An increasing number of studies are now reporting the effects of ocean acidification on a broad range of marine species, processes and systems. Many of these are investigating the sensitive early life...
Effects of N and P fertilization on the greenhouse gas exchange in two northern peatlands with contrasting N deposition rates

The sensitivity of oceanic CO2 uptake to alterations in the marine biological carbon pump, such as brought about by natural or purposeful ocean fertilization, has repeatedly been investigated by studi...
Mineral fertilization did not affect decay of old lignin and SOC in a 13C-labeled arable soil over 36 years
