A long, long time ago… When I was a young agronomist, the biggest farm operation I worked with ran about 20,000 acres. It was made up of three brothers who, despite having only an 8th-grade education, were super smart when it came to farming. One day, we were talking about how much they needed for a pre-emerge herbicide. I calculated the gallons based on their acres, and they told me to increase the volume.
