Preliminary results are in comparing Activated Aervated Compost Tea and conventional fertilizer. http://www.huffingtonpost.com/maria-rodale/organic-vs-chemical-lawn_b_3648932.html Do not expect to get the same results unless you really know how to brew AACT for turf. Under the direction of Elaine Ingham, Rodale has greatly improved how they make compost. James Sotillo has been brewing high quality AACT for a decade. All compost and all AACT are not created equal.
