AbstractThis course is about the physical, chemical, and biological processes in the rhizosphere and their effect on plant growth. Effects of fertilisers, companion plants, and microbial symbionts, and other microbes on nutrient cycling and plant uptake are discussed. An "intercropping" experiment in the glasshouse is used as a model to check for rhizosphere effects on plant growth and mineral nutrition.
ObjectiveTo gain a holistic understanding of resource-driven and regulatory processes in agricultural and natural ecosystems.
Develop skills on the critical analysis of scientific papers.
Define explanatory hypotheses, identify knowledge gaps for further investigations.
Carry out a multi-disciplinary experiment that involves aspects of soil, (micro-)biology, plant physiology, pathology, and ecology.
Develop manual skills in the set up of a glasshouse experiment, in soil and plant analyses, and in isolation and DNA-based characterisation of rhizobia.
Gain insights on basic methods to analyse (bio-)chemical, molecular genetic, and graphical data.
Discuss and interpret data in the context of the literature.
Prepare a research report in the format of a scientific paper and a poster in the format of a conference paper, partially alone and partially in small groups, using data obtained from the glasshouse experiment.
ContentThis course is designed to stimulate thinking and promote critical analysis of important processes that occur in the rhizosphere. As part of this course, the knowledge acquired will be used for analysing and interpreting experimental data, as well as, preparing a scientific report and conference-type poster.

The course will cover the relative importance of spatial scales and various physicochemical and microbiological dynamics as influenced by roots. We will discuss root traits and activities that influence the immediately root-surrounding soil and thereby contribute to mineral nutrient mobilization and immobilization. An overview of the most relevant root-microbe symbioses for agroecosystems will be provided and root and microbial traits discussed, which could be of use in efforts towards utilization of intercropping and bioinoculants as a possible means of reducing energetically expensive inputs to farming systems. A special emphasis will be given to the importance of physicochemical features of soils and the chemical forms (= species) of elements important for plant uptake.

Practical experience will be gained with setting up a glasshouse experiment, soil and root sampling, basic soil and plant analyses, isolation of rhizobia, determination of the number of colony forming units (CFU), assays to screen for phosphorus and zinc solubilizing bacteria, DNA extraction, PCR amplification, and restriction fragment length polymorphism analysis (RFLP) of host range determining symbiosis-specific genes.

In short, the processes dealt with in this course occur on a small-scale and are generally (bio)chemical and microbiological in nature. Furthermore, they are generally not taken into account using current methods of agronomic management for plant production. However, they are increasingly being recognized as a potentially useful means of obtaining a resource-efficient and hence, economically and environmentally sustainable agricultural system, including for ecosystem restoration. Therefore, the course will invite for critical reflections and exemplify challenges in translating knowledge from scientific studies and ecology into application for plant production.

Prerequisites / NoticeWe ask all course attendees of the agricultural sciences to have passed the exams at the end of the lectures Plant Nutrition I and II (Nutrient cycling in agroecosystems) by Prof. E. Frossard. All others, have to have successfully worked through the e-learning module Plant Nutrition I by Prof. E. Frossard:

Remark: The course is designed to be complementary to those on Radioisotopes in Plant Nutrition (751-3405-00L), and Nutrient Fluxes in Soil-Plant Systems (751-3404-00L), although some thematic overlaps cannot be avoided. Special emphasis is given to plant-microbe-soil interactions and an appreciation of whole plant functioning in the ecological context. You will familiarize yourself with bacterial isolation, cultivation, enumeration, as well as, molecular detection, discrimination and identification techniques for rhizosphere and root-associated microbes.
Marking will consider the efforts and outcome of work by the individual participant as well as results of work in small groups. Activities for the course will result in posters and reports in the format of a conference and scientific paper. Reports will be due on Friday January 6, 2017.
Maximum number of participants: 18 (Attention: Admission will be on a first come first served basis - inscribe early!).
Students of D-USYS will be reimbursed via bank transfer for train and bus tickets of the zones 121 and 122 (Please send all tickets with the bank details to Christiane Gujan (Link).
