“Carbon management measures must have a long-term impact”

Agriculture is responsible for around 7.7% of Germany's greenhouse gas emissions. In order to achieve the climate targets, emissions of climate-damaging gases must be drastically reduced. In agriculture, this is to be achieved with the help of carbon farming. There are many measures that remove carbon dioxide from the atmosphere and store CO2 in the soil. But how does the principle work in agricultural practice and how effective are humus certificates? Carsten Paul from the Leibniz Centre for Agricultural Landscape Research (ZALF) studied this topic.

Oetker Group supports start-up incubator

Innovations in the field of life sciences secure the food production of the future and make it more sustainable. To accelerate innovation through start-ups in the fields of agriculture, food technology and biotechnology, the Technical University of Munich (TUM) and UnternehmerTUM have launched the TUM Venture Lab Food-Agro-Biotech (FAB). The Lab FAB is one of now eleven TUM Venture Labs, which are designed to support TUM researchers and students in entrepreneurial spin-offs in the various fields of technology.

“Digital systems will optimize agricultural production”

AI-supported field robots could give agriculture a significant boost toward greater sustainability. Agricultural scientist Hans G. Griepentrog is convinced of this. In recent years, the scientist from the University of Hohenheim has developed a field robot with AI-supported data analysis and intelligent sensor technology that independently makes its rounds in the fields, weeds and gives the farmer fertilizer recommendations.

 

First results on peat moss paludiculture

For decades, moors were deliberately drained for land reclamation. Only about five percent of Germany's land area is still moorland. The drainage not only destroyed the habitat of many plants and animals, but also an important CO2 reservoir. Two years ago, the federal and state governments therefore agreed to invest more than 330 million euros in projects to protect peatlands. The main focus is on the large-scale rewetting of drained peatlands. Paludiculture stands for reviving peatlands as CO2 reservoirs in a sustainable and gentle way.

Plant roots are more important for tropical soil life than assumed

Fallen leaves are an important habitat and food for millions of microorganisms. But contrary to previous assumptions, they are largely insignificant for life below the surface. An international team of researchers led by the University of Göttingen has now been able to show that the number of soil organisms depends crucially on whether there are living roots and their metabolic products.

IGZ (2023): Potential of human excrement as fertilizer

Plants need nitrogen to grow. Conventional agriculture therefore mostly relies on artificial fertilizers, which can pollute the ecosystem and the environment. In organic farming, synthetic fertilizers are prohibited. A recent study by the IGZ shows that fertilizers made from human urine produce just as good results in vegetable cultivation as established fertilizers for organic farming.

Potentials of precise plant cultivation

Field robots that weed and determine the nutrient content in the soil, or drones that detect plant diseases: modern field technology with highly sensitive sensors and cameras have already made work in agriculture more efficient and sustainable. However, the technologies used in so-called precision crop farming usually operate in isolation. Due to such isolated solutions, data is lacking and the actual benefits are difficult to evaluate. The DigiMax-PA project aims to change this.

Climate change requires breeding of new soybean varieties

Besides France, Italy, Serbia and Romania, soy is also cultivated in Germany. In the 1980s, there were just 1,000 hectares of arable land for soy; in 2022, according to the Deutschen Sojaförderring ("German Soy Promotion Ring"), there were around 51,400 hectares - an increase of almost 50% compared to the previous year. In the long term, soy production in Europe could continue to increase significantly, as more and more arable land is suitable for cultivation. This is the result of a recent study by the Leibniz Centre for Agricultural Landscape Research (ZALF).

How caterpillars deactivate the defense of cabbage plants

Plants have several protective strategies against insect pests: They can mechanically make it difficult for them to pierce or eat the leaves. They can make their taste or nutritional value unattractive. Or they can go one step further and produce substances that harm predators. But sometimes, in the course of evolution, insects fight back and bypass these defense methods. The cabbage white butterfly is a case in point.
