What is this thing on my farm?
I am completely novice to organic farming. However, I am reading books and growing citrus plants using only fertilizers and pesticides made from natural sources like cow dung, vermicompost, neem etc. (No commercial or non-commercial chemical based products). In the last couple of day since watering, I am noticing this thing on the soil. Please see attached. Thanks for advising.

Though I can't say for sure from the photo, this looks like the result of earthworm activity. The worms make channels in the soil that sometimes leave mounds similar to this on the surface. If you dig into the soil with a shovel, do you observe earthworms?
