Nitrogen Content Control in Potatoes Using Satellite Technologies

Swedish AgTech company Vultus presented a new satellite analysis technology for measuring nitrogen content in potato leaves on March 13, 2025, which could significantly change approaches to yield forecasting and precision fertilization. Nitrogen is a critically important element for potato growth, as it affects yield, tuber quality, and the overall health of the plants. However, optimal nitrogen use has always posed a challenge for farmers: insufficient application delays growth, while excess can lead to financial losses and negative environmental impacts.

Vultus, led by CEO Per Karlsson, offers an innovative solution based on artificial intelligence and Sentinel-2 satellite data. Unlike traditional methods that require labor-intensive sampling, their system provides real-time nitrogen analysis across the entire field area. This allows farmers to accurately determine plant needs and avoid mistakes in fertilizer application. After four years of development, including field trials and improvements to machine learning models in collaboration with Lyckeby AB, Vultus launched a full-service solution that can predict yield and optimize nitrogen use just 60 days after planting.

“Excess nitrogen often does more harm than good,” Karlsson noted. “It promotes leaf growth instead of tubers, reduces quality, and contaminates groundwater.”

A lack of nitrogen, on the other hand, reduces leaf area and photosynthesis, leading to fewer tubers and decreased yields. Vultus technology addresses these issues by analyzing chlorophyll, canopy structure, and water content, which correlate with nitrogen levels. Additionally, the system predicts yield based on biomass, helping farmers plan logistics more effectively and secure contracts.

The service is available through a web platform and integrates with existing farm systems.
