To sort of go along with Lowell's picture of soybeans with added N.....

 I did the same thing as he did. I had some extra N/S in the tank after wheat and went this field a few weeks before planting and sprayed it out along the border. It got rained in very well on top of last years winter wheat residue. 20gpa of a 27-0-0-5. I then no-till planted the tillage radish into the full residue load with a JD 1590. I put red clover under the radish.

 Just a couple days before this picture, I had applied 20gpa of urea solution 20-0-0. It got a half inch of rain to wash it in. We'll see if it makes any difference now.

 Never really grown a brassica before and I'm so used to legumes, the needed N just escaped me. Even if we only come out with our expenses, and the residual benefits of the radish are noticable, we may try raising them again as we have a few more fields that have near no wild radish history.

 You can tell right to the nozzle line the need for N of the radish.
