“…This in turn highlights the role of surface runoff in the elution and transport of chemicals. Our finding is contradictory to some other studies in which a relatively slow release of nutrients from plant detritus has been observed (Hongve, 1999;Hirobe et al, 2004). However, the cited studies involved only fresh plant detritus which releases N, P and other elements slowly during its gradual decomposition.…”

“…The chemical properties of runoff may vary significantly and depend, inter alia, on catchment area properties such as geomorphology, vegetation and the degree of human impact. In forest ecosystems, the input and output of essential nutrients is relatively small when compared to their total amount of cycling within the system (Hirobe et al, 2004). However, the elements exported from wooded catchments may have a considerable impact on the quality of surface waters (Irfanullah, 2009;Park et al, 2011).…”

-Surface runoff can supply lakes with a variety of chemical substances -their type and quantity may significantly vary and depend on the characteristics of the catchment area: geomorphology, phytocoenosis type and degree of human impact. In this study we investigated the physicochemical properties of the surface runoff water collected from the wooded catchment of Lake Piaseczno Duze (LPD, Drawa National Park, Poland) covered by a monoculture of Scots pine (Pinus sylvestris) and mixed forest with white birch (Betula pubescens) as the dominant tree. Experimentally, we also aimed to study the leaching of nutrients from pine and birch litter. Throughout the investigated period runoff waters had low pH, brown colour and high levels of dissolved organic carbon (DOC) -most likely induced by humic acids. Furthermore, considerable levels of nitrogen (N) and phosphorus (P) were found. The highest concentrations of nutrients were observed in runoff collected after heavy rainfall and snow melting. Runoff from the coniferous area contained significantly higher levels of DOC but lower concentrations of N and P compared to runoff collected from the birch-dominated forest. Similar physicochemical conditions were observed in the leaching experiment. Moreover, it was found that the release of chemical substances from both coniferous and deciduous litter was rapid. Our study indicates that surface runoff from forest areas can significantly affect lake chemistry. Based on the simultaneous analyses of littoral water chemistry we suggest that it may contribute to LPD dystrophication through the transportation of high levels of acidic compounds.

“…Ca from litterfall is likely to stay longer on the forest floor than other elements. During litter decomposition in a primary forest in Borneo, Ca remained at almost 100% on a mass basis over a period of a few months in some species, but the process differed by species and litter characteristics (Hirobe et al 2004).…”

To investigate soil amelioration effects by older tropical fast-wood plantations, we examined the fine litterfall and accompanying nutrient flux of a 20-year-old Acacia mangium site over 3 years under a wet tropical climate in Sabah, Malaysia. The litterfall of a Swietenia macrophylla site and an Araucaria cunninghamii site was also examined for comparison. Annual nitrogen (N) flux through litterfall (kg N ha -1 ) was larger in A. mangium (207-223) than in S. macrophylla (126-153) or A. cunninghamii (72-94), whereas annual phosphorus (P) flux through litterfall (kg P ha -1 ) was considerably smaller in A. mangium (2.7-3.4) than in S. macrophylla (7.5-15.6) or A. cunninghamii (7.8-9.2). N flux through litterfall, forest floor N, and N concentration in topsoil (0-5 cm) were in the order of A. mangium [ S. macrophylla [ A. cunninghamii, but other element fluxes were not related to concentrations in soils. Our findings suggest that topsoil N increased because of a large N flux from litterfall. We conclude that these plantation trees, including A. mangium have the potential to produce a N flux in litterfall for the rapid return of organic N to soils larger than or equivalent to that in adjacent primary forests. However, the litterfall of a single species may lead to deficits of a particular element and cause nutrient imbalances. Using a mixture of fertilizer tree species or applying mixed litter might be a better solution.

“…Urban runoff, in turn, can contain significant concentrations of persistent contaminants such as oil derivates, heavy metals and polycyclic aromatic hydrocarbons, leading to contamination of municipal surface waters (Choe et al 2002;Azizuddin et al 2014;Rzymski et al 2014). In forest ecosystems, it is claimed that the output of nutrients is relatively small when compared to their total amount cycling within the system (Hirobe et al 2004). However, the elements exported from the wooded catchments may still have considerable impact on the quality of receiving waters (Strobel et al 2001;Vuornenmaa et al 2002;Astrom et al 2004;Park et al 2011).…”

“…The potential role of surface runoff in increasing the trophy of water bodies was also indicated (Klimaszyk and Rzymski 2011). It is likely that different types of forest litter, coniferous, mixed and deciduous, may have a different impact on the chemistry of runoff due to varying quantities of chemical compounds in litter produced by different tree species (Klimaszyk and Rzymski 2011;Hirobe et al 2004). For example, higher levels of phosphorus and nitrogen are leached from deciduous litter, while coniferous litter is usually richer in organic matter and humic acids (Klimaszyk andRzymski 2011, 2013).…”

Contribution of surface runoff from forested areas to the chemistry of a through-flow lake

The role of surface runoff from forested areas in chemical cycling and freshwater ecology is still not completely understood. Changes in total precipitation and increase in heavy rainfalls may, however, in some regions promote the effect of runoff in aquatic environments. In this study, we aimed to investigate the physicochemical properties of the surface runoff occurring within the wooded catchment area of a through-flow lake (Poland, Europe). Samples were collected over a 2-year period from slopes overgrown by the monoculture of Scots pine (Pinus sylvestris) or mixed forest dominated by European beech (Fagus sylvatica) and Scots pine. At the same time, the chemical properties of littoral and pelagic zones were analysed. Waters overflowing both slopes were found to have low pH, high colour and relatively high content of dissolved organic carbon and nutrients. Compared to coniferous site, the runoff from mixed forest was represented by significantly higher concentrations of organic matter, nitrogen, phosphorus and calcium ions. The greatest changes of the studied chemical parameters were noted in runoff occurring during heavy rainfall and snow melting (coniferous slope) or after shedding of leaves (the mixed forest slope). Surface runoff was revealed to be less important source of chemical loads in basins with direct river inflow but for more isolated basins it may be a significant factor affecting water quality.
