How much do I mix in 1 gallon to water into the soil in organic agriculture applications?

For soil drench applications we recommend 25 grams per gallon, and for foliar spray applications we recommend 7 grams dissolved in warm water per gallon. Thanks, John

Can this be used in foliar spray applications / organic agriculture spray? If so, what is amount to mix in 1 gal?

Absolutely, it will work very well as a foliar spray. You will want to mix in 1/2 a tsp or 3.0 grams per gallon of water - we recommend using non-chlorinated water where available. Thanks, John
