Would it be suitable for soil reclamation in general?
Yes
Justification, references

Magas ásványi anyag tartalmának köszönhetően alkalmas lehet. Nagy karbonáttartalmának köszönhetően savanyú talajok javítására hasznosítható. Jó kiegészítő komposzthoz, növeli annak nitrogén, foszfor és kálcium tartalmát.
