Variable Rate Fertility Maps

Everyone understands what variable rate fertility is all about, but I thought it my be interesting to some to see what our variable rate maps look like on paper.  The controllers will run with just a computer file, but the paper maps help the driver to see areas that he can skip.  Also when you see it on paper it is pretty easy to see why this is a good idea.  We are just spreading fertilizer on a small part of the field that needs it.  We are  hoping to get a little yield boost by putting fertilizer where it is needed.  We are also hoping to save on input costs by not putting fertilizer on those areas that don't need it.  This is especially important for lime application because the availability of other nutrients depends on having proper lime levels. The spread zones have square corners in a good bit of this field because the soils are fairly uniform. 

On a different note, I will be attending Farm Progress Show in Decatur tomorrow so there will probably be no blog or a late blog.  Look for more later this week.
