AU­TOMAT­ING AGRI­CUL­TURE

The Beaufort Gazette (Sunday) - - Front Page - BY MIRIAM JOR­DAN

As im­mi­grants grow scarce, farm­ers are turn­ing to ro­bots to har­vest and process their crops.

As a boy, Abel Mon­toya re­mem­bers his fa­ther ar­riv­ing home from the let­tuce fields each evening, the pic­ture of ex­haus­tion, mud caked knee-high on his trousers. “Dad wanted me to stay away from man­ual la­bor. He was keen for me to stick to the books,” Mon­toya said. So he did, and went to col­lege.

Yet Mon­toya, a 28-yearold im­mi­grant’s son, re­cently took a job at a let­tuce-pack­ing fa­cil­ity, where it is wet, loud, freez­ing – and much of the work is phys­i­cally tax­ing, even mind-numb­ing.

Now, though, he can del­e­gate some of the worst work to ro­bots.

Mon­toya is among a new gen­er­a­tion of farm­work­ers here at Tay­lor Farms, one of the world’s largest pro­duc­ers and sell­ers of fresh-cut veg­eta­bles, which re­cently un­veiled a fleet of ro­bots de­signed to re­place hu­mans – one of the agri­cul­ture in­dus­try’s lat­est an­swers to a di­min­ish­ing sup­ply of im­mi­grant la­bor.

The smart ma­chines can as­sem­ble 60 to 80 salad bags a minute, dou­ble the out­put of a worker.

En­list­ing ro­bots made sound eco­nomic sense, Tay­lor Farms of­fi­cials said, for a com­pany seek­ing to cap­i­tal­ize on Amer­i­cans’ in­sa­tiable ap­petite for healthy fare at a time when it can­not re­cruit enough peo­ple to work in the fields or the fac­tory.

A decade ago, peo­ple lined up by the hun­dreds for jobs at pack­ing houses in Cal­i­for­nia and Ari­zona dur­ing the let­tuce sea­son. No more.

“Our work­force is get­ting older,” said Mark Bor­man, chief op­er­at­ing of­fi­cer of Tay­lor Farms. “We aren’t at­tract­ing young peo­ple to our in­dus­try. We aren’t get­ting an in­flux of im­mi­grants. How do we deal with that? In­no­va­tion.”

Mov­ing up the tech­nol­ogy lad­der cre­ates higher-skilled po­si­tions that can at­tract young peo­ple such as Mon­toya, who is fin­ish­ing a com­puter science de­gree, and bol­ster re­ten­tion of vet­eran em­ploy­ees who re­ceive new train­ing to ad­vance their ca­reers.

“We are mak­ing bet­ter jobs that we hope ap­peal to a broader range of peo­ple,” Bor­man said.

In a 2017 sur­vey of farm­ers by the Cal­i­for­nia Farm Bu­reau Fed­er­a­tion, 55 per­cent re­ported la­bor short­ages and the fig­ure was nearly 70 per­cent for those who de­pend on sea­sonal work­ers. Wage in­creases in re­cent years have not com­pen­sated for the short­fall, grow­ers said.

Tay­lor Farms brings in about 200 work­ers a year on H-2A guest worker visas, about 10 per­cent of its sea­sonal la­bor force. “The pro­gram is not al­ways de­pend­able and our items are per­ish­able,” said Chris Rot­ticci, who runs the har­vest au­to­ma­tion divi­sion of Tay­lor Farms, which is also look­ing for ways to re­place hu­mans. “But we have to do it. We don’t have enough peo­ple.”

Ideally, grow­ers say, Con­gress would pass a bill to le­gal­ize farm­work­ers in the coun­try il­le­gally and en­cour­age them to stay in the fields, as well as in­clude pro­vi­sions to en­sure a steady flow of sea­sonal work­ers who could come and go with rel­a­tive ease.

Cal­i­for­nia’s $54 bil­lion agri­cul­tural in­dus­try can­not af­ford to wait. As the coun­try’s epi­cen­ter of both tech­nol­ogy and agri­cul­ture, the state is lead­ing the move to au­to­mate in the fields and pack­ing plants.

Driscoll’s, the berry ti­tan based in Wat­sonville, Cal­i­for­nia, has in­vested in sev­eral robotic straw­berry har­vest­ing star­tups, in- clud­ing Agrobot, which uses imag­ing tech­nol­ogy to as­sess a berry’s ripeness be­fore it is har­vested. It is cur­rently in test phase.

Bart­ley Walker, whose fam­ily busi­ness rents and sells trac­tors, now of­fers a robotic hoe­ing ma­chine with a de­tec­tion cam­era ca­pa­ble of iden­ti­fy­ing the pesky weeds that sprout be­tween row crops like broc­coli and cauliflower.

“The weeder is not as pre­cise as a hu­man with a hoe,” Walker said, “but it ex­tracts 90 per­cent of the weeds.” What is more, one ma­chine re­places 11 work­ers.

About 60 per­cent of the ro­maine let­tuce and half of all cab­bage and cel­ery pro­duced by Tay­lor Farms are har­vested with au­to­mated sys­tems. The com­pany has part­nered with an in­no­va­tion firm, which pre­vi­ously fo­cused on au­to­mated ve­hi­cle as­sem­bly, to de­velop a ma­chine to be­gin har­vest­ing broc­coli and ice­berg let­tuce within two years.

All told, the com­pany plans to dou­ble the num­ber of au­to­mated har­vesters, which cost about $ 750,000 each, in the fields each year – un­til nearly ev­ery­thing can be ma­chine-picked.

Wheat, soy­bean and cot­ton crops have long used au­to­ma­tion. Del­i­cate fruit, like peaches, plums and rasp­ber­ries, as well as veg­eta­bles like as­para­gus and fen­nel, will re­main la­bor in­ten­sive for the fore­see­able fu­ture.

It is dif­fi­cult to re­place the hu­man eye and hand – and tech­nol­ogy is still in its in­fancy.

On Oct. 4, an au­to­mated har­vest­ing ma­chine at Tay­lor Farms in Sali­nas, Calif., uses a high pres­sure wa­ter stream to cut ro­maine let­tuce heads. Tay­lor Farms re­cently un­veiled a fleet of ro­bots de­signed to re­place hu­mans – one of the agri­cul­ture in­dus­try’s lat­est an­swers to a di­min­ish­ing sup­ply of im­mi­grant la­bor.
