In the past my soil tests have sometimes come up with a need for Boron, Sulphur, Zinc and Manganese.

In recent years after grazing the only micro which shows up as "Low" usually is Boron. I get usually 2 lb/a blended in with the DAP and 0-0-60 in a spinner cart and dry spread just ahead of strip tilling in the spring.  I would love to have an air cart and blow it in the strip but not near enough land to warrant a Montag system.

The coop has a new stationary dry fertilizer blender and it is amazing how uniformly they can mix a couple pounds of something into a couple tons of something else as it is loaded in a trailer cart.
