Key Takeaways
- OneSoil, a Zurich-based precision agtech company, has partnered with Polish climate tech startup Rainbow Weather to add a Hyperlocal Precipitation Forecast feature to its farming platform.
- The feature predicts rainfall probability and intensity down to a four-hour window for exact field coordinates, using machine learning models trained on radar, satellite, and atmospheric data.
- The integration has already been used by more than 15,000 farmers monthly since launch.
- Extreme weather costs EU farmers approximately €28 billion per year, around 6% of total agricultural production, providing the commercial backdrop for the partnership.
- OneSoil's platform serves over 1.16 million users across Europe, Latin America, the US, Africa, and Australia, with enterprise clients including Corteva and BASF.
OneSoil Adds Hyperlocal Rainfall Forecasting to Its Precision Agriculture Platform
OneSoil, a Zurich-based agtech company specialising in AI-driven precision agriculture, has formed a partnership with Rainbow Weather, a Polish climate tech startup, to integrate hyperlocal precipitation forecasting into the OneSoil platform. The collaboration, announced on June 4, 2026, responds to a growing operational problem for farmers: the increasing frequency and unpredictability of extreme rainfall events, which have accelerated since the early 2000s and now cost EU farmers an estimated €28 billion annually, equivalent to roughly 6% of total agricultural production.
OneSoil's existing app already provided farmers with access to wind speed and temperature data via a Virtual Weather Station feature. The new Hyperlocal Precipitation Forecast layer adds cloud motion tracking and short-range rainfall prediction, delivering forecasts down to a specific four-hour window for any precise set of field coordinates — from a sunflower plot in France to a cornfield in South Africa. The feature is part of OneSoil's broader push to expand the precision agriculture tools available to growers managing field operations under variable weather conditions.
How the Technology Works
Rainbow Weather's forecasting capability is built on machine learning models trained to process large volumes of radar, satellite, and atmospheric data, identifying patterns in how precipitation develops and moves across a region. This approach enables ultra-short-range predictions that go beyond what standard daily or hourly weather services provide.
Alexander Matveenko, co-founder and CEO at Rainbow Weather, highlighted the shift in how farmers are experiencing climate risk:
“Over the last few years, weather has become one of the biggest sources of risk in agriculture. In these conditions, farmers are looking for tools that could help them access granular data on upcoming precipitation, as well as historical data on how much rainfall has already occurred, so they can better plan fieldwork. Rainbow Weather is exactly what they need,” said Alexander Matveenko, co-founder and CEO of Rainbow Weather.
Why Near-Term Forecasting Matters for Farm Operations
For OneSoil, the value of the integration lies in the financial consequences of unexpected rain during field operations. Fertilising and chemical spraying are particularly sensitive to timing: if rain falls immediately after a treatment pass, the applied inputs can wash away, forcing re-application, wasting labour, and causing soil compaction from additional tractor runs.
“Knowing what will happen in the next few hours is more valuable than a general daily forecast,” said Stepan Zulynskyi, CEO of OneSoil, explaining that thousands of dollars in crop inputs can be lost in a single unexpected downpour, making short-horizon AI-powered farm intelligence a direct financial tool rather than just an informational one.
The feature has been taken up by more than 15,000 farmers per month since its introduction. OneSoil's platform currently serves more than 1.16 million users globally, with approximately 140,000 annually active farmers across Europe, Latin America, the US, Africa, and Australia. Enterprise clients using the platform include Corteva and BASF, positioning OneSoil within the broader agtech sector's shift toward climate-resilient farming tools.
