So, what does this say about things that are labeled "Pro" or "Professional"? It's all marketing. Seed from a particular cultivar or mix is still that cultivar or mix, even if it says "Professional" or "Cheap-*** Homeowner Stuff" on the bag. I think we had a thread about this type of subject once with RoundUp. Whether you use the stuff off the shelf at Wal-Mart or you buy it directly from Monsanto, if you follow the label directions, you apply the same amount of the same stuff. The marketing language on the container doesn't impact the results. Similarly, you can deliver the same quality with a dry program that you can with a liquid program. I used to use this as a conversation starter at extension presentations: which is better, liquid or dry fert? The answer: They're the SAME! It's all fertilizer -- it all breaks down to the same simple compounds for plant uptake. Urea is urea, whether it comes from prill urea, SCU, PCU, PCSCU, or liquid urea. I think the cool things about fertilizers is that there are hundreds of ways to get the same end result, so you can pick and choose what fits your needs the best.
