Had six holes last year. Wanted to reuse soil. Can I? Has anyone tried it? What do I need to add?

Thanks in advance

I beleive a good soil test will provide the Info you need either local universitys or aglabs will work fine.

Used city water (hard/chlorine). Along with Chem ferts.(Maxsea) It will be 6 months with nothing in soil, but with no rain able to leach soil inside the greenhouse, will soil get/still have salt build up from previous use? Was thinking of leaching soil with garden hose but wouldn't chlorine hurt/kill microbes breaking down soil? I turned up soil and added some compost this weekend. Again holes won't get used again til May. But don't want to waste season and run into problems because of old soil. Then again don't want to replace soil for no reason if not needed.

This is what I do with great results. Just don't add any liming agents for 3-4 runs. If you do it every run your ph can get out of whack.

I re use my soils all the time, at the end of harvest I load it to an old drum pile in some earth worms and leave it for a few months, the earthworms eat the roots hopefully, then a month from use I pile in sheep/goat or chicken shit, in an attempt to give it some nutes ...easy and tight fisted ...lol
