Re: [compost_tea] Re: Chlorinated water



Data is needed, always as she says!
 
Why couldn't a simple test be done with some healthy soil that is tested before and after chlorinated tap water was used to 'water' the soil? Assays could be taken to verify the microbial life that was present and then possibly altered by the chlorine.
 
I too have wondered what was happening to all those happy little critters in the freshly inoculated soil when I turned on the water sprinkler.
 
Couldn't you do this in  your spare time Doctor Elaine?....8~)

OUCH!!!

 

The $1200 DEchlorinating filter insures tea and makeup water are chlorine free, an important part of commercial tea production.  2 million gallons at 0.0006 cents a gallon is a viable solution.

 

We have continued to test the conditions here over the past 4 years. We collect water in a grid pattern used to measure the distribution uniformity of the irrigation systems. Random samples from fine spray patterns (Toro 870 series and Rainbird 1800?s at ½-1 GPM on 10-15 foot patterns) captured in collection cups spaced every 10 feet continue to show high levels of chlorine. It seems with sustainable practices the chlorine does not hamper micorrhyzae and the soil food web is improving. I can?t help but wonder if there wouldn?t be even better results by irrigating with chorine free water. All tea concentrations are applied chlorine free.

 

At home I have always used a 16/1 proportioner with chlorinated tap water. The results have been good and even great. Perhaps the short contact time, a matter of seconds, is not sufficient to affect the biology seriously. Arboriculture standards require contact time in excess of 90 seconds to insure disinfection of soil tools. I just don?t believe dissipation of chlorine is necessarily ?apparent?.

 

More testing is needed. It would seem to be good science for a tea brewer to test their brew water.

 

BTW my tomatoes and vegetables seem (no science) far healthier this year without chlorinated water.

<<<At the levels found in our water(2PPM), there is no dissapation of
chlorine using a lawn sprinkler>>

 

 

Well, if you are promoting and selling 1200 dollar(!!!) chlorinators and your competition turns out to be a simple 10 dollar lawn sprinkler, you might think that! :)
