Aeration during transport (was Re: [compost_tea] Re: back pack sprayers to use for compost teas?)

We aerate 2 of our tea tanks on the truck with a 12-volt 3.5 cfm
diaphram compressor that was purchased on eBay for $12.50. The
manufacturer of this compressor is GAST. Testing that Elaine has
done, shows 6 hours without oxygen - you're in trouble. Good luck.

little extreme to me. I would figure the level of anaerobic activity
might still be OK though. I haven't tested the transportation
limits. However, you can do a couple of things when transporting for
longer periods: 10 - 24 hours. I wouldn't use tea more than 24 hours
old.

estimation with the tea sitting in the bucket. He hasn't reported
any problems and raves about how much using the tea has improved his
turf. He has applied 4 times in six months to a lawn he was going to
replace. He (this is anecdotal) has stated that he got sick of
mowing his lawn over the summer because it was growing so fast and
was becomming very lush. No inputs other than tea. He applies with
one of those lawn sprayers that fit on the end of a hose. He is on
well water. Water tests low salts, no nitrate contanimation. We
didn't test for metals but he runs the water through a filter that is
supposed to catch some harmful metals.
