OnFarm Weather
The aim of the project is the development of an online tool that for the first time enables farmers to make decisions based on local weather information in Schleswig-Holstein. With more accurate weather data characterizing the field-specific situation, farmers can e.g. optimize fertilization and crop protection according to the latest findings. Based on an existing prototype, the OG wants to test and develop a system for recording local weather.
With the testing on practice farms practical questions are worked on, such as e.g. requirements for site, instrumentation and maintenance, as well as the comparison of locally collected weather data with reference weather. The findings form fundamentals e.g. for the optimization of fertilization, plant and water protection. The results serve as a recommendation for a uniform standard that integrates data from private weather stations into the nationwide agrometeorological monitoring network. This will create the conditions for a regional demonstration measurement network.
It was shown that the concept of redundant measurement at one location is suitable for recognising measurement errors and increasing reliability. This makes maintenance more targeted and cost-effective. It also effectively prevents incorrect measurements from entering the database.
In addition to the measured values from the stations, derived values are also provided with daily resolution. These variables were calculated on the basis of local weather data. A simulation model was developed for this purpose, which calculates the potential evapo-transpiration under grass according to FAO standards. The soil water balance is simulated for different soil layers based on DSSAT 4.0. The soil temperatures are calculated analogue to the EPIC model. The influence of snow cover on percolation and evaporation is simulated based on the Daisy model from Denmark.
