There are several possible reasons for this. This article will explain:

Here is a whole section on carrots that should help:
I have been cropping my carrots and most of them are fine, but some are coming out of the ground with lots of very thin white creatures on them. Please see the attached photo
They look to be a type of centipede. It is hard to get a good look from this picture. If this is the case, then they are likely predatory. They are probably hunting smaller prey that is harming your carrots.
This collection of articles will offer more information on growing carrots:
The issue: My carrots are 2 weeks from harvest time and developing tiny white spots on a few of the green stems near the root of the carrots with the largest tops. This is my first time growing carrots so I observe everything. Their history: They are growing in a bucket which I've had to tip over twice because it rained. This is how I drained the water so they don't drown. The drained water was clear the first time but had green algae in it the second time. I'm in Texas and they had a rough start but now appear to be thriving. There still appears to be green algae on the surface of the soil. The tops look beautiful.
Does your bucket have any drainage holes? If not, you need to add some. The more the merrier. Spider mite damage is usually stippling on the leaves. Tiny white spots could be powdery mildew developing or even aphids. Neem oil would help in either case. (black swallowtail eggs are like tiny white pearls but they are usually on the leaves.)

There is a possibility that the soil or carrots were infested prior to planting or at planting time. This would make it to where they will treat your containers as "ground".

Interplanting with onions is a really good way to keep away pest insects. The chemicals within the onion are natural pest controls.

rywhere. Small fern like leaves, close to the ground but not foiled. What is it and how do I get rid of it? It has thick tuberous roots which go deep, even for the tiny,just-emerging ones
This is one of a few very similar looking species. The first thing that I would check will be the smell of the root. If it smells like carrots, then you have the wild carrot.
If it smells less like a carrot and more earthy, and there are no purple markings on the stem, then this could be in the same genus as edible parsley. This could include wild parsley.
As well, there are toxic species of hemlock that look like this. Consult your local master gardeners for a more in depth look at your plant in question.
It's one of those that is hard to identify because it has several lookalikes. I looked at RHS gardening's common weeds and it does look similar to herb Robert, but it also looks like Queen Anne's lace and poison hemlock (poison hemlock has purple splotched stems). It also resembles the herb sweet Annie.
I suggest using an herbicide to be sure you get the roots, especially if it's poison hemlock. Since they are thick roots, it may take more than one application.
