A GEO-based digital calendar for real time and site specific registration of grassland management

In the Netherlands, grassland management is typically registered on a grassland calendar. The last years digital versions of the grassland calendar became available. The major challenge is to register dynamic use of paddocks during a growing season. Combining registered grassland management with geosynchronous equatorial orbit (GEO) data, e.g. data from satellites and machines is, however, difficult. To overcome these issues a digital grassland calendar was developed based upon GEO data. Polygons are used to define the paddock (or part of ) for which management is registered. These polygons can be created at any moment during the growing season, which makes it possible to dynamically register management in parts of the paddock. The Grassland Calendar is a registration tool, providing an overview of the registered data with the traditional calendar view. Since it is a digital web-based calendar, registrations are digitally available and can be shared with others. Furthermore, the data can be used in other applications and advice models. The Grassland Calendar is available at the data service platform Farmmaps (https://www.farmmaps.net/en). The Grassland Calendar is developed in cooperation with farmers and private companies in the projects ‘Precisielandbouw 4.0’ and ‘Netwerk Praktijkbedrijven’ which are financially supported by the Dutch Ministry of Agriculture.
