AfSIS DB is a web-based data portal for uploading, searching, and downloading raw soil and plant chemistry analyses. It was created for the Africa Soil Information Service (AfSIS), which has been building workflows, protocols, and technologies for measuring and monitoring the soil and landscape resources of Africa. Through the collaboration of many partners, AfSIS has built the world’s largest repository of publicly available chemistry data about soils from the African continent.

AfSIS DB provides centralized storage, lookup, and distribution of raw, primary source data for soil and plant chemistry. This includes georeferences and raw measurements extracted directly from laboratory machinery, without any transformations applied. Scientists and outside institutions are welcome to remix this primary source data however they like.

Below are a few screenshots of the internal functionality. We also provide video tutorials (link 1, link 2) and computational notebooks demonstrating how to interact with AfSIS DB.

AfSIS has been an enormous undertaking made possible through the joint efforts of many organizations. The people involved with this project include not only analytical chemists and soil scientists in laboratories, but also intrepid field crews that have traversed deserts and scaled mountains under the hot sun to extract soils out of the ground, in pursuit of science. Below is an incomplete list of organizations that have contributed data to this archive. We thank all our partners for their tireless contributions to the AfSIS project.

  • Africa Soil Information Service (AfSIS)
  • Government of Tanzania
  • World Agroforestry Center (ICRAF)
  • The Center for International Earth Science Information Network (CIESIN)
  • Rothamsted Research
  • Quantitative Engineering Design (QED)
