• Josef Hauser: "Development of stable yield forecasts using artificial neural networks for the economic optimization of site-specific nitrogen fertilization in winter wheat" (Agricultural Management)

Short description: Site-specific cultivation generates enormous amounts of data with corresponding utilization potential. The use of data mining in precision agriculture could prove to be a practicable tool. Especially for the planning of site-specific nitrogen fertilizer application, small-scale yield forecasts have been created for years with the help of data mining tools in order to calculate economically optimal nitrogen applications on a site-specific basis.

Bachelor and Master theses

• Antonia Modersohn (2023): "The CO2 footprint of one liter of milk" (Master thesis)

Short description: The topic of the thesis is to determine the CO2 footprint of one liter of milk as produced on the Pfaffendorf farm. The years 2017-2021 are compared with each other. In 2018, the conversion from conventional farming to organic farming in accordance with EU regulations took place and in 2020 production was converted to organic farming. The aim of the work is to determine how the different production conditions and requirements imposed by the labels (use of fertilizers, feed purchase, feeding) affect the carbon balance of the milk. Furthermore, there is the possibility to look at the years 2018 and 2019 as dry years in the region of Central Germany and to see how a reduced feed production on the farm as a result of climatic extremes can affect the carbon footprint.

• Sophie Henninger (2023): "The influence of biostimulants on yield and vitality in alfalfa in organic farming" (Bachelor thesis)

The aim of the trial in 2023, which was set up on practice areas of the  Teaching and Experimental Station Görzig, was to use biostimulants to increase the yield of alfalfa and strengthen its vitality, especially under drought stress. The two biostimulants tested were the product "Oceryos III" from the company "TimacAgro" and "BlackHum" from the company "PHYTOsolution. For further information, see "Current research (Field 350)".
