Research shows that invasive earthworms are damaging forest soils and are a menace to species diversity. The problem is most often associated with formerly glaciated regions, where native populations of earthworms are not present. Comparing soil in front of the invaders to post invasion conditions demonstrates that these worms cause soil compaction, reduced soil fertility, and increased erosion. It appears that these invaders are capable of alterations deep enough into the soil profile to result in a change in soil taxonomic classification at the order level. Other concerns are damage to rhizosphere functions, impairing soil carbon sequestration capacity.

Carbon sequestration in tallgrass prairie soil

paleorthid — Mon, 27 Feb 2006 01:11:00 -0500

Over the course of an eight-year open-top-chamber CO2-enrichment (to twice ambient concentrations) study of a pristine (annually burned) tallgrass prairie north of Manhattan, Kansas, USA, which was composed of a mixture of C3 and C4 species, Williams et al. measured changes in the active, slow and passive pools of carbon (C) and nitrogen (N), with the goal of determining how they were impacted by the doubled atmospheric CO2 concentration of their reasonably long-term experiment.

transect points: Toronto Star reports on terra preta and terra mulata

The article highlights some important nuances. Terra mulata, the lighter type of terra preta, covers much more area than the celebrated black type central to the concept of terra preta.

transect points: Carbon Coalition Against Global Warming

comment: heartburn over an expectation that the scientific community has promoted that leads us to believe that we can create a significant, persistent sink of carbon by using established farming and forestry approaches.
