December 5th is World Soil Day. Only healthy soils guarantee high yields over the long term, which is why Agroscope researchers are focusing on this ecosystem.
The aim of the ‘Proof by Underpants’ project was to obtain exten-sive information on the soil quality of gardens and farms, for the first time with the help of the general population. Initial results show that humus plays a key role in the soil, helping it cope better with climate-induced drought.
