# Update: Upside Robotics Slashes Corn Fertilizer and Waste
Upside Robotics is revolutionizing corn farming with its autonomous Maize Runner robots, slashing fertilizer use by up to 70% while maintaining or boosting yields and minimizing environmental waste. In groundbreaking trials across Ontario farms, these compact, AI-powered machines deliver precise, on-demand nitrogen applications, addressing soaring input costs and runoff pollution that plague modern agriculture.[1][3][4]
Breakthrough Technology Behind Maize Runner Robots
Upside Robotics' Maize Runner robots, each just 24 inches wide, navigate 30-inch corn rows autonomously using GPS and advanced sensors to monitor crop needs in real-time. Equipped with a 44-liter tank, they "spoon-feed" liquid nitrogen directly to plant roots weekly, covering one acre per hour and up to 100 acres in five days per robot.[1][2][5][6] This swarm approach—deploying 10 robots for 1,000 acres—eliminates large-scale early-season applications that lead to fertilizer loss through washing or vaporization, adapting instead to variables like temperature and rainfall via AI algorithms.[1][2][4]
Founded in Silicon Valley in 2024 and now based in Waterloo, Ontario, the company has scaled rapidly: from one remotely operated robot last year to about 20 fully autonomous units in paid trials this season across seven farms on 1,000 acres.[1][3] CEO Jana Tian emphasizes no human intervention is needed, unlike drones, which these ground-based bots outperform in cost, legality for chemicals, and crop access without trampling.[1][5]
Dramatic Reductions in Fertilizer Use and Costs
Farmers using Upside Robotics technology report cutting nitrogen applications by 30-70% without yield loss, achieving 250 bushels per acre with just 55 pounds of nitrogen—far below traditional methods.[3][4] This precision dosing saves up to $150 per acre for corn growers across soil types, tackling nitrogen as one of the largest crop input expenses.[3][4] By integrating satellite data, yield maps, and ground-level sensing, the robots ensure maximum uptake, reducing waste and enabling split applications throughout the growing season.[2][4]
The system's versatility extends to herbicides, fungicides, and micronutrients, potentially eliminating planter-side fertilizer needs and lightening equipment loads.[3][5] In 2024 trials, results drew interest from over 100 Ontario farmers and growing U.S. Midwest demand, proving commercial viability with paying customers.[2][3]
Environmental and Sustainability Wins for Farmers
Upside Robotics minimizes agricultural runoff—a leading cause of water pollution—by curbing chemical overuse and targeting delivery to roots, lowering the carbon footprint tied to fertilizer production and emissions.[2][4][6] This aligns with broader smart farming trends, where precision tech reduces fertilizer and pesticide use by over 60%, addressing labor shortages and input cost crises.[6][8]
Tanya Franklin, VP of agronomy, notes farmers gain freedom from nitrogen management, easing operational pressure while boosting efficiency on 50-100 acre fields.[3] With battery life for six hours and quick 40-minute recharges, the electric robots operate tirelessly, positioning them as a climate-friendly "upside" for growers and the planet.[2][5]
Future Expansion and Farmer Adoption
Looking ahead, Upside Robotics plans to deploy 25-50 units next year, expanding beyond corn to other crops and emphasizing spot-application as fertilization's next evolution.[2][3] Co-founder Sam Dugan highlights advantages over drones: lower costs, no crashes, and full chemical access.[1] As CEO Tian states, "I really don’t see a future for agriculture without small, autonomous robots," signaling a paradigm shift toward fully automated, data-driven farming.[1][7]
