Producing sufficient food, feed, fiber, and fuel for our world population while simultaneously reducing the environmental footprint of agricultural production is a great challenge for humanity. DigiCrop.Net is a new platform of four leading research organizations from across the world who aim at supporting this endeavor with technology-driven approaches as key elements of possible solutions. Together, the partners seek to address central challenges and investigate novel ways for achieving sustainable crop production.

Farmers usually plant so-called cover crops after harvesting their main crop in the Fall. This prevents erosion of the soil and nutrient leaching. The roots of these crops also stabilize the structure of the soil. It had been assumed up to now that a mixture of different cover crops would result in particularly intensive rooting. However, a recent study carried out by the University of Bonn, University of Kassel and University of Göttingen found only limited evidence that this is the case. Instead, mixed cover crops grow thinner roots than when just one single type of cover crop is planted. This result was unexpected. It documents how little is currently understood about the interactions between plant roots. The study was published in the magazine “Plant and Soil.”

The 5th INRES - Minisymposium (INRES Day) will take place on August 24 on the Campus Poppelsdorf in the lecture hall center "CP1-HSZ", Endenicher Allee 19C, 53115 Bonn, Germany.

Gases that are harmful to health and the climate are produced wherever livestock are kept. Although there are various ways of supposedly reducing these emissions, it is often impossible to say with any certainty how effective they are. This is because recording precise levels of harmful gases has so far been a laborious, costly and time-consuming process. A Germany-wide joint project is now setting out to change that with the help of more than €10,5 million in funding from the Federal Ministry of Food and Agriculture. The official funding certificate has been presented yesterday by Agriculture Minister Cem Özdemir at a ceremony in Potsdam. Among other things, the methods being developed are intended to identify particularly efficient ways of reducing emissions.

At the career fair organized by the Cluster of Excellence PhenoRob together with the Faculty of Agriculture and the Theodor Brinkmann Foundation students, PhD students and graduates of the University of Bonn were able to expand their professional network and make new contacts.

Nitrogen as a fertilizer can increase yields. However, too much nitrogen can also have negative effects, such as groundwater pollution, high energy consumption in fertilizer production and the generation of climate-relevant gases. Science is therefore looking for ways to help crops thrive with less nitrogen. Researchers at the University of Bonn have discovered gene variants of the nitrate sensor NPF2.12 that trigger a signal cascade chain at low soil nitrogen levels. This induces stronger root growth, resulting in improved nitrogen utilization. The study had already been published online in advance in "New Phytologist." The final version has now been published.

Students and graduates of the University of Bonn are welcome to participate in the first PhenoRob Career Fair to expand their professional network.

Livestock farming produces large quantities of greenhouse gases, especially methane, which is particularly harmful to the climate. Among other things, it escapes during the storage of animal excrement, the slurry. A study by the University of Bonn now shows that methane emissions can be reduced by 99 percent through simple and inexpensive means. The method could make an important contribution to the fight against climate change. The results have now been published in the journal Waste Management.
