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.

but the conviction that what we are doing makes sense, no matter how things
turn out." -- Vaclav Havel, former President of the Czech Republic
