Not till it in to corn. Never understood the guys putting it into beans. If it had some alfalfa in it you have a bunch of n there plus the benefit of tap and branch roots from the alfalfa and grasses. Kill the stand when there is about 2" of growth and maybe a cheap residual like atraziene. Plan on a second pass when the corn is maybe V4-6 or when the weed escapes look like they are ready to be killed. The corn will then canopy and pretty much take care of weed control but keep an eye on it. There are many places to figure out what your N availability will be but more than likely it will be more than half your needs. Test for K a poorly fertilized hay crop will pull K down or a well fertilized crop will have good levels of K. Coulters of the planter would be helpful to loosen the top which can be hard. They also let rubber press wheels do the job. Spikes would be ideal but the if you don't want them on jack the pressure way up. You will love the stands if it is a smooth field the units hardly move during planting.
