Abstract:

This research was conducted to study the population and diversity of soil and leaf litter mesofauna in arable soils under different types of vegetation and slope at the Agriculture Experimental Field (AEF) of University of Lampung. This study was designed to use the survey method. The soil and leaf litter samples were taken from different vegetation and slope classes. Observational variables included population and diversity index of soil mesofauna (H’), soil temperature, soil moisture content, soil pH, soil organic-C, soil total-N, and soil C/N ratio. The data of population distribution were presented in a boxplot diagram and the correlation between soil properties and mesofauna population or mesofauna diversity index were presented. The results showed that the most abundant soil mesofauna was observed in the plots with sugarcane vegetation, either sampled at the end of dry season (November 2015) or at the beginning of rainy season (April 2016). However, the highest number of leaf litter mesofauna was found in the plot with cassava vegetation. This result suggests that the cassava leaf litter most likely became the preferred substrate for mesofauna. In all treatments, the value of mesofauna diversity index (H‘) was categorized as low according to the Shannon-Weaver index. Two dominant orders frequently found in almost all vegetation types were Acarina and Collembola. The results of correlation analysis indicated that only soil pH sampled on November 2015 was positively correlated with the mesofauna population (range of pH 5.0 to 6.6). Soil moisture content sampled on November 2015 and soil C/N ratio sampled on April 2016 were positively correlated with the diversity index of soil mesofauna, respectively. Soil total-N sampled on November 2015 was negatively correlated with the soil mesofauna diversity index. The increase of leaf litter biomass appeared to promote the increase of the leaf litter mesofauna population, but not the diversity index.Keywords: diversity index, leaf litter, soil mesofauna, vegetation

Abstract:

This research was conducted to study about abundance and diversity of soil and litter mesofauna to the effect of forest cover change that occurred in the Pemerihan Resort, Bukit Barisan Selatan National Park. This research was compiled in a completely randomized design (CRD) and there were four different lands, which were: (1) primary forest, (2) coffee plantation, (3) corn field, and (4) grassland. The observation of mesofauna was taken in soil and litter from four different lands cover. The variable of observation were mesofauna abundance and diversity index, soil chemical properties (pH, organic carbon, total nitrogen, P available, and exchanged potassium), and soil physics properties (bulk density, soil temperature, humidity, and porosity). Data were analyzed using F test and further test using least significant differences (LSD) at 5%. The results showed that the different of lands cover affect the diversity index of litter mesofauna, the abundance of litter and soil mesofauna, yet did not affect the diversity index of mesofauna underground. However, the abundance and diversity index of soil and litter mesofauna in the primary forest was higher than the other lands.

Abstract:

The effects of two herbicides (atrazine and alachlore) and two insecticides (fipronil and carbofuran) were evaluated on soil mesofauna and organic matter decomposition, in a maize field with normal culture conditions, using the litter-bag method. The litter-bag method was discussed and considered to be adapted for this type of in situ study, especially under normal culture conditions, where it is difficult to find real control plots. However its adaptability is conditioned by some utilisation factors. The litter-bag colonization and modifications of this colonization by phytopharmaceuticals were interpreted using functional groups classification. Except for alachlore, herbicides appeared to have no differentiated effect on mesofauna. Accordingly, fipronil significantly affects the dynamics of bag colonization by selected groups belonging to soil mesofauna.

Abstract:

<p>The edaphic mesofauna comprises litter-decomposing organisms deposited on the surface that directly participate in the process of nutrient cycling and the formation of organic matter, essential to maintain soil quality. The aim of this research was to quantify the abundance, richness and diversity of the edaphic mesofauna in caatinga environments in the semiarid region of Alagoas. For this research, two areas of native caatinga were selected, located in Olho D’Água do Casado (area I) and Delmiro Gouveia (area II), in the state of Alagoas, whose areas of vegetation are characterized as hypoxophilous caatinga. The collections were conducted bimonthly between February 2012 and October 2013. For the collection of mesofauna, twenty pre-selected points were used, from which samples of soil + litter were taken, with the aid of metal rings, 5 cm soil depth. The samples were taken to the battery of extractors Berlese-Tullgren, which was modified for the extraction of the organisms, and later the captured organisms were quantified and identified in the order of the large taxonomic groups. To measure the wealth of the groups, Shannon’s Diversity Index and Pielou’s Equability Index were used. The dominant groups of soil mesofauna in area I were Acarina, Collembola, Isoptera and Psocoptera, while in area II were Acarina, Collembola, Psocoptera and Hymenoptera.</p>

Abstract:

The use of inorganic fertilizers and pesticides can change the agroecosystem gradually. These changes may result in a decrease in the diversity of soil organisms. These organisms are very important in the decomposition process of reforming the organic matter into compounds that are readily absorbed by plants. Other changes include a change in the soil structure which will affect the soil chemical and physical characteristic and ultimately affect the soil productivity leading to a decreased agricultural product. The return of the remains from harvest, litter and crop residues from coffee and cocoa crops to the soil will provide energy for soil organisms and it will help maintain the soil environment that supports the life of other organisms. This research aimed at identifying the composition and diversity of mesofauna formed by the composted organic matter in cocoa and coffee plantations. Soil sampling was conducted on coffee and cocoa plantations in the Onelako village of Ndona District. Soil sampling was conducted in September 2010. Soil sampling used Neuman method of 0-15 cm and 16-30 cm depth. Each soil sample was taken to the laboratory. The separation of mesofauna from soil used Berlese-tullgran method that had been modified for 4 days. The separated Meso fauna was identified under the light microscope. The result of this research showed that the highest composition of mesofauna decomposer of organic matter in cocoa and coffee vegetation is Collembola. Collembola is very tolerant to acidic soil condition and they are dominant in the soil and surface habitats that contain lots of litter. Collembola is microarthropods that have large distribution both in quantity and diversity. The highest diversity of mesofauna on coffee vegetation is 1.525 and on cocoa, vegetation is 1.273. It was also noted that at a depth of 0-15 cm there was a higher concentration of mesofauna in the coffee vegetation area, which was about 7.3960, while in the cocoa vegetation there where 3.6376. The high level of the diversity index caused an increase in decomposition and therefore better soil fertility.

Abstract:

Abstract The dynamics and performance of soil biota during forest rotation were studied in monoculture beech stands forming a chronosequence of four different age-classes (30, 62, 111, 153 yr). Biomass was monitored in major groups of microflora, microfauna, mesofauna, and macrofauna. Resource availability (litter layer, soil organic mater), biomass of the two dominant decomposer groups (microflora, earthworms) as well as the biomass of mesofauna and microfauna were found to remain quite stable during forest succession. Nevertheless, the marked increase of the biomasses of primary decomposers (fungi, saprophagous macroinvertebrates) in the 62-year-old stand, followed by an increase of the biomasses of macropredators in the 111-year-old stand, indicate substantial changes of several components of edaphic communities during forest development. However, constant values of soil respiration suggest that the overall performance of the soil food web does not change during beech forest succession. Thus, the decomposer system of lowland managed beech forests on calcareous soils seems to be very stable over time. We suggest that earthworm activity might have masked impacts of forest development on other soil biota and led to an astounding stability of decomposer assemblages during beech forest rotation.

Abstract:

Important for soil quality, the edaphic fauna is indicative of an environment in equilibrium. The study aimed to identify the macrofauna and mesofauna organisms of the soil in a fragment of riparian forest. The work was carried out in a fragment of ciliary forest on the farm Tamanduá, municipality of Santa Terezinha, Paraíba. The macrofauna was quantified in soil samples collected at different depths (0-5 cm and 5-10 cm) using the TSBF method. For the mesofauna was collected randomly in the same area, samples of soil + litter in the depths 0-5 cm and 5-10 cm using metal rings. The design was completely randomized in a 4 × 2 factorial scheme (4 seasons, 2 depths), with 5 replicates, the means being compared by the Tukey test. The main orders of the macrofauna were: Hymenoptera, Coleoptera, Isoptera, and Enquitreídeos being the order of greater proportion in the two depths to Hymenoptera. There were a higher population and diversity of soil macrofauna in the superficial layer (0-5 cm). For the mesofauna were found in the samples organisms belonging to the groups Acarina and Collembola, being the order Acarina the most representative in the two depths evaluated. The environment of riparian forest presents greater diversity and density of macrofauna and mesofauna of the soil in the layer of 0.0-5.0 cm of depth, which presents greater food supply and conditions favorable to the survival of these organisms.

Abstract:

As part of the long-term soil productivity study in central British Columbia, we examined the effect of soil compaction and organic matter removal on trembling aspen (Populus tremuloides Michx.) litter decomposition. We compared three levels of organic matter removal (stem-only, whole-tree harvest, and scalped mineral soil) and two levels of compaction (no compaction and heavy compaction) in a factorial design replicated as blocks on three sites. Whole-tree harvesting significantly increased litter decomposition rates compared to stem-only (by 36%) and scalped (by 41%) treatments. Soil compaction had inconsistent effects on decomposition rates (k) for forest floor and scalped treatments and, overall, did not significantly affect litter decomposition rates. Litter on scalped plots had higher rates of nutrient translocation than litter on forest floors. We found the treatments altered soil heat sums, so changes in temperatures at the soil surface might be partly responsible for the changes in decomposition rates. We could not detect differences in soil mesofauna populations collected from the litter bags, so treatment effects on fauna probably had less influence than microclimate on decomposition rates. The effects of these early changes in litter decomposition on biological productivity will be part of the ongoing long-term soil productivity study. Key words: Litter decomposition, soil compaction, scalping, whole-tree harvest, nutrient translocation

Abstract:

Fertilization and/or the accumulation of organic matter from plant residues can influence the composition of soil and litter community. The goal of this study was to evaluate the effects of P and K fertilization on total faunal and nematode faunal composition and richness in plant litter and soil for 360 days in an area reforested with Acacia auriculiformis (A. Cunn), located in the municipality of Conceição de Macabu in the State of Rio de Janeiro. For each treatment (fertilized and unfertilized plots), samples of litter and soil (to a depth of 5 cm) were collected and transferred into a Berlese-Tüllgren funnels for the extraction of fauna. Mesofauna and macrofauna were quantified, and the major taxa identified. Nematodes were extracted by centrifugal flotation in sucrose solution and identified according to feeding habits. Density (number of individuals m-2) of total fauna, microphages, social insects and saprophages varied significantly per treatment and sampling time in both litter and soil. The total number of individuals collected was 5,127, and the total number of nematodes 894. Phosphorus and potassium fertilization resulted in an increase in total fauna density and richness in the litter due to an increased abundance of social insects, saprophages and herbivores. In the soil, fertilization increased the saprophage and predator densities. Saprophages were the predominant taxa in the litter, while social insects (Formicidae) prevailed in the soil. Litter nematode populations were favored by mineral fertilization. Bacteriophages were the predominant nematode group in both litter and soil.

Abstract:

Plant invasions may alter the soil system by changing litter quality and quantity, thereby affecting soil community and ecosystem processes. We investigated the effect of Tamarix ramosissima invasion on the decomposer fauna and litter decomposition process, as well as the importance of litter quality in decomposition. Litter decomposition and decomposer communities were evaluated in two monospecific saltcedar forests and two native forests in Argentina, in litterbags containing either local litter (saltcedar or dominant native species) or a control litter. Saltcedar invasion produced an increase in Collembola, Acari, and total mesofauna abundance, regardless of the litter type. Control litter decomposition was higher in the native forest than in the saltcedar forest, showing that increased abundance of decomposer fauna does not necessarily accelerate decomposition processes. Local litter decomposition was not different between forests, suggesting that decomposer fauna of both ecosystems is adapted to efficiently decompose the autochthonous litter. Our results suggest that the introduction of a resource with higher quality than the local one has a negative effect on decomposition in both ecosystems, which is more pronounced in the invaded forest than in the native forest. This finding stresses the low plasticity of saltcedar decomposer community to adapt to short-term environmental changes.

Abstract:

This study is a comparison of the litterfall, litter decomposition, soil macrofauna, and nutrient contents in rubber monoculture and rubber-based agroforestry plantations. The three intra-couple differences examined are rubber with pakliang (RP) compared with rubber monoculture (RMP), rubber with timber (RT) compared with rubber monoculture (RMT) and rubber with fruit (RF) compared with rubber monoculture (RMF). Rubber plantation systems were selected at 3 plantations located in nearest pairs at 18 plantations in total. Data collected included litterfall at monthly intervals from October 2016 to April 2017, as well as decomposition conditions for assessment at the end of the experimental trials. Soil samples examined the species and number of macrofaunal and decomposition measurements of mesofauna by using Lamina bait scale to analyze nutrient content. Results showed the litterfall of leaves, twinges, and fruits in rubber monoculture and rubber-based agroforestry plantations were not significant between pair comparisons. This showed leaves fell at a high incidence. However, RT experienced a higher trend in litterfall. Decomposing litterfall was also not significant between pair comparisons, but when compared by associated plant species found that RT trends were more likely to experience higher decomposition rates and the litter index was higher as well. Macrofauna in the topsoil (0-5 cm) and subsoil (5-10 cm) were not significant. The composition of mesofauna was found at high decomposition rates in RF, RP, and RT. Organic matter and nutrient contents were not significant in both soil layers. Our data emphasizes that rubber-based agroforestry plantations help regulate C and nutrient cycles, implying that external input fertilizer management requirements for rubber farmers decreased.

Abstract:

Summary Cover crops are used in Mediterranean agrosystems to reduce soil degradation and restore soil function. We carried out an experiment to test the effects of two cover crops (Brachypodium distachyon and Trifolium subterraneum, mulched or incorporated) and two bare soil controls (fertilised and unfertilised) on soil properties, biodiversity, and soil natural suppressiveness against Pratylenchus neglectus in pot microcosms. Cover crop performance, weed infestation, litter decomposition rates, soil properties, and the response of soil biota (nematode indicators, mesofauna feeding activity, enzymatic activity, and mycorrhizal spores) were measured. A short-term suppressiveness experiment was performed to determine P. neglectus colonisation of wheat roots after each treatment. Trifolium subterraneum incorporation significantly enhanced the fungal-mediated decomposition channel and decomposition rates, but enzymatic activities and mycorrhizal spore abundances did not respond to the experimental treatments. Cover crops were effective at controlling weeds, but did not increase soil suppressiveness against P. neglectus. Brachypodium distachyon cover cropping increased root infection.

Abstract:

The litter in a forest ecosystem acts as a trophic substrate, and at the same time it is the environment for litter invertebrates. But despite this fact, there has been very little research conducted on the influence of litter thickness on the structure of litter macrofauna. The litter of steppe forests contains most types of integrated communities of forest ecosystems. This means that its thickness cannot avoid playing a significant role in the functioning of the ecosystem. Following to the standard methodologies, Invertebrates were collected using pit-fall traps in deciduous forests of Nikolaev, Zaporizhzhya, Dnipropetrovsk, Donetsk and Kharkiv oblasts, which are characterized by different types of geomorphological profile, different moisture conditions, soil salinity, tree crown and herbaceous vegetation density, soil texture and other factors. The total number of macrofauna increases in conditions where litter thickness exceeds40 mmin comparison with forest ecosystems with fragmented and average capacity litter. The number of litter macrofauna species also increases from 11–23 to 38 species on average when litter thickness increases to more than40 mm. The Shannon and Pielou diversity indexes show no definite tendencies to change in relation to changing degrees of litter thickness. At sites of greater thickness of the litter layer, the corresponding increase in the absolute number of litter mesofauna invertebrates is mostly due to saprophages, and the increase the number of species – due to zoophages. The optimum structure of domination was observed at sites with maximum thickness of litter. The proportion of large species shows no statistically significant change in relation to variations in litter thickness. The qualitative compound of the fauna at sites with thick litter changes mainly due to an increase in the number of Carabidae species.

Abstract:

Tropical reforestation initiatives are widely recognized as a key strategy for mitigating rising atmospheric CO2 concentrations. Although rapid tree growth in young secondary forests and plantations sequesters large amounts of carbon (C) in biomass, the choice of tree species for reforestation projects is crucial, as species identity and diversity affect microbial activity and soil C cycling via plant litter inputs. The decay rate of litter is largely determined by its chemical and physical properties, and trait complementarity of diverse litter mixtures can produce non-additive effects, which facilitate or delay decomposition. Furthermore, microbial communities may preferentially decompose litter from native tree species (homefield advantage). Hence, information on how different tree species influence soil carbon dynamics could inform reforestation efforts to maximize soil C storage. We established a decomposition experiment in Panama, Central America, using mesocosms and litterbags in monoculture plantations of native species (Dalbergia retusa Hemsl. and Terminalia amazonia J.F.Gmel., Exell) or teak (Tectona grandis L.f.) to assess the influence of different litter types and litter mixtures on soil C dynamics. We used reciprocal litter transplant experiments to assess the homefield advantage and litter mixtures to determine facilitative or antagonistic effects on decomposition rates and soil respiration in all plantation types. Although litter properties explained some of the variation in decomposition, the microclimate and soil properties in the plantations also played an important role. Microbial biomass C and litter decomposition were lower in Tectona than in the native plantations. We observed non-additive effects of mixtures with Tectona and Dalbergia litter on both decomposition and soil respiration, but the effect depended on plantation type. Further, there was a homefield disadvantage for soil respiration in Tectona and Terminalia plantations. Our results suggest that tree species diversity plays an important role in the resilience of tropical soils and that plantations with native tree species could help maintain key processes involved in soil carbon sequestration.

Abstract:

Plant leaf litter generally decomposes faster as a group of different species than when individual species decompose alone, but underlying mechanisms of these diversity effects remain poorly understood. Because resource C : N : P stoichiometry (i.e. the ratios of these key elements) exhibits strong control on consumers, we supposed that stoichiometric dissimilarity of litter mixtures (i.e. the divergence in C : N : P ratios among species) improves resource complementarity to decomposers leading to faster mixture decomposition. We tested this hypothesis with: (i) a wide range of leaf litter mixtures of neotropical tree species varying in C : N : P dissimilarity, and (ii) a nutrient addition experiment (C, N and P) to create stoichiometric similarity. Litter mixtures decomposed in the field using two different types of litterbags allowing or preventing access to soil fauna. Litter mixture mass loss was higher than expected from species decomposing singly, especially in presence of soil fauna. With fauna, synergistic litter mixture effects increased with increasing stoichiometric dissimilarity of litter mixtures and this positive relationship disappeared with fertilizer addition. Our results indicate that litter stoichiometric dissimilarity drives mixture effects via the nutritional requirements of soil fauna. Incorporating ecological stoichiometry in biodiversity research allows refinement of the underlying mechanisms of how changing biodiversity affects ecosystem functioning.

Abstract:

The objective of this study was to improve our understanding of the role of soil invertebrates in the breakdown of litter, cycling of nitrogen, and growth of seedlings in forests of British Columbia by comparing two experimental approaches. First, in the laboratory, breakdown of birch leaves was slightly higher in the presence of millipedes in the microcosms of forest floor collected from two coastal forests. Presence of smaller animals (mesofauna) and contaminant Diptera larvae did not hasten litter breakdown in microcosms made from forest floor from either a sub-boreal or a coastal forest. In general, inorganic nitrogen release was higher in the presence of fauna, but results were highly variable. Growth of seedlings was slightly greater in the coastal microcosms that included millipedes. In the second approach, a field experiment was conducted using intact forest floor cores enclosed with one of three mesh sizes (54 µm, 1 mm, and 5 mm) and defaunated with liquid nitrogen. Comminution of birch leaves, and to some extent, greater inorganic nitrogen release occurred in sacs that allowed access to larger animals compared with sacs with fine mesh that excluded them. Although differences among treatments were small, the results from both approaches agree and indicate that soil invertebrates increase rate of breakdown of forest litter and cycling of nutrients in coastal forests.

Abstract:

Replacement of native deciduous forests by coniferous stands was a common result of former European afforestation policies and paradigms of forest management and led to considerable ecological consequences. Therefore, the most popular management strategy nowadays in multi-functional forestry is the re-establishment of mixed or broadleaved forests with native species on suitable habitats. However, our knowledge about the effects of tree species introduced into coniferous monocultures on soil mesofauna communities is scarce. We investigated abundance, species richness and diversity of Mesostigmata mite communities in decomposed litter of seven broadleaved (Acer platanoides L., A. pseudoplatanus L., Carpinus betulus L., Fagus sylvatica L., Tilia cordata Mill., Quercus robur L., Q. rubra L.) and four coniferous (Abies alba Mill., Larix decidua Mill., Picea abies [L.] Karst., Pinus sylvestris L.) species. We collected 297 litterbags after 6, 12 and 18 months of exposition in Scots pine (Pinus sylvestris) monocultures in Siemianice Experimental Forest (SW Poland). Generally, species richness and diversity in litter samples were much lower than in the soil mite pool. The highest abundance was found in P. sylvestris and A. alba litter, while the lowest was found in A. platanoides. The most abundant families were Zerconidae, Parasitidae, Veigaiidae, and Trachytidae. Our study revealed that neither species richness nor diversity were affected, but that mite abundance was affected, by the tree species (litter quality). The mite communities were similarly comprised in both high- and low-quality litter and mite abundance decreased during the decomposition process in nutrient-poor Scots pine forests. Moreover, few mite species benefited from the decomposed litter. Additionally, a litter of various tree species was inhabited mainly by eu- and hemiedaphic mite species. Mite assemblages in A. alba, P. sylvestris, and Q. robur litter had higher abundances. Exposition time seems to be an important driver in shaping the mite community during the early stages of litter decomposition.

Abstract:

AbstractForest soil and litter is inhabited by a diverse community of animals, which directly and indirectly rely on dead organic matter as habitat and food resource. However, community composition may be driven by biotic or abiotic forces, and these vary with changes in habitat structure and resource supply associated with forest land use. To evaluate these changes, we compiled comprehensive data on the species composition of soil animal communities and environmental factors in forest types varying in land-use intensity in each of three regions in Germany, i.e., coniferous, young managed, old managed, and unmanaged beech forests. Coniferous forests featured high amounts of leaf litter and low microbial biomass concentrations contrasting in particular unmanaged beech forests. However, soil animal diversity and functional community composition differed little between forest types, indicating resilience against disturbance and forest land use. Structural equation modelling suggested that despite a significant influence of forest management on resource abundance and quality, the biomass of most soil fauna functional groups was not directly affected by forest management or resource abundance/quality, potentially because microorganisms hamper the propagation of nutrients to higher trophic levels. Instead, detritivore biomass depended heavily on soil pH. Macrofauna decomposers thrived at high pH, whereas mesofauna decomposers benefitted from low soil pH, but also from low biomass of macrofauna decomposers, potentially due to habitat modification by macrofauna decomposers. The strong influence of soil pH shows that decomposer communities are structured predominantly by regional abiotic factors exceeding the role of local biotic factors such as forest type.

Abstract:

Long term applications of leguminous green mulch could increase mineralizable nitrogen (N) beneath cupuaçu trees produced on the infertile acidic Ultisols and Oxisols of the Amazon Basin. However, low quality standing cupuaçu litter could interfere with green mulch N release and soil N mineralization. This study compared mineral N, total N, and microbial biomass N beneath cupuaçu trees grown in two different agroforestry systems, north of Manaus, Brazil, following seven years of different green mulch application rates. To test for net interactions between green mulch and cupuaçu litter, dried gliricidia and inga leaves were mixed with senescent cupuaçu leaves, surface applied to an Oxisol soil, and incubated in a greenhouse for 162 days. Leaf decomposition, N release and soil N mineralization were periodically measured in the mixed species litter treatments and compared to single species applications. The effect of legume biomass and cupuaçu litter on soil mineral N was additive implying that recommendations for green mulch applications to cupuaçu trees can be based on N dynamics of individual green mulch species. Results demonstrated that residue quality, not quantity, was the dominant factor affecting the rate of N release from leaves and soil N mineralization in a controlled environment. In the field, complex N cycling and other factors, including soil fauna, roots, and microclimatic effects, had a stronger influence on available soil N than residue quality.

Abstract:

The phylum Arthropoda is one of the most diverse groups under the terrestrial surface comprising different classes of insects that occupy different environments. Some groups have a close relationship with the habitat they occupy, responding significantly to changes in the environment, thus indicating the level of change in the environment by their presence or absence. The present study aimed to demonstrate the importance of edaphic fauna as a bioindicator of environmental quality. This is a bibliographic review based on specialized consultation of scientific articles in the databases Google Scholar, SciELO-Scientific Electronic Library and ResearchGate. The studies found that environmental quality can be measured from the diversity and abundance of arthropods that live and perform their functions in the soil. Macrofauna influences important soil chemical and physical processes such as nutrient cycling, structuring and homogenization, and increased productivity, among others. The mesofauna, besides acting on soil properties, acts on the regulation of microbial populations, is sensitive to changes and responds promptly. The groups Acari, Collembola, Coleoptera, Hymenoptera and Araneae are indicated in several studies as potential bioindicators because they are commonly sampled in different environments. The factors identified as conditioning factors of the presence of these groups are environmental heterogeneity, type of vegetation cover and availability of litter, applied management system, seasonality, soil characteristics, and anthropic activities, among others. In short, because they respond quickly, the changes are considered to be efficient biological indicators; therefore, knowing the diversity of species and their degree of interaction with the environment allows us to analyze the effects of anthropic modifications in ecosystems.

Abstract:

The tea bag method provides a replicable and standardized method to study the effect of environmental variables on the decomposition of standard litter, which enables comparison of organic matter decomposition rates on a large scale. However, it remains uncertain whether tea bag decomposition in response to wetness is representative of that of local litters. We performed incubation experiments to examine whether the effect of soil water on tea bag decomposition becomes inhibitory at higher water contents, as is the case in local leaf litters. In addition, we performed field studies in a mixed forest and cedar plantation in Japan to compare two litter bag mesh sizes: 0.25-mm mesh, the size previously used by a major manufacturer of tea bags (Lipton), and nonwoven bags with mesh sizes finer than 0.25 mm, which are currently produced by Lipton. Both green tea and rooibos tea exhibited higher decomposition rates at higher water contents, but decomposition was inhibited at the highest water content; this was in contrast to our hypothesis based on a field observation but consistent with conceptual models of local litters. The nonwoven tea bags did not show lower decomposition rates, despite the finer mesh size. Rather, the nonwoven rooibos tea bags exhibited slightly higher decomposition rates than the 0.25-mm mesh bags in the cedar plantation, possibly due to a greater abundance of microorganisms that decompose litters in the nonwoven bags, due to the decrease in predation by mesofauna. Our findings provide essential information for future studies of tea bag decomposition.

Abstract:

As an important non-wood forest product and wood substitute, Moso bamboo grows extremely rapidly and hence acquires large quantities of nutrients from the soil. With regard to litter decomposition, N and P release in Moso bamboo forests is undoubtedly important; however, to date, no comprehensive analysis has been conducted. Here, we chose two dominant species (i.e., <em>Cunninghamia lanceolata</em> and <em>Phoebe bournei</em>), in addition to Moso bamboo, which are widely distributed in subtropical southeastern China, and created five leaf litter mixtures (PE100, PE80PB20, PE80CL20, PE50PB50 and PE50CL50) to investigate species effects on leaf litter decomposition and nutrient release (N and P) via the litterbag method. Over a one-year incubation experiment, mass loss varied significantly with litter type (<em>P</em> < 0.05). The litter mixtures containing the higher proportions (≥80%) of Moso bamboo decomposed faster; the remaining litter compositions followed Olson’s decay mode well (<em>R</em><sup>2</sup> > 0.94, <em>P</em> < 0.001). N and P had different patterns of release; overall, N showed great temporal variation, while P was released from the litter continually. The mixture of Moso bamboo and Phoebe bournei (PE80PB20 and PE50PB50) showed significantly faster P release compared to the other three types, but there was no significant difference in N release. Litter decomposition and P release were related to initial litter C/N ratio, C/P ratio, and/or C content, while no significant relationship between N release and initial stoichiometric ratios was found. The Moso bamboo–<em>Phoebe bournei</em> (i.e., bamboo–broadleaved) mixture appeared to be the best choice for nutrient return and thus productivity and maintenance of Moso bamboo in this region.

Abstract:

Abstract. Crop residues are valuable soil amendments in terms of the carbon and other nutrients they contain, but the incorporation of residues does not always translate into increases in nutrient availability, soil organic matter (SOM), soil structure, and overall soil fertility. Studies have demonstrated accelerated decomposition rates of chemically heterogeneous litter mixtures, compared to the decomposition of individual litters, in forest and grassland systems. Mixing high C:N ratio with low C:N ratio amendments may result in greater carbon use efficiency (CUE) and nonadditive benefits in soil properties. We hypothesised that nonadditive benefits would accrue from mixtures of low-quality (straw or woodchips) and high-quality (vegetable waste compost) residues applied before lettuce planting in a full factorial field experiment. Properties indicative of soil structure and nutrient cycling were used to assess the benefits from residue mixtures, including soil respiration, aggregate stability, bulk density, SOM, available N, potentially mineralisable N, available P, K, and Mg, and crop yield. Soil organic matter and mineral N levels were significantly and nonadditively greater in the straw–compost mixture compared to individual residues, which mitigated the N immobilisation occurring with straw-only applications. The addition of compost significantly increased available N, K, and Mg levels. Together, these observations suggest that greater nutrient availability improved the ability of decomposer organisms to degrade straw in the straw–compost mixture. We demonstrate that mixtures of crop residues can influence soil properties nonadditively. Thus, greater benefits may be achieved by removing, mixing, and reapplying crop residues than by simply returning them to the soils in situ.
