P-Campus Lecture Series 2024
THURSDAYS | ONLINE VIA WEBEX
In March 2024, the new multidisciplinary lecture series of the ScienceCampus Phosphorus Research Rostock will start. Look forward with us to exciting lectures from different disciplines and use the lectures for professional exchange.
The lectures are open to everyone after registration. The presentations will be given in German or English (see respective lecture for details). Questions to the lecturer may be in German or English.
After your registration you will receive a confirmation e-mail. The access data will be sent to you on the day of the event.
The lectures will be recorded and made available to P-Campus members and registered participants upon request.
Please make sure that Webex has access to your speaker (test here in advance). If you have any questions about this, please contact Maxi Hoche (maxi.hoche@catalysis.de). If you have any subject-specific questions concerning the lectures, please contact Dana Zimmer (dana.zimmer@catalysis.de). We look forward to your participation and exciting discussions.
Lectures
Legumes have a high demand for phosphorus (P) due to the energetically costly biological nitrogen fixation, but they also have effective physiological and morphological strategies for P mobilization. To evaluate the inter- and intraspecific P efficiency of small-grain legumes under contrasting long-term P management, eight accessions each of alfalfa (Medicago sativa L.) and red clover (Trifolium pratense L.) were cultivated in two consecutive growing periods from 2020 to 2021 in a field trial established in 1998. In 2021 and 2022, same accessions of both species were also cultivated in two pot experiments under greenhouse conditions to further evaluate their P efficiencies of utilizing different P recycling products. This study underscores the high potential of P mobilization of small-grain legumes without pronounced inter- or intraspecific differences. While struvite is suitable as a P fertilizer, the application of sewage sludge ash to legumes is not recommended.

Abstract
In fact, the world is facing a triple crisis: accelerating climate change, loss of biodiversity and pollution. With regard to the latter, the number and quantity of chemicals and anthropogenic particles produced, used in agriculture and industry and emitted into the environment are increasing, acting as single pollutants or as complex mixtures that are difficult to detect and even more difficult to regulate. This pollution threat is exacerbated by climate change and endangers biodiversity in terrestrial and aquatic ecosystems as well as human health. All this contrasts the EU's Zero Pollution Plan, which aims for a toxic-free environment by 2050 at the latest and pollution levels no longer considered harmful to ecosystems and human health.
This presentation will highlight the most relevant and stressful pollutants for the environment, such as phosphorus, microplastics and highly persistent 'forever' chemicals such as PFAS. After presenting this as an overarching area of concern, initial possible solutions to overcome the pollution crisis in line with climate and biodiversity targets will be discussed.

Abstract
Lysimeters have proved to be particularly suitable for the determination of soil water balance parameters and for the study of water and solute fluxes in soils. Based on the definition of the term, various constructive solutions for the construction and operation of lysimeters and the resulting consequences for the investigation of the water and solute fluxes in soils are presented. Differences with regard to filling (disturbed or undisturbed), weighing (weightable or non-weightable), size (lysimeter surface and depth) and construction of the lower boundary condition (free drainage or drainage by applying a controlled negative pressure) are discussed in detail. Typical applications in environmental monitoring and research are shown and advantages and disadvantages of current lysimeter systems are discussed.

Abstract
Hydrophysical, chemical and biological parameters have been investigated at the Biological Station Zingst for over 50 years. Initially, weekly samples were taken and daily measurements were taken for many parameters, including the freely available nutrients, from 1980 onwards.
The reduction in nutrient inputs since the 1990s did not lead to improvements in eutrophication levels for a very long time. The maximum values of free nutrients have been decreasing since 1990: Nitrate from 600 µmol l-1 to approx. 200 µmol l-1. The phosphate peaks of up to 10 µmol l-1 now fell to a few short events, e.g. under ice cover lasting several weeks. Phytoplankton, turbidity and seston remained unchanged.
For the past 3-4 years, however, the depth of visibility has improved significantly, especially in late summer and fall, from an average of approx. 40 cm without clear maximum values of approx. 10 cm with numerous observations of 1-3 m. This was accompanied by a decrease in chlorophyll biomass from summer onwards. Whether this change is related to hydrological conditions is currently being investigated.
