“…Results also suggested soil NH 4 -N and total P content strongly associated with soil fungal and bacterial communities in broadleaf forests, but not in coniferous forests. This suggested that the relationship between soil microbial communities and soil properties can be different between boreal broadleaf and coniferous forests, which is consist with previous observations in temperate 45 and subtropical forests 46 . Another interesting result is that, soil fungal and bacterial communities in these southern boreal broadleaf and coniferous forests are significantly associated with soil total or available K content.…”

Little is known about the relationship between soil microbial communities and soil properties in southern boreal forests. To further our knowledge about that relationship, we compared the soil samples in southern boreal forests of the Greater Khingan Mountains—the southernmost boreal forest biome in the world. The forests can be divided into boardleaf forests dominated by birch (Betula platyphylla) or aspen (Populus davidiana) and coniferous forests dominated by larch (Larix gmelinii) or pine (Pinus sylvestris var. mongolica). Results suggested different soil microbial communities and soil properties between these southern boreal forests. Soil protease activity strongly associated with soil fungal communities in broadleaf and coniferous forests (p < 0.05), but not with soil bacterial communities (p > 0.05). Soil ammonium nitrogen and total phosphorus contents strongly associated with soil fungal and bacterial communities in broadleaf forests (p < 0.05), but not in coniferous forests (p > 0.05). Soil potassium content demonstrated strong correlations with both soil fungal and bacterial communities in broadleaf and coniferous forests (p < 0.05). These results provide evidence for different soil communities and soil properties in southern boreal forest, and further elucidate the explicit correlation between soil microbial communities and soil properties in southern boreal forests.

“…In addition to litter manipulation experiments (litter removal and litter addition treatments), we further classified straw harvesting and residue removal in cropland as "litter removal", straw mulching with the equivalent of annual aboveground litter production as controls (e.g. Akhtar et al 2018b;Wang et al 2019), but straw mulching in excess of the annual aboveground litter production as "litter addition" (e.g. de Abreu Sousa Junior et al 2018;Zhang et al 2015a).…”

“…The response of soil C to altered litter inputs is probably largely determined by the tree species grown in each plantation. For example, Wang et al (2019) found that doubling aboveground litter inputs significantly increased soil C content and metabolism of labile C in oak plantations but not in pine plantations. In addition, plantation management practices will strongly influence the response of soil C to changes in litter inputs, for example, by altering soil nutrient availability (Zhao et al 2017), via straw harvesting (Blazier et al 2008) or thinning (Jandl et al 2007).…”

“…Forest thinning did not have consistent effects on soil C content across the soil profile, which can be attributed to changes in other ecosystem and soil properties as a result of management practices. For example, forest thinning can reduce aboveground litterfall for several years, but thinning also results in large inputs of residues (Jandl et al 2007) and increases fine root biomass (Asaye and Zewdie 2013;Wang et al 2019), which may compensate for the loss of litter inputs. The impact of thinning on soil C storage also varies strongly depending on the intensity and the length of thinning intervals (Jandl et al 2007), which may explain why we found no relationship between treatment duration and the magnitude of thinning effects on topsoil C content (Fig.…”

Aims Aboveground plant litter inputs are important sources of soil carbon (C). We aimed to establish how experimentally altered litter inputs affect soil C to 1-m depth across different ecosystems, and over different timeframes. MethodsWe performed a meta-analysis of 237 studies across 248 sites worldwide to assess the influence of treatment magnitude, treatment duration, initial soil C content, and climate on the response of soil C to altered aboveground litter inputs. ResultsOverall, soil C content was lower under litter removal, but higher under litter addition compared to controls. The effects of litter manipulation were apparent throughout the soil profile and were related to treatment magnitude. Soil C content declined markedly with increasing duration of litter removal, whereas the positive effect of litter addition attenuated over time. Cropland management practices (bare fallow or additional straw incorporation) had similar effects on soil C to litter removal and addition treatments. ConclusionsOur study reveals rapid and consistent changes in soil C content with altered litter inputs and provides important insights into plant residue management to enhance soil C sequestration. We highlight the need for long-term experiments, with a greater focus on the processes underpinning soil C storage in different ecosystems.

“…The data derive from an investigation undertaken to see the influence of detritus input and removal treatments on carbon metabolism in broadleaf and coniferous plantations [1]. Soil microbial C metabolism was measured with Biolog EcoPlate™, which was incubated at 25 °C for 240 h. The absorbance was measured with a micro plate reader (Synergy H 1 , Biotek, Vermont, USA) at 590 nm every 12 h. The data included the average absorbance data of triplicates every 12 h for 240 h for 50 soil samples.…”

This article presents soil microbial carbon metabolism data under different detritus input and removal treatments (DIRT) in broadleaf and coniferous plantations in the Tashan Forests in Feixian County, Shandong Province, China (35°10′–36°00′N, 117°35′–118°20′E). The local annual air temperature is 13 °C, and the annual precipitation is 700 mm. The soil belongs to Phaeozems. The effects of DIRT on soil microbial carbon (C) metabolism in oak (Quercus variabilis Bl.) plantations and pine (Pinus thunbergii Parl.) plantations were assessed. There were five treatments for each plantation type, including: a control; doubling aboveground litter input; no aboveground litter input; no roots; and no detritus inputs. Soils were sampled after one year and nine months of DIRT. Soil microbial C metabolism was measured by EcoPlate™, which contained 31 different C substrates. The absorbance was measured with a micro-plate reader (Synergy H1, Biotek, Vermont, USA) at 590 nm every 12 h for 240 h. The data are based on 50 samples (two forest types × five C input treatments × five replicates); three replicates of the samples were taken. Interpretation of the data can be found in “Carbon input manipulations affecting microbial carbon metabolism in temperate forest soils – a comparative study between broadleaf and coniferous plantations” (Wang et al., 2019). The data can be used for studying the roles of aboveground and belowground inputs to soil C stabilization.
