Maristela Storti, a corn producer in Jataí, Goiás, Brazil, deployed Stenon's real-time soil analysis technology on fields planted with the high-performing Pioneer 3898 hybrid, recording a 7.98% higher yield compared to its traditional approach while reducing nitrogen input by 20%, with an estimated 0.14 tonnes/ha of CO2e emissions avoided. According to Thiago Mendonça, Stenon's Market Development Manager: "Over-fertilization doesn't guarantee better results. Applying the same rate everywhere can actually limit yield potential — oversupplying some areas while undersupplying others. This imbalance disturbs soil health, affects the plant's nutrient uptake capacity, and ultimately reduces productivity." The context was that one of the key challenges in modern corn production is balancing productivity with responsible input use, particularly nitrogen. Over-fertilization remains a widespread issue: conventional fertilization protocols tend to apply fixed, high doses of ammonium sulfate commonly seen as a "safety net" for yield, which often oversupplies nitrogen in some areas while undersupplying it in others, leading to uneven plant development and reduced yield potential. Excess nitrogen not absorbed by plants can also leach into water sources or volatilize as nitrous oxide, a greenhouse gas nearly 300 times more potent than CO2. Technically, Stenon's real-time soil analysis enables variable rate application (VRA), applying only what's needed where it's needed. The technology integrates real-time measurements, crop-specific recommendations, and structured field evaluations to enable farmers to make more informed decisions. At scale, the optimized fertilization strategy led to a profit increase of US$163.61 (R$901.50) per hectare and a total ROI boost of 17x on the trial field. Scaled across the full production area, this would represent a potential profitability gain of over US$347,673 (R$1,915,676). At the same time, smarter nitrogen management can help reduce fertilizer-related emissions by an estimated 0.14 tonnes/ha of CO2e, representing a climate value of nearly US$8 (R$45)/ha. Stenon continues to validate the benefits of precision fertilization across diverse crops and regions in Brazil, with operations in DACH, Brazil, Central Asia, Greece, and USA (California).
