Our main mission is to develop models and DSS on the basis of existing and newly generated knowledge that allow resource-saving production and at the same time can be adapted to changing climate conditions. Efficient production of high-quality vegetables in rural areas will only be possible if the available resources are used responsibly and losses to the environment are avoided.

The pre-requisite for such outdoor production is deep understanding of soil and climate conditions, the plant requirements at the various stages of development, and the interaction of these factors. Much of this knowledge has already been generated under current climatic conditions, but the quantification and in particular knowledge application in production is often very patchy. Knowledge transfer can be done through systems modelling and DSS. As the knowledge about nutrient demand of the plants in every growth state of vegetables is very important, we focus on the creation of knowledge based systems using sensors and models. Thus, we model the nutrient cycle of the soil and combine calculated and measured data. With this combination, we focus on the definition of future management strategies to improve the productivity of soils used for horticultural purposes.
