We have been fortunate to have Katelyn Duncan as a part of our agronomy group now for a little over a year. Being an agronomist and also actively involved in their family farm operations outside of Regina, she is familiar with both the science and the hands on operations of farming. Earlier in the spring she posted up a tweet about sprayer cleanout with a view of preventing potentially crop damaging chemical residue contamination of their sprayer. She hit on an issue which has caused large losses for farmers over the last few years, and I asked her if she would be interested writing an article about the subject for this blog. She has written an excellent article and at this time of year it is a timely post. Click on the link below to view the article. Thanks for this contribution Katey!
