A CENTURY OF INNOVATION IN THE FIELD How growers have used mechanization, automation and robotics to keep
agriculture productive, resilient and sustainable By Ben Palone, Senior Commercialization Director, Innovation
For 100 years, Western Growers members have faced the same fundamental challenge: produce more food of higher quality, with limited land, water, labor and time. The tools have changed dramatically, but the grower’s mindset has not. Growers observe a problem, test a solution, measure the result and improve the system. Long before anyone used the term “agtech,” growers were already innovators. That history matters. Agriculture’s technological progress is sometimes described as though innovation arrived recently from outside the farm. In reality, many of the industry’s most important advances succeeded because growers adapted them to commercial conditions. Tractors, precision planters, mechanical harvesters, refrigerated transportation, drip irrigation and improved genetics all became valuable only after growers proved where they fit, changed their operations and accepted the risk of doing something differently. Innovation Across Crops Consider the evolution of California almonds. Shakers, sweepers and pickup machines transformed harvest from a labor-intensive process into a coordinated mechanical system. Microirrigation, soil-moisture monitoring and pressure-compensating emitters later gave growers far greater control over when and where water and nutrients were applied. In table grapes, trellis design, canopy management, field packing and cold-chain improvements increased quality and helped fruit travel farther while arriving in better condition. The lettuce industry tells an equally powerful story. A century ago, lettuce was packed in wooden crates, top-iced and shipped east by rail. Better railcars, refrigeration, vacuum cooling, packaging and logistics expanded markets and changed what consumers could expect from fresh produce. None of those advances was a novelty for its own sake. Each solved a grower problem: shelf life, quality, labor, distance or cost. Genetics has been just as important as steel and electronics. Plant breeders have improved yield, uniformity, shelf life, flavor and resistance to pests and disease. In apples and stone fruit, genetics combined with dwarfing rootstocks and two-dimensional trellis systems is creating narrower, more uniform canopies. Those systems improve light distribution and worker access while making precision spraying, mechanical pruning and future robotic harvesting more achievable.
Doing More with Water Inputs and Information Irrigation may be the clearest example of technology becoming a management system. Permanent-crop growers moved from broad applications toward drip and micro-sprinklers, then added weather data, soil and plant sensors, remote valves, telemetry and variable-rate control. The objective is not simply to use less water. It is to place the right amount in the right location at the right time to protect yield, quality and long-term orchard or vineyard health. That capability has become more important as regulation has grown more complex. Under requirements such as the Sustainable Groundwater Management Act (SGMA), growers need better information about pumping, allocation and crop demand. Digital records also support nutrient management, pesticide applications, traceability and compliance reporting. Technology cannot remove regulation, but it can reduce the time and uncertainty required to manage it—and help growers document responsible practices with defensible data. From Hand Crews to Plant Level Decisions In bedded vegetable production, innovation begins before the crop emerges. Growers choose between direct seeding and transplants based on crop, season, cost, stand establishment and harvest goals. Precision planters and improved transplanters have increased uniformity, which matters because nearly every downstream operation works better when plants are consistently spaced. Thinning and weeding show how quickly field work can change. Hand crews once made nearly every plant- selection decision with a hoe. Today, automated thinners use cameras and targeted treatments to establish the desired spacing. Automated weeders combine mechanical tools, precision sprays, lasers or other energy sources with vision systems that distinguish crop from weed. These machines do more than replace a task. They can reduce crop injury, target inputs and create a repeatable record of field performance while helping growers manage rising labor costs and limited crew availability. Crop protection is expanding beyond conventional application methods as well. Ultraviolet-C systems are being evaluated and deployed in selected crops to suppress powdery mildew, offering another tool alongside synthetic chemistry, biological products and
