The phosphorus content in Mühlviertel soils is very low, and hardly plant-available. In the project, crops are cultivated that can make phosphorus plant-available through root exudates and symbioses with mycorrhizae. Various crops are cultivated on different farms. During the growing season, plant samples are collected and analyzed for various trace elements. Soil samples are taken before planting the test plots and after harvesting the main crops, analyzed by AGES using the Schaller P-release rate method. In addition to crop trials, fertilization experiments are also conducted.
The project aims to identify measures that mobilize phosphorus bound in the soil. By selecting optimal plant associations, fertilizer use can be reduced. Knowledge transfer is facilitated through a "Phosphorus Guide" and a learning module on "Phosphorus in Soil".
