excuse my ignorance, I havn't fully researched geotea or compost tea, but from what i've read the tea needs a "fermentation" period for the microbes to spread and then theres the chlorine issue. One source I read said the rate for compost tea was around 150gal/.5acre. thats a ton of materail to apply on a commercial scale or even residential. The tank in the truck looks like a 250gal one, which wouldn't last long at all. I'm all for greener ways of doing things, but this seems like it would be a huge inconvenience.
