Science Slam-Talks

The Science Slam-Talks – “Science Slam-Talks im Wissenschaftsjahr 2020/21 – Bioökonomie” – is a project founded by the BMBF to clear up prejudices and to transfer knowledge in the field of bio-economics to a broader audience. During the presentation Dr. Doreen Babin explains how microorganisms form the soil memory and thereby contribute to a healthy soil. In an easy-to-follow and entertaining way she gives insights into recent methodologies and experiments from DiControl. The talk is followed by questions and discussions how this knowledge can contribute to a sustainable agriculture.

Conventional agricultural practices based mainly on the input of synthetic fertilizer and pesticides which have increased productivity, but has resulted in a number of negative impact on soil functioning and quality. Nearly all relevant soil processes are microbe-mediated and are key factors for soil functions and plant productivity. A better understanding of soil-plant-microbe interactions in agroecosystems may pave the way towards a more sustainable agriculture. We therefore aimed to study the effect of different long-term farming practices on the soil and rhizosphere microbiota as well as plant performance (growth, health, root exudates). A long-term field experiment in Bernburg (Germany, 1992) served as study site, which allows comparing of two soil management practices (mould-board plough vs. cultivator tillage) as well as nitrogen fertilization intensities (intensive fertilization including fungicides vs. reduced extensive fertilization without fungicides). Soil samples were collected from the different treatments and the model plant lettuce (Lactuca sativa, L. cv. Tizian) cultivated in the respective soil samples for 10 weeks under controlled climate chamber conditions. High-throughput sequencing of bacterial 16S rRNA genes or fungal ITS fragments, respectively, PCR- amplified from total community DNA of rhizosphere and soil samples showed significant differences in microbial community compositions depending on the long-term farming practices. Moreover, differences depending on long-term agricultural management in plant growth and health as measured by RT-qPCR of stress-related plant genes were observed. Quantity and quality of lettuce root exudates differed among the soil treatments and indicated different stress potentials of farming practices on plants. Under controlled growth chamber conditions, we could show that the lettuce rhizosphere microbiota assemblage as well as plant growth and health are significantly influenced by farming practices. We suggest a farming-dependent legacy on the performance of the subsequent crop generation via belowground plant-microbiota interactions.

INIA-JKI organized Workshop in Montevideo

From the 14th to 16th of November 2019 the JKI and its Uruguayan partner INIA (Instituto Nacional de Investigación Agropecuaria) organized an international workshop at Montevideo/Uruguay adjacent to the REDBIO conference. Here the role of soil microbiomes in agro-ecosystems for soil and plant health and the potential for development of more sustainable farming practices were discussed. Unique opportunity were offered to initiate bilateral projects aiming at developing a hypothesis-driven research frameworks. The aim is to better understand the mechanistic effects of agricultural management practices on soil microbiomes and interrelations in agricultural soils residing in different geographic and climatic zones.
