Substrate and Topsoil Impact on Soil Water and Soil Temperature in Arctic Diamond Mine Reclamation

Soil properties in the Arctic are insufficiently explored and documented, particularly extensive monitoring of soil water temperature over a period time. critical for understanding land surface atmosphere interactions considered key factors revegetation during mine reclamation. This study assessed how substrate topsoil influenced content at reclaimed diamond Northwest Territories Canada. Three substrates (crushed rock, processed kimberlite, lake sediment) with without were used. Mean air changed little from year to year, although summer showed slightly increasing trend. Both annual precipitation sharply declined was more by than placing 10 cm on it. Processed kimberlite had greater retention characteristics sediment crushed rock (significantly). Surface lower topsoil, suggesting that not enough influence temperatures either or topsoil. suggests could be used as component management reclamation this extreme environment.
