A seemingly mundane soil sample taken on the 4th December 1931.
There are a few anomalies here. In an average soil sample you would expect to find the following nutrients or elements:
- Major nutrients: nitrogen (N), phosphorus (P), and potassium (K)
- Secondary nutrients: sulphur, calcium, magnesium
- Minor nutrients: iron, manganese, copper, zinc, boron, molybdenum, chlorine
But in the sample we find the presence of Cobalt and a large amount of Sulphur which would be sure to raise eyebrows. There is also a tiny but still substantial amount of Palladium.
The key here is the 16% “Unknown” – including some magnetic properties.
This sheet explores soil sample 174. We at the archive have only discovered this and three others (12, 67 and 122). It is unclear how many were taken nor why so many are missing.
