Short summary
Coastal wetland restoration often removes invasive plants, but its effects on deep soil carbon are uncertain. We compared plastic mulching and deep tillage for eighteen months in an invaded wetland. Mulching reduced soil salt, increased microbial biomass in deep soil, and coincided with lower carbon and iron-bound carbon through one metre of soil. These results show that restoration methods can affect hidden deep soil carbon, so monitoring should include the whole soil profile.
