I got my hands on alot of alfalfa meal and corn meal and have a few questions. 1) How much of either of these items to apply per 1000sqft? 2) How often should I apply? 3) Can or should I mix these items? This is on St. Augustine with an active fungus. Only synthetics have been applied for the past 5 years(nothing in 09). This lawn is irrigated. I have on hand ICT compost tea and NPP.
