Answer 1

Also, are you thinking of dirt or soil? A lot of the stuff that plants grow in is brown because it’s full of organic matter not just rocks and minerals. And it’s very location dependent, I am in Australia where a lot of the dirt is red, not just in the outback but where crops are grown too. It’s amazing to see a freshly tilled field of all red furrows!
