Know-how can get rid of a lot of tedious, routine labor — a way of life payoff that may assist persuade a youthful era to remain placed on household farms slightly than promote out.
BULGER, Pa. — About 150 Jersey cows within the rolling terrain at Rivendale Farms in Bulger, some 25 miles west of Pittsburgh, put on FitBit-like collars that monitor their motion, consuming and rumination patterns. They’re milked not by people however by robotic machines.
A close-by greenhouse, about a quarter-acre in measurement and full of salad-bowl crops like kale, arugula and child carrots, is automated. The temperature, humidity and daylight are managed by sensors and retractable metallic screens. And shortly, small robots might roam the farm’s eight acres of vegetable crops outdoor to identify illness and pluck weeds.
Farming in America is more and more a high-tech endeavor. Combines guided by GPS, drones, satellite tv for pc imagery, soil sensors and supercomputers all assist the nation’s meals manufacturing. But that know-how is especially tailor-made for giant industrial farms, the place fields stretch so far as the attention can see.
Rivendale Farms, which has simply accomplished its first yr of full operations, presents a glimpse of know-how coming obtainable for smaller farms.
Know-how for large farms is all about growing yields and slicing prices. For smaller farms, too, effectivity is paramount. However know-how may also remove a lot of tedious, routine labor — a way of life payoff that may assist persuade a youthful era to remain placed on household farms fairly than promote out.
Smaller farms sometimes increase specialty crops on restricted acreage. Specialty farming requires a scaled-down strategy, just like the small robots being developed for Rivendale by scientists at close by Carnegie Mellon College and the increasing array of kit from the “slow tools” motion, a group of farmers and engineers designing reasonably priced instruments for small farms.
The aim at Rivendale, stated Thomas Tull, the farm’s proprietor, is to create a “boutique, cutting-edge farm, enabled by technology, that produces great food.”
Rivendale can afford its mixture of cutting-edge business know-how and science experiments as a result of Tull is a billionaire serial entrepreneur, investor in tech-related ventures and former movie producer. He’s additionally on the board of Carnegie Mellon. He has spent a number of million dollars on Rivendale thus far. However the plan, Tull stated, is for the farm to develop into self-sustaining by 2020.
So Rivendale can attempt extra issues directly than others can. However its efforts, specialists say, are a part of a broader development amongst small farmers looking for to boost wholesome meals and livestock utilizing much less fossil gasoline, fertilizer and processed feed.
“We’re seeing greater use of modern technology and tools in smaller, soil-based farming, and that vision is being wholeheartedly embraced at Rivendale,” stated Jack Algiere, farm director at Stone Barns Middle for Meals and Agriculture, a nonprofit farm in Pocantico Hills, New York, that has been a main advocate for sustainable agriculture on small farms.
Tull purchased the land in 2015, and development began the subsequent yr. It’s now a diversified operation with milking cows, breeding cows, vegetable crops, corn for feed, chickens, even honeybees.
Rivendale, together with pasture land, cowl crops and woods, spans 175 acres. Farming in America has been consolidating for many years, with the typical measurement of a farm being 444 acres in 2017, in response to authorities statistics. And greater than half of the worth produced by the nation’s agricultural sector is generated by a small fraction of very giant farms, 2,660 acres on common.
Rivendale’s milk, eggs and produce are bought to native eating places and motels. It additionally provides meals to the Pittsburgh Pirates and the Pittsburgh Steelers, during which Tull is a part-owner.
Stroll into the dairy barn at Rivendale and there are not any individuals — solely cows, an automated feed system and three robotic milking machines.

The Rivendale cows are milked 4 occasions a day on common, once they really feel prepared, in contrast with the normal twice-a-day routine when people handle the milking. And its Jersey cows produce 15 % extra milk than the typical for the breed, with a larger protein and butterfat content material, stated Christine Grady, basic supervisor of Rivendale.
“They eat when they want, lie down when they want and feed when they want,” Grady stated. “And a happier cow produces more milk and better milk.”
It takes a week or two for the cows to get accustomed to the robotic milkers and the built-in incentives, stated Rodney Rankin, who leads the dairy operations. The milking stations have vanilla-flavored feed pellets, however a cow can’t simply come again repeatedly for the treats. Sensors and a scale — a cow’s weight can range by as much as 75 kilos in a day — forestall cows with out fairly full udders from getting in.
As soon as the cow is within the stall, the teats and udder are washed with little rotary brushes. Lasers scan and information the milk suction units onto every of the 4 teats. Milking time is six minutes on common. On the finish, the cow is sprayed with iodine and steam to wash its udder.
Robotic milkers have been out there for years. However the know-how has steadily improved, requiring far much less human help than a few years in the past.
The machines value about $200,000 every. With out them, and an automated feeding system, the milking barn at Rivendale would require 5 staff as an alternative of being primarily overseen by one, Grady stated.

The Rivendale robotic milking machines are made by Lely, a Dutch firm and a chief within the business. In some European nations, as much as 30 % of the cows are milked by machine, whereas in the USA the share is about 2 %, estimates Mathew Haan, a dairy know-how skilled at Pennsylvania State College’s agriculture extension program.
The hole, Haan stated, is essentially defined by extra beneficiant packages that help milk costs in addition to greater labor prices than in America. These two elements have inspired funding in automation in Europe.

In the USA, even large-herd producers with hundreds of cows in California, which have been labor-intensive operations, are starting to attempt robotic milking machines. That’s pushed partly by altering immigration insurance policies which will create a scarcity of farmworkers. However up to now, the primary market has been smaller operations with 120 to 240 milking cows, stated Steve Fried, Lely’s North American gross sales supervisor.
George Kantor, a senior methods scientist at Carnegie Mellon’s robotics institute, is main the trouble at Rivendale to develop “scouting robots” to determine illness and weeds within the vegetable subject, and then ship smartphone alerts if there’s a drawback.
His staff did area work and collected knowledge within the fall, then shifted to a college lab for the winter. Pc imaginative and prescient and machine studying, Kantor stated, might be deployed to differentiate wholesome crops from diseased ones and weeds.
A subsequent step can be to eliminate weeds. Natural farming avoids pesticides. And digging up or pulling weeds, Kantor stated, would require hand-like greedy and holding, a extra daunting robotic process, the place progress has been slower.
Some know-how at Rivendale is extra neat hack than high-tech. Susanna Meyer, head of crop manufacturing, is keen on a greens cutter whose engine is a battery-powered electrical drill, and a small electrical tiller referred to as the Tillie — one of many slow-tools implements.

Michael McGowen, a former employees scientist at Los Alamos Nationwide Laboratory, purchased a farm in Oregon a decade in the past, began rising greens and discovered there have been no reasonably priced instruments for small farms. So he designed his personal together with the Tillie, whose primary mannequin sells for $495, and arrange a enterprise, Carts and Instruments, in Corvallis, Oregon.
Johnny’s Chosen Seeds, a main distributor of the small-scale farming instruments, has seen that enterprise improve fivefold over the previous 10 years, stated Adam Lemieux, the corporate’s product supervisor for instruments and provides.
To most longtime farmers, AI stands for synthetic insemination, not digital wizardry. However a new era of household farmers is welcoming robotic assistants and smartphone apps.
“They have a different mindset, and they are all trying to figure out a path ahead for their family farms and where technology fits in,” stated Jeff Ainslie, a vice chairman of Purple Barn Consulting, which advises household farmers.
Scott Flory is one among them. After incomes his diploma in dairy science from Virginia Tech, Flory returned to his household farm in Dublin, Virginia, in 2009, with concepts for modernizing its operations.
Since then, the farm has put in 4 of the Lely robotic milkers, outfitted the cows with exercise trackers and doubled the variety of its milking cows to 240, with out including staff. The farm stays virtually completely a household affair, run by him, his spouse, Laura, and his mother and father, Dale and Janet.
“I wouldn’t be in the dairy business today without this stuff,” stated Flory, who’s 30.
At Rivendale, Tull, the proprietor, has little question that advancing know-how will rework smaller farms sometime.
However after intently observing the operations at Rivendale this previous yr, he stated, “You come away with a tremendous respect for farmers, and that the work is hard and complex. The key is getting the right mix of art and science.”
