Contrasting

Order By: Relevance

“…Contrasting results have also been reported; decomposition (respiration activity) of the surface organic layers of a podzol horizon was stimulated when these layers were mixed with mineral soil from the B horizon (Salonius 1983). The respiration observed in clear-cut areas followed by mixing of organic matter with mineral soil horizons was higher than that in clear-cut areas without site preparation (Mallik and Hu 1997).…”

Smolander, A. and Heiskanen, J. 2007. Soil N and C transformations in two forest clear-cuts during three years after mounding and inverting. Can. J. Soil Sci. 87: 251-258. Transformations of nitrogen and carbon in the humus layer were studied in central Finland on two clear-cut forest sites for 3 yr after spot mounding and inverting together with an untreated control. In laboratory-incubation experiments, samples from the humus layer were measured for rates of C mineralization, net N mineralization and net nitrification, and the amounts of C and N in the microbial biomass were determined. Soil solutions were collected for 4 yr with suction lysimeters. Overall, site preparation did not affect the rate of net N mineralization significantly (per kg organic matter). In the first growing season, however, the mean rate of net N mineralization was higher in both site preparation treatments than in the untreated control. At first, net nitrification was negligible in all treatments, but in the second year it increased in both site preparation treatments. On the other site, C mineralization was lowest with inverting, but the amounts of microbial C and N were highest. This indicates a shortage of easily mineralizable C sources in inverted spots. In the soil solution collected below the humus layer, increased concentrations of NO 3 -N and total N were found in both site-preparation treatments but, during the fourth year, overall concentrations of N had declined. Pendant trois ans, les auteurs ont étudié la conversion de l'azote et du carbone dans l'humus de deux sites forestiers du centre de la Finlande coupés à blanc après bombement et inversion du sol à certains endroits. L'expérience portait aussi sur un site témoin non aménagé. Des échantillons de la couche d'humus ont été incubés en laboratoire ce qui a permis de déterminer le taux de minéralisation du C, la minéralisation nette du N, la nitrification du N ainsi que la quantité de C et de N dans la biomasse unicellulaire. Les auteurs ont prélevé des solutions de sol avec un lysimètre à succion quatre années durant. Dans l'ensemble, l'aménagement du site n'affecte pas le taux de minéralisation nette du N de manière significative (par kg de matière organique). Lors de la première saison végétative cependant, le taux de minéralisation nette du N était plus élevé aux endroits aménagés qu'au site laissé en l'état. La nitrification nette aux deux sites aménagés était négligeable au départ mais elle s'est accrue la deuxième année. Parallèlement, si la minéralisation du C était plus faible là où le sol avait été retourné, la quantité de C et de N dans la biomasse unicellulaire y était plus élevée. On en déduit que l'inversion du sol entraîne une pénurie de C facilement minéralisable. Dans la solution du sol recueilli sous la couche d'humus, les auteurs ont relevé une hausse de la concentration de N-NO 3 et de N total pour les deux sites aménagés suivie par une baisse de la concentration globale de N la quatrième année.

“…These results support our second hypothesis. Both Mallik and Hu (1997) and Pumpanen (2003) reported that mixing organic matter with mineral soil significantly increased R S rate. In detail, the organic matter decomposition rate was faster in buried sites than left on soil surface (Johansson, 1994;Lundmark-Thelin and Johansson, 1997).…”

“…) input may accelerate soil organic matter (SOM) decomposition due to the rhizosphere priming effects (Dijkstra et al, 2006). Another possible reason was the increase of soil C release caused by site preparation, because it can disturb soil structure, modify microclimate and enhance aeration (La Scala et al, 2005;Mallik and Hu, 1997). However, most researches did not investigate the effects of site preparation without plants on soil C release.…”

“…In addition, soil preparation could disrupt soil aggregates and transfer labile organic matter to soil microorganisms (La Scala et al, 2008), resulting in a reduction in the amounts of intra-aggregate soil organic C. Soil preparation also affects soil C release by modifying the soil surface microclimate, e.g., the soil water content and temperature (Mallik and Hu, 1997). Enhanced R S after soil preparation has been demonstrated (La Scala et al, 2005;Mallik and Hu, 1997), but the effects varied with on soil texture, initial soil C stocks and climate (Post and Kwon, 2000;Six et al, 2002). However, few studies have assessed the soil preparation effects on R S in subtropical soils (Feller and Beare, 1997).…”

“…Based on previously documented R S after similar site preparation (Guo et al, 2010;Mallik and Hu, 1997) and soil C stock change after afforestation in the same area (Huang et al, 2007), we hypothesize that (1) compared with brush clearing, controlled burning would decrease the annual cumulative R S because litter and organic carbon are consumed in burning; (2) overall soil preparation increases the annual cumulative R S , but spot soil preparation has less effects on the annual cumulative R S due to the small disturbance area; and (3) site preparation effects on R S may decline gradually over time, because of its direct effect on soil physical property might be weakened and lack of fresh organic matter input.…”

a b s t r a c tSite preparation, as an important procedure before afforestation, can affect soil C release. However, the effect of site preparation on soil C release has not been sufficiently investigated. Two site clearing treatments (brush clearing and controlled burning) followed by three soil preparation treatments (overall soil preparation, spot soil preparation, and no soil preparation (control)) were carried out in subtropical China. Soil basal respiration (R S ) and C release of biomass burning were measured as soil C release on an area basis from March 2011 to March 2013. The site preparations changed the soil C release in the first year but had no effects in the second year. Compared with brush clearing (control), controlled burning (control) significantly increased the annual soil C release (decreased R S but increased C release of biomass burning) during the first year. Within the brush clearing plots, overall soil preparation significantly increased the R S rate over eight months and resulted in an increase in annual soil C release during the first year compared to the no soil preparation. In contrast, spot soil preparation increased the R S rate only for three months and did not affect the annual soil C release during the first year relative to the no soil preparation. In the controlled burning plots, both overall and spot soil preparation increased the R S rate across six months, but only overall soil preparation caused a significant increase in the annual soil C release. Our study suggests that minimizing the disturbance of the site preparation would decrease soil C release. Concluding, the spot soil preparation followed brush clearing is a good choice for site preparation in term of soil C storage.

The short-term impact of coppice-with-standards management on soil in a Mediterranean holm oak forest was assessed to contribute to address appropriate recommendations to minimize possible negative effects of the silvicultural practices. For this purpose, soil surface features and topsoil properties were investigated in two representative areas located in a public forest in southwest Sardinia (Italy) and coppiced in the periods November 2012-March 2013 and November 2011-March 2012, respectively. Regardless of differences in soils and slope gradient, the same management, in terms of final density of trees standing after the clear-cut and accumulation of brushwood in strips along the maximum slope gradient, was applied in both areas. Field observations and laboratory data highlighted the disturbances caused to the soil by the silvicultural practices in the stands when compared with the undisturbed stands. These disturbances involved the almost complete removal of organic horizons, with consequent negative impact on organic carbon content, and the activation of erosion processes, mostly related to rainsplash erosion. Although soil mobilization locally largely exceeded the tolerable erosion rates, no extreme rainfall events occurred after the coppicing to produce critical situations at the catchment level. The adjustment of the final density of trees standing after the clear-cut in relation to soil properties, slope gradient and the possibility of extreme rainfall events, a different brushwood management and the restriction to the passage of wild animals would have strongly reduced the negative impacts on soils.
