Evolu­tion of Ag Tech

A guest contri­bu­tion from the Amer­ican Furrow: agri­cul­tural jour­nalist Katie Knapp takes a highly personal look at tech­no­log­ical devel­op­ments in farming, from the elec­tronics of the 1970s to GPS guid­ance, drones, sensors, robotics and arti­fi­cial intel­li­gence. Agri­cul­tural tech­nology is helping farmers work more effi­ciently, sustain­ably and precisely, both in the field and in the barn. Look at the key tech­no­log­ical mile­stones and the chal­lenges ahead.

“Most people over­es­ti­mate what they can do in a year and under­es­ti­mate what they can do in ten.” Jeremy Groeteke, global head of IT and digital strategy for Syngenta® shared this quote attrib­uted to Bill Gates at a confer­ence last summer. Groeteke went on to talk about advances and different use cases for gener­a­tive arti­fi­cial intel­li­gence (e.g. ChatGPT) in agri­cul­ture. My mind, however, took me back to my high school FFA public speaking days.

I gave a speech on BT corn only a few years after the trait was commer­cial­ized for farmers like my dad to plant. I wrote that speech on a big Gateway desktop computer plugged into the wall in our kitchen and saved it to either a floppy disk or a re-writable CD. The quote Groeteke shared could not be more true in terms of tech­nology devel­op­ment. That early 2000s Gateway seems ancient now. The same is true for the tools you’re using on your farms.

Farmers have been running their oper­a­tions on renew­able fuels including ethanol and biodiesel and feeding the grid with alter­na­tive energy in increasing amounts for the past 50 years.
The global stan­dard for lighting now, LED lights, became commer­cially avail­able in the late 1990s. Having the ability to use single-color LED lights allows for hydro­ponic produce to be success­fully grown indoors.

In the March 1976 issue of the Amer­ican Furrow, regional editor Kim Allen wrote a story about elec­tronics coming to the farm. In it, he listed industry-wide advances like closed-circuit tele­vi­sion, portable calcu­la­tors, RFID implants, and two-way radios. He also mentioned specific exam­ples like combine leveling tech­nology and auto­matic fruit sorters. If that article had been written a few decades prior, it would have included inno­va­tions such as on-farm grain drying bins and elec­tric fences. A couple decades before that—or nearly a century ago—the list would have included hydraulic lift systems on farm imple­ments and, simply, on-farm elec­tricity thanks to the New Deal Rural Elec­tri­fi­ca­tion Admin­is­tra­tion.

Grain farmers no longer need to keep their hands on the wheel thanks to auto-steer tech­nology. Combine sensors read out the mois­ture, yield, and numerous other stats in real time.

Rotary milking parlors are not new. They were first intro­duced in 1930 but without much adop­tion. Today’s auto­matic versions, designed to maxi­mize cow comfort and effi­ciency, can hold upwards of 80 cows at once.

Boehringer Ingelheim’s SoundTalks is one of numerous digital moni­toring tools that help detect animal health issues.

Since the Black­berry came on the market in 1999, smart phones and watches have become ubiq­ui­tous, extremely capable tools.

Fast-forward to today, farmers like my dad and you rely on high-speed internet and phones packed with computing power to do many tasks around the farm. Words like “preci­sion,” “smart,” and “auto” accom­pany much of what you touch daily.

Billions of dollars are being invested in the United States ag tech sector alone to help develop more ways for farmers to increase effi­ciency, effec­tive­ness, and sustain­ability. The researchers, scien­tists, and inno­va­tors are working to curb the chal­lenges of today’s and tomorrow’s farmers—issues like hard-to-find labor, high cost of doing busi­ness, and weather extremes.

“The advent of GPS has been the biggest game changer since I started farming in the 70s,” says my dad, Ken Knapp of Magnolia, Ill. “So much useful tech­nology has come because of it, and what has been amazing is that we have often found different and better uses for the new tech­nology than why it was orig­i­nally devel­oped.”

Auto­matic lighting, temper­a­ture-controlled fans, and egg-collecting conveyors are among the advances that allow young farmers like Jacob Rowland to operate large barns with minimal addi­tional staff.
Japanese farmers first used drones to spray rice fields in the late 1980s. Now farmers around the world use them for scouting, spraying, and seeding.
Internet-connected weather and soil mois­ture moni­tors allow farmers to know the precise condi­tions of each field.

In the field

Beyond GPS and the signif­i­cant devel­op­ments in genetics and pest control prod­ucts, farmers are raising crops indoors using special­ized LED lights. Some of you are moni­toring crop health with drone cameras more sophis­ti­cated than many profes­sional photog­ra­phers use and then applying crop protec­tion with vari­able-rate spray drones. And you are powering a In the field. Beyond GPS and the signif­i­cant devel­op­ments in genetics and pest control prod­ucts, farmers are raising crops indoors using special­ized LED lights. Some of you are moni­toring crop health with drone cameras more sophis­ti­cated than many profes­sional photog­ra­phers use and then applying crop protec­tion with vari­able-rate spray drones. And you are powering a lot of your oper­a­tion and those at the other end of the line with alter­na­tive energy.

In the barn

In that same 1976 issue where the article reprinted this month ran, other arti­cles detailed how farmers were finding success with arti­fi­cial insem­i­na­tion in swine and beef embryo trans­fers. Now producers are speeding up genetic progress with genomics testing and pheno­type measuring.
You can also use count­less tools to measure animal health based on the sound inside the barn or data being captured by wear­able devices, much like the smart watches we wear. And barns equipped with robots at nearly every turn—from feeding systems to sorting and grading stations—are quickly becoming the norm.

Glyphosate-resis­tant corn came on the market in 1996. Since then, many traits have been devel­oped and the U.S. average yield has gone from 127 to 187 bushels per acre, according to the USDA.

Vari­able-rate tech­nology intro­duced in the 1990s helps farmers reduce input usage.

Like corn, soybean genetic tech­nology advances have led to a 68% yield increase in the USA since 1996.

Tool not replace­ment

While writing this article, I was on a press tour visiting farmers and researchers in Kenya. There, the Inter­na­tional Live­stock Research Insti­tute commu­ni­ca­tions lead, Michael Victor, summed up the changes since Allen’s 1976 article. “Fifty years ago, the focus was on the Green Revo­lu­tion and feeding every­body, so really on produc­tivity. But now, as we know, a lot of the issues are food system and climate related, so we’re really focused on how we increase produc­tivity and feed the growing popu­la­tion without destroying the envi­ron­ment,” Victor says. His team is the live­stock-focused arm of CGIAR, a global ag research part­ner­ship working to improve food secu­rity.

Grading and sorting tech­nology advances in egg and produce packing houses has reduced the labor needs signif­i­cantly.
Meat inspec­tors now can grade each carcass digi­tally.

On the same trip to Kenya, the general manager of a large poultry farm said a very impor­tant and universal caveat about all the tech­nology he employs. “Not one of my farms is the same, so I have to adapt to each different situ­a­tion. If I use too much tech­nology, it takes the farming and the fun out of it. You must be hands-on,” says Nicolas Grobler while showing me around his laying hen barns. “God’s given us all the five best computer systems that we can have. I don’t need a fancy computer in the chicken house to tell me there’s some­thing wrong. If you just observe, smell, taste, feel, the chickens will tell you what’s wrong.” Fifty years from now, our smart phones will likely seem as quaint as portable calcu­la­tors do now, but knowing where to draw the line with tech­nology use will be just as impor­tant.

The 1976 article from The Furrow

In the Amer­ican maga­zine The Furrow, regional editor Kim Allen wrote an article in March 1976 about the advent of elec­tronics in agri­cul­ture. In it, he listed industry-wide advances such as video surveil­lance, hand­held calcu­la­tors, RFID tags and two-way radios.
