There were about a dozen or so of us at Elaine Ingham's compost tea class yesterday. It was great, wish I had the time to be there for the full 5 day course. Maybe someone else will chime in about those days. Probably the most important thing I learned was that heat & UV does not have the detrimental effect on microbes as I had thought & have heard mentioned many times. Elaine recounted a study she had done where they were applying tea with one of those large pivot sprayers used in agriculture. It took 36 hours for the sprayer to complete its circuit. She suggested to the farmer that it should be shut down between 10 AM & 2 PM during the hottest & most intense UV hours. Farmer said no. She tested foliar for live microbes before & after, all areas increased by the same amount regardless of temp & UV at time of application.
