      This is basic stuff that is taught in College level soil science and agronomy classes. That combined with the fact that I can create micronutrient deficiencies in ornamental plants by feeding them heavy rates of phosphorus is enough for me. I remember being warned about it sitting in an agronomy class at 7:30 in the morning. I also remember the lab experiment where we got to grow corn with various nutritional imbalances and deficiencies. Maybe it is very hard to cause it. But once it happens, it is really hard to fix. Phosphorus is almost forever. I have soils so full of phosphorus thanks to the misuse of ag grade fertilizers, that the only nutrients needed are N, K and a lot of micronutrients.

      Phosphorus forms insoluble compounds with many micronutrients. Iron phosphate and zinc phosphate come to mind. Another thing to think about is how close to and similar phosphorus is to arsenic. At some point in time phosphorus becomes a metabolic poison like arsenic.

      Sorry, no. I just tried the stuff at Home Depot. I'm pretty sure it was Ortho, but I highly doubt there's much of a difference between brands. Honestly, I had about as much luck with canola oil, although canola is more likely to damage a plant in hot weather.
