The big picture: using wildflower strips for pest control
Sustainable Soils and Crops
Stephan conducted most of his research in rice-based systems in Africa and Asia, with a focus on soil science and agronomy. The most important topics he worked on were nutrient management, crop establishment, weed management, participatory variety selection, and biochar/bioenergy in rice-based systems. Most of his work was conducted in collaboration with colleagues from national research institutions in 7+ countries of south and south east Asia. In 2013, he took up a new position at the Australian Centre for Plant Functional Genomics (ACPFG) at the University of Adelaide. There, he was leading the phenomics group and supported colleagues with growth facilities and screening options for abiotic stresses. He developed a drone-based platform for field-based phenotyping, and he conducted a number of experiments on stress tolerance of GM wheat in South Australia and Western Australia. In 2017, he joined Rothamsted Research, where he is working on the agronomic application of the data produced by the African Soil Information Service (AfSIS), on new applications of infrared spectroscopy for soil and plant analysis, on new long-term trials on a large-scale rotation experiment, and on precision nutrient management and NUE for selected cropping systems.
