Influence of pH and temperature on microbial activity, substrate availability of soil-solution bacteria and leaching of dissolved organic carbon in a mor humus
TL;DR: In this article, the authors investigated how pH and temperature influenced fluxes of dissolved organic carbon (DOC), CO2 and bacterial activity in a laboratory experiment with upper (F) and lower (H) mor humus layers from a limed and an unlimed plot of Norway spruce (Picea abies (L.) Karst).

TL;DR: In this paper, the authors identify, address and rank knowledge gaps in our understanding of five major soil C and N interactions across a range of scales -from molecular to global -and ranked the identified knowledge gaps according to the importance they attached to them for functional descriptions of soil-climate interactions at the global scale, for instance in general circulation models.

TL;DR: In this article, the concentration of organic A1 species was linearly correlated with the concentrations of dissolved organic C (r,2, varied from 0.38 to 0.69 with p, < 0.001).

Soil changes in forest ecosystems: evidence for and probable causes
Dale W. Johnson,Malcolm S. Cresser,S. Ingvar Nilsson,John Turner,Bernhard Ulrich,Dan Binkley,Dale W. Cole +6 more
TL;DR: A review of the literature on forest soil change in North America, Central Europe, and Australia reveals that changes are occurring in both polluted and unpolluted sites at a greater rate than previously suspected as discussed by the authors.

Experimental work related to nitrogen deposition, nitrification and soil acidification--a case study.
TL;DR: Fertilization has increased the ionic strength of the soil solution due mainly to sulphate in the phosphate fertilizer, but also nitrate at the highest fertilization level, which has caused an increase in total aluminium and a decline in pH.
