 It's my dad and myself and we farm 2,500 acres. We're doing corn, soybeans, sugar beets and wheat and we do another 500 acres of custom work for other farms. We started looking at different ways to improve our soil structure and that is one thing we've incorporated on our farm now is a lot of these cover crops. And the reason we look at different cover crops is everything provides a little different benefit. For instance, we were messing around playing with some red clover and red clover is an excellent source if you want nitrogen for a corn crop. The problem is establishment and the cost to establish red clover is very difficult but it makes an excellent nitrogen source, free nitrogen for your crop the next year. We're not really experimenting anymore with the oil seed radish, we just use it. We've been doing that since 1999, we've been using oil seed radish on all our wheat acres. The rye is something we've been using for about 5 years now and that gets planted on every sugar beet acre. And next year we want to take it a step further, we're going to use rye on all our soybean acres as well when the soybeans come off from the rye unless it's planted to white wheat. And then we're also looking at incorporating peas or an Austrian winter pea mix in with the oil seed radish and that's, so the radish will have a benefit of the nitrogen so we don't have to apply any botan nitrogen that way. And then we've also been looking at oats which is an excellent source too. So I promise the oats is a very short timing of a window as to when you're going to plan it to get enough longevity to make it last throughout the winter months. And then we were looking at, in this field experiment we're doing with MSU there we're also looking at Sudangrass, oats of course, rye, every species is giving a different benefit to the soil. I guess it just depends on what the prescription you want for that particular field. What is the problem? Do you have nematodes? Don't you have nematodes? Do you get it from a nitrogen standpoint for the crop you're going to grow next year? Or are you looking at just trying to break up the hard pan? You know, do you have a soil structure problem? So that's why we're looking at maybe you may want to use multiple species within one cover crop mix on a field. We've been doing cover crops since 1999 and every year we just seems like we're adding something different increasing more here for cover crops, trying what we can to increase our soil structure at organic matter. And it seems like it's working, I mean like I said last year in a drought year we averaged on a thousand acres of beans in the mid-sixties so I said things aren't too bad.
