Thoughts from someone who spends life amongst the weeds
Robert C Kniss Bob, to most. But also Bobby, Kniss Kid, Uncle Bob. Grandpa Bob. Dad. Born July 31, 1945, he would have turned 80 years old today. He knew every fishing hole on the Red Willow, and every dirt road in Morrill County. For as long as I can remember, he d spend the better part of every day driving around in his pickup checking crops and checking on people. I suspect there are county…

I love agriculture. I grew up on an irrigated farm in the panhandle of Nebraska. My grandma grandpa, my aunts uncles, and my mom dad all farmed together, and three of our families lived within 1 mile of each other. I grew up farming the same land that my grandparents farmed while raising my dad his siblings. Most of my cousins and most of the friends I grew up with also grew up on farms. It
A study published in the Proceedings of the National Academy of Sciences (PNAS) has both glyphosate and autism in the title, and so it is sure to re-ignite a firestorm around the world s most widely used herbicide. The abstract of the article states that the authors found ASD-like behavioral abnormalities in juvenile offspring after maternal exposure to high levels of formulated glyphosate.…
Each point represents crop yield from one state in one year. The transparency level indicates the number of acres produced; darker points mean more acres, and lighter points mean fewer acres. All data from USDA-NASS. In the remaining figures, crop acres are represented by the size of the point; larger circles mean more acres, smaller circles mean fewer acres. Red line is the state-level yield…
Yesterday, I posted some photos to twitter, and have been asked to provide a little bit of context. My goal with these photos was not to raise an alarm I was simply trying to provide a visual illustration of how susceptible soybean plants are to the herbicide dicamba. Recently, I published a meta-analysis of published literature on this topic. In that paper, I estimated the amount of dicamba…
It s a simple question. And at first glance it seems like there should be a simple answer to this simple question. We have planted millions of acres of genetically-engineered (GE) crops, a vast majority of which are resistant to herbicides. In the U.S., we ve collected lots of herbicide sales and usage data, spanning the entire time period when GE herbicide-resistant crops went from non-existent…
Palmer amaranth is native to the southwestern United States, and has been recognized as a problematic weed in the southwest and southeastern US for many years. Each year, this species seems to move further north. I ve been trying to keep an accurate state-level distribution map for this weed, and thought I d post it here for anyone else who might be interested. Data sources: PLANTS database…
Recently, a jury in San Francisco, California recommended that Monsanto be forced to pay $289 million to a man who has been diagnosed with non-Hodgkin lymphoma. It was a pretty stunning result from a court case that has been watched very closely. I haven t read the court transcripts, and I don t know what the jury was told or what was withheld from them. And I have no desire to make accusations…
This has been a difficult year. One year ago, I learned that my best friend had died in a motorcycle accident. He was traveling to a meeting in California a meeting that I was also attending. I found out about Gustavo s passing just a few seconds before the flight attendant made me put my phone into airplane mode. I was alone, without the ability to communicate, and I d just been told I would…
