Why usually soil is brown in color???
Answers
Answer:
Next time you’re out for a stroll, enjoying a pleasant evening alone, don’t just stop to smell the roses… bend down and check out the dirt. In most areas of the world, that soil tumbling between your fingers will be a certain shade of brown.
This is something that we accept as the natural order of things – the sky is blue, the sun is yellow and soil is brown… but there has to be a good explanation for this universal color choice, right? So why does soil almost invariably look brown?

Short Answer: In fact, not all soil looks brown, but the majority does because of the carbon left behind by microbes.
The Science of Soil
Most people take dirt for granted, or even hate it, particularly when it gets on our clothes or tracked into our houses. However, few people stop to think about what dirty really is. It isn’t one particular thing, however, and is usually a mixture of clays, sand, rocks and organic matter. The most important part of that equation, at least in terms of soil color, is the organic matter.
Depending on where you are in the world, the composition of soil will be particularly unique. In fact, you can identify the source location for most dirt simply by the unique pattern and compositional ratio. Even Sherlock Holmes would be impressed by that sort of clue.
