Phosphorus (P) is an indispensable element to all forms of life and its efficient use in fertilizers is one of the conditions for food security. The efficiency of P fertilizers is affected by P mobilization and P fixation, both depending on the P binding strength to soil constituents. This review pr…

AbstractHeterogeneous flow pathways through the soil determine the transport of dissolved and particle-bound nutritional elements like phosphorus (P) to ground and surface waters. This study was designed to understand the spatial patterns of P in agriculturally used soils and the mechanisms causing …

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. …

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…

Koch S., Rosewig E., Lennartz B. (2023.0). 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, …

Gasser S., Nielsen K., Eichler‐Löbermann B., Armbruster M., Merbach I., Franko U. (2023.0). 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…

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 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 …

Machine learning and computational chemistry to improve biochar fertilizers: a review. Environmental Chemistry Letters, 21(6), 3159-3244. doi:10.1007/s10311-023-01631-0

AbstractTraditional fertilizers are highly inefficient, with a major loss of nutrients and associated pollution. Alternatively, biochar loaded with phosphorous is a sustainable fertilizer that improves soil structure, stores carbon in soils, and provides plant nutrients in the long run, yet most bio…
