High-resolution meteorological data is of key relevance for agriculture since weather plays an important role in agriculture. It has a substantial influence on crop growth and yield development, incidence of pests and diseases and irrigation requirements. Weather forecast can significantly support the decisions made on optimization of agro-management practices, such as fertilizer applications and cultural field operations. The Balkan area/South-eastern Europe has an intensive agricultural production and plays an important role as well in European agricultural space. Agricultural sector is big water user in many countries in the area and proper irrigation scheduling (applying of water when needed in the optimal amount) is necessary. Optimization of irrigation water use is based on the fact that sensitivity of crop growth and development may vary between different stages of crop growth. We propose two applications with associated smartphone application (or at least web page adjusted to smartphone): Weather forecast for agriculture application and Irrigation advice application. As we already explained good weather forecasts are extremely important in agriculture, thus we propose application for high resolution weather forecast with the lead time of 3-4 days, which will provide crucial agro-meteorological variables used in agriculture on hourly basis and especially focus on the rain. The spatial extent covers broader Balkan region. Moreover, data from this application could be used also used as an input for other application (e.g. irrigation). Irrigation advice application is a simple application for advising on irrigation timing and amount of water applied for major crops, based on farmers’ tensiometer/lizimeter measurement and rain forecast from Weather forecast for agriculture application. The application will be structured in a simplified manner, offering a farmer a real-time information on the amount of water needs for irrigation.
