Re: [compost_tea] Pressure & critters



Based on looking at teas sprayed out at lower pressures, versus higher pressure, using the same sprayer, there is little effect on the set of organisms up until you get to really high pressures.

Passage through the sprayer pump can do more damage than the pressure the organisms are subject to.  Hitting a leaf surface at high pressure is what kills the critters, not the pressure they deal with in the liquid. 

Based on observation from a number of teas.
