RE: [compost_tea] Pressure & critters



Seems to me that they’re getting splatted against things immediately before leaving the sprayer –that’s how the sprayer works.  Pressure builds up in the tank, and then the water hits a fitting at the end of the hose connecter that in turn, makes the spray fan out and maintain pressure.  I can’t imagine how that could be any better than flying through the air for a while and then hitting a plant – even if it were a jet stream, it seems better than what the sprayer nozzle does to them little critters.

 

Maybe I’m thinking about this too much again, I don’t know.

Pressures up to 70 PSI are what you can expect from a pump sprayer.  This is fine for the microbes. The problem is the velocity at which they hit things. That is where you need to be most careful. Splatted microbes are dead ones....Spraying is an art.
