Great post and concept. I can attest to foliar applications. Last season my soil tests came back with low trace elements. Instead of trying to throw rock dust on the soil and water in with teas, hoping it would become plant available sometime that season I foliar sprayed MicroPak from American Eco Agriculture with fantastic results. Really improved the quality of the herb, and now in the off season I will correct the soil deficiency.
I am at a little bit of a loss with this statement: "Humidity and temperature have a direct relationship with absorption of nutrients and as they increase, penetration also increases. The total amount of time the nutrient is in contact with the leaf is critical. Optimum pH is a factor that varies from nutrient to nutrient and most good formulators recognize the need to have optimum pH for the nutrient used."
and other statements made about optimal conditions for foliar sprays.......... I am sure at a microscopic level, certain times of the day and certain temps are more conducive to immediate uptake. However I imagine the phylloplane just at the rhizosphere, where the microbes will take care of the break down and the transfer of nutrients to the plant. I wouldn't think it would matter if the plant surface is still wet from the foliar application, the nutrients are still on the leaf surface, along with the microbes to break it down.
Something I think about while smoking joints staring at the plants.
@Bulldog11 well you blew my cover!!!! Yhought I was the only one that got stoned and stared at the ladies. :cool:
