This study was designed to examine the long-term effects of lime application and canopy removal on soil nutrient budgets in a mature European beech (Fagus sylvatica L.) forest. In 1989, trees were felled to create four 30-m wide circular gaps in this beech forest, and two of these gaps and the surrounding area were limed with 3 t ha(-1) of fine dolomite, whereas the remaining two gaps and most parts of the stand were not limed. Main nutrient concentrations in the forest floor and in the mineral soil were determined in 1989, 1997, and 2011. In addition, we examined the influence of liming and gaps on the forest floor organic matter. The significant effects of liming and gap creation on the forest floor dry mass in 1997 were no longer obvious in 2011, unlike their influence on the C and N pools, which was still significant in 2011. In the long-term, the forest floor C and N pools increased less in the limed and opened plots compared with the untreated stand, and the N pool only decreased in the mineral soil of the limed gaps. Soil acidity was reduced significantly 8 years after liming at any depth in the limed plots (limed stand, limed gaps) and in the deeper layers (5-40 cm) of the unlimed plots, indicating a general soil recovery from acid depositions in earlier decades. After 22 years, the pH values were still higher at 5 to 10 cm mineral soil depth in the limed plots, which partly reflected the higher base saturation in the mineral soil of the limed gaps. However, the pH values were surprisingly dropping from 1997 to 2011 in the upper soil layers of all plots. Overall, some effects of canopy opening and liming on soil nutrients lasted for more than two decades in this European beech forest."],["dc.description.sponsorship","China Scholarship Council; German BMBF"],["dc.identifier.doi","10.1097/SS.0000000000000085"],["dc.identifier.isi","000351670600001"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/32394"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1538-9243"],["dc.relation.issn","0038-075X"],["dc.title","Long-term Effects of Canopy Opening and Liming on Soil Nutrient Dynamics in a European Beech (Fagus sylvatica L.)

In two of the gaps and their surrounding areas, dolomite lime (3t ha(-1)) was applied. The study was designed to examine the long-term effects of lime application and canopy removal on element input via throughfall and output in seepage water at 80cm depth in this European beech forest. Throughfall and seepage water were collected in the unlimed gap center, the limed gap center and the undisturbed beech stand in 1991, 1992, 1993, 1996 and 2012. The canopy opening increased the seepage water acidity from 1991 to 1996. The pH values of the seepage water were higher in the limed gaps than in the unlimed gaps during the five study periods. The amount of annual throughfall and of seepage water were higher in the gaps during the study period; in 2012, the annual amounts of seepage water were significantly higher in the gaps than in the closed stand, whereas the input of most elements decreased from 1991 to 2012. The seepage water in the unlimed gaps had higher nitrate nitrogen (NO3-N) concentrations, but lower sulfate sulfur (SO4-S) concentrations than in the limed gaps in 1991, 1992, 1993 and 1996. The amount of leaching NO3-N and SO4-S in 2012 was, however, significantly higher in the limed gaps than in the unlimed gaps, while the input of nitrogen (N) and SO4-S was significantly lower in the limed gaps than in the closed stand. In general, the annual amounts of element input via throughfall were higher in the closed stand than in the gaps. However, the element output through leaching was much higher in the gap centers than in the closed stand. The net losses of aluminum (Al), calcium (Ca), magnesium (Mg) and manganese (Mn) were higher in the unlimed gaps than in the limed gaps and the closed stand in 1991. In 2012, 23years after liming and canopy opening, the effects of gaps and liming, and the interaction of gap and liming on element leaching, were still significant compared to the untreated stand. Overall, canopy opening reduced N, sulfate, Al, and base cation deposition in the long run. Canopy opening in combination with liming affected the seepage water acidity and the leaching losses of base cations up to 23years after canopy removal and liming in this European beech forest."],["dc.identifier.doi","10.1080/00380768.2014.990865"],["dc.identifier.isi","000353474500010"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37667"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Taylor & Francis Ltd"],["dc.relation.issn","1747-0765"],["dc.relation.issn","0038-0768"],["dc.title","Long-term effects of gap creation and lime application on element input and output in a European beech (Fagus sylvatica L.) forest"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The results did partially support the hypothesis that the combined or single effects of liming and/or canopy removal on the litter production and decomposition lasted for more than 20 years. The main results were: (1) Along with beech regeneration, the annual leaf litter input in all study plots was higher for the period 2000-2010 (2.9 Mg ha(-1) yr(-1)) than for 1990-1997 (2.5 Mg ha(-1) yr(-1)), and the differences among the treatments were getting smaller; (2) The mass of beech leaf litter fall was higher in the stands than in the gaps; (3) Liming accelerated the fine root and OF layer litter decomposition in the period April 1992 to July 1993, and fine root and leaf litter from June 1996 to September 1997, but this effect was not observed in the period March 2012 to July 2013; (4) The gap effect alone did not accelerate the litter decomposition rate in the first period, but in the second and third periods; (5) 23 years after liming and canopy opening, the quality of the leaf litter was different, and the canopy opening continued to accelerate both leaf litter and fine-root decomposition.
