In fall 2005 UWEX began using the Maximum Return to N (MRTN) approach to make N rate suggestions for corn. Since that time, both corn and N prices have fluctuated. Currently N prices are high and may continue to move upward as we approach spring. Several of our clientele have asked for an expanded N:corn price ratio chart to reflect current and potential prices. Well, we listened and here it is.

Alfalfa is a key crop in many rotations within Wisconsin, but if not successfully removed it can be troublesome in subsequent crops. This is especially true in no-till systems. This experiment was conducted on Roundup Ready alfalfa, as concern exists in the ability to remove this crop without the use of glyphosate as this is the most common herbicide used to remove alfalfa.
