Making use of the plant's defences

Last summer, heat and drought have afflicted farmers in many places and caused enormous harvest losses. The damage caused to farmers in Germany was estimated by the Federal Ministry of Food and Agriculture at 770 million euros.
Extreme weather conditions make plants more susceptible to disease and pest infestation. This also endangers wheat production in Germany and large parts of Europe.

Fertilizer

Vital element

Phosphorus is essential not only for plants, but also for humans. An adult human needs about 0.8 grams of the mineral per day, but consumes up to 3 grams per day through food. Excess phosphate compounds are excreted by the kidneys. In this way, large quantities of phosphorus-containing waste water reach the sewage treatment plants every day.

Farming in the digital age

The profession of farming has a long tradition in Robert Hagemann’s family. Without the German reunification, however, it is unlikely that the native of Lower Saxony would have followed in the footsteps of his grandfather and father. In 1990, the family of the then 15-year-old Robert Hagemann moved to the region of Prignitz, where they established an agricultural business in Groß Pankow, far from his old home. “My father had always dreamed of having his own large company.

Compostable coffee capsules

For much of his career, Florian Hammerstein wanted nothing to do with coffee. The market is too closed off, the structures too immobile, and only a few high-ranking players have a real say in the future of the industry. It is thanks to his enthusiasm and courage to pursue unusual projects that Hammerstein and his company, Original Food, remain actively involved in the coffee business.

Dodder does more than feed off plants

Few organisms can survive on their own, many live in symbiosis with others, some of which are parasitic. Dodder, a parasitic vine of the genus Cuscuta, grows rapidly, entwining and parasitizing its host plants by inserting haustoria (a special organ that only parasitic plants have that functions analogue to roots) into the host plants’ stems. The dodder vines often connect different host plants together and form a network.

Coffee cup

From old to new

Transforming old coffee into new products - that is the idea behind the products of the Berlin start-up Kafform. On offer: coffee cups and saucers, that consist of 40% recycled coffee grounds. Each cup is made of 60 grams of coffee grounds, which is equivalent to eight cups of coffee. Other ingredients are plant fibers and a resin made of biopolymers.

3D structure of a fertilizer producing enzyme

The vanadium-dependent nitrogenase is an enzyme that catalyses two important processes: On the one hand it converts atmospheric nitrogen (N2) to ammonia, on the other hand it reduces carbon monoxide (CO) to hydrocarbons. Today, both reactions are run on a big scale by chemical catalyses to produce ammonia and fuels for industry. In additon, ammonia is used as synthetic fertilizer to ensure the food production for at least half of the world’s population.
