Hello All,

I have planted 300 new 2 and 3 gallon highbush blueberry plants (chandler, blue ray, blue crop, jersey and duke) in a new orchard I put in. I already have 20 mature bushes that do well but have been lowering in their yield the past few years. I haven't fertilized in a few years and need to get the plants back to productive levels. I have in-line drip irrigation beneath pine and hemlock bark much beds that give my rows water retention in the sandy and nicely acidic soil here. But they lack nitrogen. I need to know where I can get liquid form Ammonium Sulfate I can ciphon into my drip irrigation system with a dosatron. Does anyone know a source(s)?
