Duration: From May 1, 2021 until Apr 30, 2024
Region: Long-term fertilizer experiments and experimental catchments of consortium members in Rostock and Weihenstephan, cooperation with other long-term experimental stations in Germany, own newly established pot and field experiments in Central Germany.

About the Project:

InnoSoilPhos intents to optimize the soil-P-fertility in order to lower the dependency on phosphate rock-derived P-fertilizers.

Project Aim

InnoSoilPhos intents to optimize the soil-P-fertility in order to lower the dependency on phosphate rock-derived P-fertilizers. The P use efficiency in the soil-plant-water-system will be improved by developing new technologies and pro­ducts. Furthermore, the socio-economic and political/legal frame­work will be developed.

Motivation

Phosphorus (P) is essential for all life on earth and soils are central in providing P to microorganisms and agricultural crops. While todays agriculture depends on external inputs of non-renewable mineral P fertilizers, a long-term bioeconomy strategy requires to lower the dependency on finite, rock-phosphate derived P fertilizers. A more efficient use of P in crop production is also essential for conserving or improving the freshwater quality. The research is directed to a better understanding of the P transformations across all scales from the atomic and molecular through plot/field/catchment up to the societal scale. The investigations utilize the great potential of novel physical (e.g. quantum-chemical modelling, synchrotron-based spectroscopy), chemical and micro- & molecular-biological methods.

Expected Results

New evidence in all aspects of P-speciation and P–transformations in the system soil-crops-environment will result in improved P-fertilizer recommendations, approaches to mobilize unavailable P-stocks in subsoils, application guidelines for innovative P-recycling products, novel concepts for „smart “ P-fertilizers with by-effects as well as recommendations for policy makers. InnoSoilPhos will provide the BonaRes-center with all P-specific soil data, pedotransfer functions and concepts for web-based soil-function-models.
