be influenced by a variety of factors beyond just organic matter content. There are standard methods for describing soil colors, such as the Munsell Soil Color Chart. Soil color is not solely used to determine moisture content, as soil texture and structure also play important roles in water retention. While there are a limited number of basic hues that soils can exhibit (e.g. red, yellow, brown, gray), the precise shade and intensity of these colors can provide valuable information about the soil's properties.
