Abstract
Der Vortrag zieht die Bilanz aus dem humanwissenschaftlichen Teil der Arbeit des Phosphor-Campus, der sich vor allem mit wirksamen politisch-rechtlichen Instrumenten beschäftigte, die auf eine stärkere Kreislaufführung und geringere Umweltbelastung bezogen auf P abzielen. Die vom Referenten geleitete Forschungsstelle Nachhaltigkeit und Klimapolitik hat entsprechende Instrumente seit 2013 geprüft und neue Steuerungsansätze entwickelt. Leitend war dabei die Erkenntnis, dass eine selektive P-Governance kaum entwickelt werden kann. Vielmehr muss es um Instrumente der Landnutzungs-Governance zur integrierten Lösung verschiedener untrennbar verbundener Umweltprobleme gehen (wie Klimawandel, Biodiversitätsverlust, gestörte Nährstoffkreisläufe u.a.m.). Als besonders zentral erwiesen sich dabei ökonomische Instrumente, die auf eine Mengensteuerung der Tierhaltung sowie der fossilen Brennstoffe abzielen, flankiert durch Ordnungsrecht und Subventionen, wobei letztere allerdings einen grundlegenden Umbau erfordern und auch nicht – wie bislang – als Haupt-Steuerungsinstrument im Agrarbereich taugen.

Abstract
Rapeseed is an economically and soil-ecologically valuable crop in crop rotations, but has a high P requirement. For the vast majority of all plant species, the essential factor for improved P supply is symbiosis with fungi, mycorrhiza formation. However, rapeseed is one of the few non-mycorrhizal crops, so its root growth is of increased importance for P supply. Organic fertilization and biostimulants can significantly promote root growth and thereby contribute to increased P use efficiency. As part of improved nutrient recycling, the potential of mushroom compost and marine biomass for fertilizing rapeseed was tested. The potential of organic fertilization and biostimulants to promote root growth and yield of rapeseed was revealed in pot experiments and initial field trials and is currently being tested in several field trials in a research network.

Abstract
The current understanding of the sources, transport paths and inputs of phosphorus into the waters of Mecklenburg-Vorpommern is the subject of the presentation. Our monitoring shows that the legally binding target values for rivers, lakes and coastal waters, as well as for groundwater, are often exceeded. Nutrient models are used to determine the causes and to develop measures. Detailed information are available for the point sources from wastewater treatments plants / municipal sources, which account for approx. 34% of the inputs. For the diffuse sources, considerable inputs are groundwater inflow (32%), direct atmospheric deposition onto water surfaces (10%), drainage (5%) and erosion (5%). More than half of all river monitoring stations exhibits concentrations above the target value for total phosphorus, with almost a third above the target value for phosphate. All coastal waters of Mecklenburg-Vorpommern are impacted by phosphorus inputs in a way that prevents them from achieving the good status of the Water Framework Directive. Furthermore, 55% of the groundwater waterbodies (28 of 51) are failing to achieve good chemical status due to phosphate exceedances. There remain many open questions about the causes and processes of the diffuse phosphorus inputs, such as background values, soil and hydrogeological processes, leaching and the behaviour of the different phosphorous compounds / fractions.

Abstract
Under natural conditions, crops interact with a variety of microorganisms. These include beneficial (symbiotic) and phytopathogenic microorganisms, which together affect plant growth and productivity. In recent decades, potato (Solanum tuberosum L.) production has been decreasing due to the prevalence of potato virus Y (PVY), which is one of the most important pests of the potato. Arbuscular mycorrhizal fungi (AMF) are common symbionts of potato, but the effect of mycorrhizal symbiosis on PVY disease development is poorly understood. Within the framework of two research projects on this issue, the effects of different AMFs on healthy and virus Y (PVY) infected potato were investigated. The analyses carried out included not only the measurement of potato growth parameters, but also indicators of oxidative stress and photosynthetic capacity. In addition, the development of AMF in plant roots was assessed, as well as the level of the virus in mycorrhizal plants. Studies have shown that there are multifactorial interactions in host plants colonized by phytopathogens and endophytes that are important for potato cultivation in agriculture.

Abstract
Land plants produce a variety of sugars, but an excess of galactose leads to severe symptoms of poisoning. However, the underlying mechanisms are still poorly understood. In mammals and fungi, galactose is enzymatically converted into uridine diphosphate galactose and glucose-1-phosphate. If the enzymes involved do not work correctly, galactosemia occurs - a severe metabolic disorder. In patients with galactosemia, it is assumed that the accumulation of the intermediate degradation product galactose-1-phosphate triggers the disorder. Land plants use a modified degradation pathway for galactose, in which the UDP-sugar pyrophosphorylase is of central importance. However, we were able to show that its increased activity and the associated reduction of galactose-1-phosphate even leads to an aggravation of the symptoms of poisoning in plants. Our analyses of the activated form of galactose - uridine diphosphate galactose - rather suggest that its increase is a major cause of galactose poisoning, as this leads to disturbances in cell wall synthesis. The lecture will also discuss other poisoning effects.

Abstract
More and more peatlands are becoming of interest to science and society because of their contribution to greenhouse gas emissions and, thus, to global climate change. The function of peat soils in the water and nutrient cycles is, likewise, assumed to be substantial but far less studied. Peat soils, especially in a pristine state, are unique in the sense that their hydro-physical properties differ often dramatically from those of mineral soils. The most extraordinary feature of peat is its high porosity, which easily exceeds 90 vol% with a dominance of macropores (>50 μm). Drainage of peatland accelerates carbon mineralization, resulting in a higher bulk density and a lower porosity. This conversion of the peat goes along with a shift in hydraulic properties and, thus, in the functioning of the peatland in the landscape, although almost no study has ever quantified the impact of peat soil degradation on water and solute movement at the landscape level. It remains a challenge to assess as to what extent degraded fen peats are connected to adjacent mineral soils and water bodies
