Most of what gardeners are told about soil is repeated, not tested. In Search of Soil takes one claim at a time and checks it. Sand fixes clay soil. Loam is the ideal soil. Heavy clay is heavy. Each episode puts a single claim on trial against peer-reviewed research and university extension work, then reaches a verdict — busted, half true, confirmed, or occasionally the wrong question entirely. Between episodes, Diego sits down with the soil scientists, agronomists and researchers whose work those episodes are built on. The people who ran the studies, drew the charts, and know better than anyone where the evidence actually stops. No product pitches. No hacks. Every number on the show comes with a source, and the ones Diego worked out himself are labelled as his own arithmetic. Hosted by Diego Footer.
