LandMark Implement 2019 Test Plots
LandMark has partnered with 360 Yield Center who offers products focused on managing the nitrogen applied to corn to get the greatest benefit. In many cases, these methods are very different than those that are used in most operations. We have set out to work with some of our local customers to compare nitrogen management practices with the intent to keep all other variables the same, as much as possible.
With the variety of field types and irrigation practices we see across LandMark’s footprint, we have spread out the plots into different areas including both dryland and irrigated fields. We are not just focused on growing the most bushels, but doing so in the most profitable manner.
