Re: [compost_tea] Re: Holding time for tea



The microbes on the leaf surfaces just IMPROVE the uptake of foliar nutrients.  Uptake is controlled by stomate opening, and opening the stomates depends on CO2 concentration in the atmosphere of the leaf.  Microbes respire, increase CO2 concentration in the leaf surface atmosphere, and speed the stomatees opening, increase the time they stay open.

As weather gets drier, the microbes have less water, they respire less. 

Works pretty well to help plants pump nutrients in when it's appropriate to do so.
