[compost_tea] Re: [SANET-MG] Regulation of compost teas



-
Lawrence - We use an all fruit, vegatable, minerals and wood based 
compost, use a rather light load of nutrients with plenty of 
aeration, we get and accept what is good to excellent numbers of 
microbes - both bacteria and fungi.  we do not try for extremly high 
numbers with heavy nutrients because we want to be well on the safe 
side of plenty of O2.  We do use an Oxygen meter because we are 
developing the brewer and want to know how it acts under many 
conditions. With the recipes furnished the brewer always runs in the 
high 7 to 10 range of O2 so there is no hazard from the e-coli and 
salmonella and such.  Never anaerobic. 

Still a good idea to test but not required often if you stay near the 
standard proceedures.  It does make Compost tea very inexpensive and 
has proven highly effective.  We apply nearly 500 gallons a day on 
customers landscapes and gardens. That is going to be much more next 
year, all produced by the " little brewer that fits in a duffle bag" 
that Jeff talked about  Bob
