Reusing potting soil

I was wondering what's everyones take on reusing soil? When I was dumping my pots I saw that there was a lot of soil on the outside that had no roots in it. Can I mix half old and half new soil in the pot and use hygrozyme to kill the dead left over roots?

From a theoretical point of view, I recon it should be ok - soil is soil, and any remaining nutrients should get used up pretty quickly (just to be safe, i'd probably flush it with water first). But I speak from theoretical knowledge, not experience.
