成果の概要

Under the Africa upland farming system project, we extracted the DNA of soil samples collected from the 2023 green manure and maize trials at Savanna Agricultural Research Institute (SARI) on-station and farmer’s fields. We re-analyzed the amino nitrogen of xylem saps from the 2023 soybean field experiment to assess the nitrogen fixation of the plant in field conditions. Under the TERRA Africa project, we set up a phosphate-rock-rhizosphere soil composting at the University for Development Studies (UDS).
