Is this a crazy, pointless idea?

Here is a picture of the raised bed I grow carrots in:



I think I've sown the carrots too deep but that's irrevelant. There appears to be a ton of all sorts of things growing in here, including the never ending horsetail.

After the growing season, would it be feasible to dig the entire thing out to a depth of 1.5 meters (which I heard is the depth horsetail gets down to) and dump a load of fresh compost in it?

The cost/manpower isn't the issue for me here - but if in a few years time I would end up in the same situation I am now due to relentless weed germination carried onto the bed via wind I feel it would be pretty pointless.

Mare's (horse) tail can go down much deeper than that. The roots have been found in coal mines..

I'm really not sure about this idea. I suspect it's Chinese whispers because fossil horsetails are sometimes found in coal. Certainly googling doesn't seem to throw up any depths beyond 2 or 3 metres...

Ever heard of open cast mining? 

Okay, scratch that idea. Thanks everybody
