Gasser S., Nielsen K., Eichler‐Löbermann B., Armbruster M., Merbach I., Franko U. (2023). Simulating the soil phosphorus dynamics of four long‐term field experiments with a novel phosphorus model. Soil Use and Management, (), . doi:10.1111/sum.12881

Phosphorus is a nonrenewable resource, which is required for crop growth and to maintain high yields. The soil P cycle is very complex, and new model approaches can lead to a better understanding of those processes and further guide to research gaps. The objective of this study was to present a P-su…

The eutrophication of the Baltic Sea is a longstanding environmental issue which is caused by excessive nutrient input including phosphorus. In response, neighbouring states of the Baltic Sea adopted the Helsinki Convention and the updated Baltic Sea Action Plan. The Helsinki Convention aims at the …

An assessment of CAP subsidies for precision fertilization and sustainable agricultural practices in Germany. Frontiers in Sustainable Food Systems, 7(), . doi:10.3389/fsufs.2023.1088640

The Farm to Fork Strategy of the EU aims at sustainable food systems. One objective of the Strategy is to reduce nutrient losses by at least 50% resulting in at least 20% less fertilizer use by 2030. To this end, Member States are expected to extend digital precision fertilization and sustainable ag…

The agronomic value of fertilizer phosphorus (P) in the soil is determined by how it is incorporated and released during aggregate formation and breakdown. These processes play a vital role in P accessibility, storage, and cycling. Bone char (BC) is a promising substitute for phosphorus fertilizer. …

Koch S., Rosewig E., Lennartz B. (2023). Legacy Phosphorus in Sediments of Lowland Waterways. Environments, 10(3), 43. doi:10.3390/environments10030043

Riverbed sediments in agricultural landscapes are loaded with phosphorus (P). They may act as a source or sink for riverine P, possibly causing harmful algae blooms and eutrophication in streams and receiving water bodies, including coastal waters. In this study, we aimed at identifying the labile, …

Abstract Subsurface losses of colloidal and truly dissolved phosphorus (P) from arable land can cause ecological damage to surface water. To gain deeper knowledge about subsurface particulate P transport from inland sources to brooks, we studied an artificially drained lowland catchment (1550 ha) in…

Subsurface losses of colloidal and truly dissolved phosphorus (P) from arable land can cause ecological damage to surface water. To gain deeper knowledge about subsurface particulate P transport from inland sources to brooks, we studied an artificially drained lowland catchment (1550 ha) in north-ea…

Chiba A., Peine M., Kublik S., Baum C., Schloter M., Schulz S. (2022). Complete Genome Sequence of Psychrobacillus sp. Strain INOP01, a Phosphate-Solubilizing Bacterium Isolated from an Agricultural Soil in Germany. Microbiology Resource Announcements, 11(4), . doi:10.1128/mra.00207-22

We report the complete genome sequence of the phosphate-solubilizing bacterium Psychrobacillus sp. strain INOP01, isolated from an agricultural field in Rostock, Germany. In addition to its phosphate-solubilizing ability, the genome contains genes coding for proteins involved in phosphate (P) acquis…

AbstractBone char (BC) is a promising P-recycling fertilizer but with rather low P-solubility, which can be increased by modifying the BC surface with elemental sulfur (BCplus), but effects on the soil P status have not been tested under field conditions yet. Hence, a long-time field experiment was …

Thresholds of target phosphorus fertility classes in European fertilizer recommendations in relation to critical soil test phosphorus values derived from the analysis of 55 European long-term field experiments. Agriculture, Ecosystems & Environment, 332(), 107926. doi:10.1016/j.agee.2022.107926

Phosphorus (P) fertilizer recommendations of individual countries may differ in many aspects, but often the main principle is to reach or maintain a target range of plant-available P in soil. Within this target P fertility class, the soil is expected to supply enough P to the crop, while P fertiliza…
