Really enjoying my time in πŸ‡ͺπŸ‡Ή as part of the CROSSROADS -SSA project. Looking at #underutilsed #plants and investigating their potential for improving #soilhealth.

Great day in the field yesterday at some agropastoral plots south of Hawassa.

Day 2 of meetings in Hawassa, Ethiopia is planning for CROSSROADS-SSA led by Jo Smith This project explores under-utilised plants to restore soils through biodiversity. An add-on is a rainfall siimulator we built last week to explore soil erosion mitigation. @uniofaberdeen.bsky.social

Happy world soil day! Just about… 🌱 This year’s theme is β€œCaring for Soils: Measure, Monitor, Manage” which is about using soil data to make the right decisions.

As someone who loves photography, I wanted to share a barley root system forming its own unique soil. Enjoy!
