Week 10 Submission - Ryan Hanson - Hanson Ag Advantage

Ryan Hanson - Hanson Ag Advantage

This field is P9492AM planted on June 6^th.  This part of my area in Miner County has been very wet all year and a lot of corn didn’t get planted until that first week in June.  It continues to be wet.  Here about 2 weeks ago we started to notice yellow lines starting to show the length of the field, besides the yellowing of the low areas where the water sat too long.  I stopped by one day and always look at Pro to see what the field looks like.  Noticed some weird lines in the field so we walked out to investigate.  There was about 4 rows that were really yellow and then slowly improved.  They were staggered across the field like it was either a planter issue or a spreader issue.  After the customer talked with the applicator he admitted that they had a plugged center section on their air flow fertilizer applicator.  Which would have been nice to know when it happened.  We had this field planned for a split application of Nitrogen anyways, and the coop agreed to spread that for free since they had a screw up when they first spread it, which made the customer very happy.  So there is three images above.  The Siever’s Drone 7-29-19 was taken right after the urea application.  The first Crop Health Index screenshot was from 7-19-19 when we first noticed the lines.  Then there is the Crop Health Index Difference Map from 7-19-19 to 7-30-19.  He topdressed with urea on 7-25-19.  So on the difference map you can also see those lines had a significant swing to the positive side.  This is something that we probably would have not caught in time if we didn’t use Encirca Pro to help scout fields, given that most of the issue was in the far interior of the field.
