InField Updates is an app tool that provides nutritionists, agronomists, and growers timely fresh chopped corn statistics on a map to help determine the optimal harvest timeline. Users can easily submit fresh corn silage samples**, using the FeedScan app, to gather moisture, protein, NDF, and starch information on their sample. In turn, the sample moisture and NDF is anonymously plotted on the map for the community to see what corn is looking like in various areas around the US.

Please note: Location services must be turned to "on" on the device (phone, tablet) used to submit the samples for this tool.
