“…An altered nutrient status, e.g. enhanced release of Ca, Mg, K and Mn from decomposing litter, as proposed by Berg (1986), Fritze (1988) and Ohtonen et al, (1990) is another future question for the Oulu area.…”

Abstract. The biological activity and the amount of living fungal mycelium in the mor humus of pine forests around an industrialized city were studied. The activities were lower in the more polluted zone than in a cleaner one but varied between sites within the zones. The relationship of these activities to the microbial environment was determined in both the total data and in the various zones separately. Soil respiration rate was positively related to ammonium nitrogen concentration of the humus in the less polluted zone but negatively in the more polluted zone, while it related negatively to total nitrogen concentration of the humus in the entire data set. DHA was partly accounted for by the variation in acidity parameters, and best by pH(CaCl,), with a positive relation. The length of FDA active fungal mycelium showed no significant variation between the zones or sites, and was thus poorly explained by the environmental variables. The weather conditions prevailing at two seasons did not explain any variation of the activities or the length of FDA mycelium, though the biological variables were in general positively related to the moisture of the humus.

“…In recent years the issue has gained a larger importance as several authors have connected the reduced rate of organic matter decomposition with the anthropogenous pollution of the soil environment by heavy metals and acid rain (Berg, 1986a;Bieńkowski, 1990;Fritze, 1991;Laskowski and Berg, 1993;Ohtonen et al, 1994). Also, particular investigations show a remarkable increase in heavy metal concentrations as altitudes rise (Pb, Cd, Zn, and S in the northern and eastern Alps- Zechmaister, 1995, Pb in the Tatra Mts.…”

“…Decomposition has been less studied in urban environments, and past terrestrial urban decomposition studies mostly focused on comparisons along urban to rural gradients (e.g. McDonnell et al 1997) and on the effects of urban pollution on litter chemistry and decomposability (Fritze 1988;Cotrufo et al 1995;Carreiro et al 1999). When comparing decomposition rates among forest stands of similar age and composition across urban to rural gradients, these studies found that decomposition rates were sometimes more rapid in the urban environment, likely because of warmer temperatures and more earthworms in urban stands Pouyat and Carreiro 2003).…”

Decomposition of tree leaf litter on pavement: implications for urban water quality

et al. 2013

Leaf litter may be an important source of nutrients to stormwater and ultimately contribute to eutrophication of surface waters associated with urbanization. Thus, understanding decomposition and nutrient release from leaf litter that falls on impervious surfaces is important for stormwater management. However, few studies have examined leaf litter decomposition in the unique urban environment of the street gutter. We compared decomposition of leaf litter of five street tree species in a parking lot gutter in St. Paul, Minnesota, USA. In contrast to our expectations, comparisons with past studies revealed that litter decomposed more rapidly in the gutter than in nearby natural areas. And decomposition rates were as rapid as those measured in other urban settings (forests and streams), with most species losing 80 % of their initial mass after 1 year. Litter of most species had retained more than half of its initial N and P after 1 year. However, in contrast to N, litter P dynamics largely were uncoupled from litter mass dynamics, with litter P increasing and decreasing unpredictably over the year. Shortterm (24 h) laboratory studies revealed that litter had the potential to lose a high fraction of its initial P, with high variation among species (from 27 to 88 %), and a smaller fraction of its initial N (<10 %) via leaching. Thus, street tree species may differ in their potential contributions to nutrients that are released during decomposition. Our results suggest that careful selection of street tree species and timely removal of litterfall have significant potential to reduce nutrient fluxes from streets to storm drains, particularly for P.
