these systems,that a corn-soybean system

I would say with almost any of these systems,that a corn-soybean system really was not sustainable. Continuous corn, however, was in certain flatter fields. OK, about done with my slides, David. I put this up here just to show time variable K. So you can take a look. We've got California, South Dakota, Massachusetts,and Tennessee. So you see how, if we've got a base value of K whichis looking at permeability or soil structure organic matter,all   Cognimaxx xl go into the nomograph to build your K factor that youpull out of your [INAUDIBLE] database. So it varies throughout the year. In South Dakota, early in the year it's very small,versus you get in the middle of the year, it's much higher. So it's just something to be aware of as far as keepingit covered. Your soil conditions, your structure, all those thingsimportant to soil health will varydepending on the area of the country you're in. Some of the things that are being worked on with K factor--Linda and Giulio and others are working with ARSto improve the K erodability prediction for a higher clayorganic and other soils. Some of those, they're not as comfortable with howthey fall out, so they need a little more work and research. Also,
