If you are going to time, trouble and expense to put out compost tea to improve the soil biology the put enough out to get your bugs to the soil!  A mist that dries immediately seems like a waste to me - I want to be able to walk on pasture I just sprayed and get my shoes very wet.  Expect to use 40 to 50 gallons (50/50 Compost Tea to well or lake water) PER ACRE!    I’m not convinced ANY spray nozzle is the way to go.  I want compost tea ON THE SOIL - so a stream or a soil injection system is the ticket.   For foliar applications nozzles are great but for building soil I feel you need a soil drench AND decent rain - soon!

And while we are talking about spray nozzles - if you have any wind at all be prepared to smell like your compost tea.  If you add liquid fish to your tea your animals will love you - your family will not!  ;-))

Do your sprays in the late afternoon, early evening, just before or better yet during a rain so the microbes get a chance to set up shop before the scalding sun begins to cook the pasture.  Remember to send your freshly brewed microbes out with extra molasses added to the tank just before application.  Like a box lunch to help them get a good start.

I feel that at least half the real value in compost teas are to add nutrients (seaweed, fish, humates, sugars, enzymes, catalysts etc.) to the soil to promote the growth of the existing beneficial microbes and fungi.   You can add thousands of species of bacteria and fungi, etc. via the compost tea portion but only some drastically reduced number will actually live and thrive in your soils specific ecosystem.  Your soil type, slope,  average wind speed & direction, rainfall, day & night humidity, etc. will select the microbes and fungi that will thrive in your specific ecosystem.  Most microbes or fungi that can and will grow there are already “in the wind” - that’s how nature designed it.  So don’t make this Compost Tea any more complicated than it has to be.  Your job is to help create an environment to help support the selection of the good guys that like your location and make them as happy and productive as possible.

Brewed Aerated Compost Tea is alive and breathing and will “spoil” within a couple of hours without being constantly aerated and/or diluted.  In Compost Extract or Liquid Compost  the microbes have not been fed so they are not “breathing hard” and can store for several days with a little planning.   We think all Compost Tea/Extract goes out better with Activated Effective Microorganisms added!
