Abstract:
Without fertilization, the sufficient provision of crops to feed the world population would not be possible. However, fertilization in agriculture also causes negative impacts. On the one hand, this concerns the environment e.g., by infusion of nitrate into the soil and groundwater. It is a challenge to guarantee both, a sufficient fertilization of soils, and the minimization of harmful emissions. The project “StaPrax-Regio”, aims at an optimization of Nitrogen-(N)-fertilization strategies. It is well known that the interaction between weather, soil and the amount and time of fertilization are not independent from each other. Knowledge gaps still exist in a more detailed insight into the kind of interaction between the components, as well as the influence of specific parameters, such as precipitation and temperature, type, pH, cation exchange capacity of soils, and type, amount and time of fertilization. Therefore, meteorological and edaphic, as well as other factors must be taken into account when searching for a “good” fertilization practice at a specific site. Geographical Information Services (GIS) and Decision Support Systems (DSS) are adequate means to support data analysis and visualization, and finally the decision-making process on suitable fertilization strategies. The paper presents work-in-progress within the framework of a transdisciplinary research project of partners from industry, weather and geological services, and science.
