The April 2026 release reworks how fertilizer application amounts are recorded and displayed — moving from a single kg/ha convention to fertilizer-native units — and introduces a new Mineralisatie Labs feature backed by a Mineralization module in fdm-calculator. RVO field import becomes available to all users, the Atlas gains an advanced cultivation history view, and Gerrit receives a crop-specific preferences skill and a field-level plan explanation. The release also includes a number of performance, reliability, and tooling improvements that have been published as hotfixes since the previous release.

The March 2026 release introduces two new packages — fdm-rvo for connecting to the Dutch RVO agricultural registry and fdm-agents with an AI-assisted fertilizer planning tool in Labs — alongside a substantial rework of the fertilizer management interface, organization-level balance visualizations, and several data quality corrections in the fertilizer catalogue.

The February 2026 release brings three major workflow improvements: uploading and reviewing multiple soil analyses in one go, editing harvest data and fertilizer applications directly from the rotation table, and a new invitation system that allows non-registered users to be invited to a farm before they sign up. The release also adds a carbon sequestration card to the Atlas and two new SOM-based calculator functions.

The January 2026 release includes buffer strip support, updated grassland regulation logic, and the new "Bemestingsplan" PDF export. Key changes also include the integration of the BRO Soil Map and a refactor of the balance calculation engine to support field-level caching.

As we approach the end of the year, the December release of the Farm Data Model (FDM) focuses on looking ahead to 2026 while refining the tools you use today. We have upgraded our Nitrogen Balance insights with deeper breakdowns and integrated high-resolution AHN4 elevation data into the Atlas. Additionally, we've introduced initial support for the 2026 Dutch fertilizer application norms, acting as a placeholder while final political decisions are still pending. Under the hood, we've improved type safety across our packages and streamlined the authentication experience.

This November release marks a major expansion of the Farm Data Model (FDM) capabilities. We are introducing a brand-new Organic Matter Balance module, completing the Nitrogen Balance with Nitrate Leaching insights, significantly upgrading Harvest analysis with crop-specific parameters, and streamlining crop management with the new Rotation Page. Alongside these agronomic leaps, we've revamped our documentation and refined the user interface with better map controls and a sharper sidebar.
