Kill the weed ones to reuse last year's topsoil.

How much topsoil are we talkin' here?

Now that I live in an apartment with a deck, two buckets worth about the
size I can just barely loop my arms around. Several times less than I
used when I had a place with a back yard. Reusing the dirt becomes
something fun to do to have keep some planting skills from
dissappearing.

Even with that small amount of dirt, earthworms and mycorrhiza will help
produce better results. Unless you suspect that you have Fusarium,
Verticillium wilt, or some other soil disease, I wouldn't sterilize it.
I sterilize my potting mix because I'm germinating seeds in it, and have
had trays wiped out, in the past, by damping off.
