Creating N-Insight Reports
Select the "N-Insight" icon from the left navigation bar and click the + button to create a new field or select a grower and field from the dropdown to run N-Insight on a field that has already been created. Once a field has been created or selected from the dropdown, some general information about the current management of the field will need to be provided.
Planting dates for the previous five growing season can also be entered under them map.
Once the information is entered, click the "Save & Run" button and the report will be processed. When finished, click the "Report" link on the right to view the N-Insight report.
After clicking the "Report" link, the N-Insight report will be displayed and users will have the option to view the report as a PDF or enroll the field in Adapt-N by clicking the appropriate link.
Understanding N-Insight Report
N-Insight is a great way to show the year-to-year variability of zones and how efficiently those zones use nitrogen. The N-Insight Report shown below was ran using an N rate of 175 lbs applied in the fall.
Near the top of the report written in pink, you can see that the average per acre loss of total N was 142 lbs for the 5 year scenario. It's important to understand that this is TOTAL N (losses from both commercially applied fertilizer as well as mineralized nitrogen) and not just applied N. Below this you can see the average applied N loss of 105 lbs or 59% of applied N.
The report also shows you a map of the different soil texture zones in the field and a bar graph showing N losses in each zone during each year.
In this example, 2013 had the highest nitrogen losses with the current management practices used on this field with 71% of applied N being lost. Both the clay loam (blue) and loam (green) zones in this field were deficient of N which is signified by the ear of corn in each zones bar in the graph. This resulted in a weighted average total N loss of 166 lbs in 2013.
For comparison, 2015 had lower nitrogen losses with 45% of applied N being lost. However, in 2015 the loam zone had a surplus of N which is signified by the "N" in the green bar while the clay loam zone was deficient of N (ear of corn in the blue bar). This resulted in a weighted average total N loss of 106 lbs in 2015.
