Yep, that was it, thanks for refreshing my memory Rob. And you pointed out the key points that I now can remember a little more clearly. SA floratam had the ability in our soils to create the deepest roots during the peak growth periods. And if I remember correctly Palmetto had next deepest rooting and also and as a result showed a lower level of leaching? Well of the cultivators commonly available to us commercially. And if I recall correctly, this was actually a study that was concerned with drought tolerance that brought the current research that is underway about the nutrient uptake/leaching. The current information being given through the extension also says that if you apply the orange county guidelines for fertilizer applications - virtually all of the nutrients will be used. I do not remember them handing out any information on this do you Rob? If you they did and you have it give me a copy and I will post for everyone to discuss here.
