Main objective:

The main objective of GrasSat project is a fully operational system in form of desktop and mobile application, which provides a complementary tool for managing grassland production, mainly for medium and large farms in Poland and Norway. Combining the effectiveness of the application with the support of external advisors is the key to improve grass production management. Experience of the team of remote sensing and grassland specialists will be the firm foundation of the tools to be prepared within the project.

Specific objectives:

The project objectives were defined as follows:

  • delivery of the service in the form of desktop and mobile application to optimize farm management like reducing the need for supplementary forage;
  • development of the method for grassland damage assessment, caused by drought or winterkill on the basis of multi-source satellite data and their synergy with meteorological data;
  • novel approaches will be generally based on innovative use of satellite data in the grassland management to increase yield and monitoring of grassland status.

Methodology:

The methodology for monitoring grass growth conditions and yield forecast will be based on synergistic use of remotely sensed data, process-based grassland models and reference in-situ data, indispensable for elaborating reliable models characterizing plant development. Using remote sensing to etimate the expected yield in a grassland can help farmers to prepare for importing forage and to detect areas with high water stress. In addition, process-based models can help estimate the impact of a drought of freezinf event on the yield. The project assumes the use of ground data for the calibration of satellite data.
