This PDF-dashboard shows the status of your fields on a weekly basis. We will show this in different ways:
1) The first way is with a general overview of field heterogeneity using ‘variation’ – a higher number indicates more differences between plants in the same field.
2) The second map shows a normal image of the latest week in colour, of the demo fields.
3) Then come the maps per field, which show the status for three weeks ago, two weeks ago, last week, and this week, as well as a percentage difference map between last week and this week. The percentage difference maps shows the relative difference in growth over the last week, with positive numbers showing growth, and negative numbers showing decline.
4) Below the maps are graphs that show how each pivot quadrant is doing, measured through the chlorophyll index.
