New automated/robotic ag technologies are coming out all the time. Ever wonder how they function in the “real world” and whether they are cost effective? Western Growers recently released a case study report on the economic impact of Stout Industrial Technology, Inc.’s Smart Cultivator on overall weeding costs. The study tracked expenses, productivity, and labor savings of the machine operating over one year on five types of lettuce crops and 2,700 acres at Triangle Farms in Salinas, CA. It is a well done, detailed study with machine costs and labor savings broken down by crop type and acreage. It’s an easy read and worth the time for those interested in the economic and overall feasibility of automated mechanical weeding. Check it out here or by clicking the image below. I don’t want to be a spoiler, but I was surprised to learn that costs for hand weeding lettuce in Salinas, CA were so high - $525/acre (conventional) and $750/acre (organic) and that in these conditions, the return on the $330K investment for the machine was less than one year when used on 2,700 acres.
Stay tuned. Western Growers plans to release four more automation technology case study reports within the next year. Upcoming reports include grower case studies experiences with the automated weeding machine from Ecorobotix; and with autonomous ag platforms from Burro, GUSS Automation, and Bluewhite. Their first report, which examined the economics of Carbon Robotics’ Laser Weeder at the commercial scale, can be found here.

As the intense heat of the Yuma summer finally fades, cooler days bring the promise of lush fields which set the stage for a vibrant growing season. However, the cooler weather also signals the arrival of seasonal pests, ready to take advantage of your organic fields. These pests tend to have an especially strong appetite for organic crops, making it essential to stay vigilant. Thus, it is important to implement appropriate IPM techniques to combat these insect pests effectively. It is crucial to plant resistant varieties, scout regularly, ensure your crops are healthy, diversify your crops, use physical/mechanical control, enhance biological control, or apply biopesticides when necessary.
Remember, some IPM tactics may be unsuitable in some situations because IPM is not a one-size-fits-all. Therefore, an IPM program should be planned on a case-by-case basis.
