Soil macrofauna of primary forests of the middle taiga is characterized by high abundance (94.6–146.6 ind./m2), taxonomic richness (10–14 taxa), dominance of Diptera and Cantharidae larvae, similarity of fauna composition (J=0.60–0.65), with a ratio of detritivores and predators equal to 1:1, aggregated or random horizontal distribution. The total density of invertebrates sharply decreases (4.5–26.8 ind./m2) in the first year after deforestation. Some taxa are eliminated from the fauna, 4–7 taxa are remained. The ratio of trophic groups is changed. The distribution of invertebrates in space is disturbed. Soil macrofauna of clear-cutting areas (CCA) retains a taxonomic structure close to the control sites (C). The taxonomic and trophic structure of soil macrofauna is more disturbed on the logging corridors (LC) with three (3LC) and ten (10LC) penetrations of aggregate equipment, recultivated (RLC) and main (MLC) logging corridors. Thus, the density of Diptera larvae is high on the logging corridors. The above are temporary r-strategists characteristic for the disturbed environment. And the ratio of detritivores and predators on the technological sites “C – CCA – 3LC – 10LС – RLC – MLC” is 1:1 – 3:1 – 7:1 – 10:1 – 13:1 – 15:1. A trend towards an increase in the density of detritivores on the recultivated (RLC) and main (MLC) logging corridors was noted. The decrease of the total density of macrofauna and the declining of systematic groups of the clear-cutting areas is not so significant due to the fact that the litter on these sites is almost completely preserved after felling. The low diversity of soil macrofauna on the logging corridors can be explained by a change in the natural conditions for the existence of invertebrates due to the compaction of the upper soil horizons, the partial disappearance of the litter, the appearance of a mineralized soil layer as top horizon, and a rapid change in humidity. Significant changes in the abundance, composition, and ratio of trophic groups of invertebrates indicate the collapse of soil macrofauna, the loss of important groups of destructors and predators from food webs, and a decrease in the quality of their functions at the initial stage of restorative succession, in the first year after deforestation.

Soil macrofauna diversity and biomass associated with the “fertility islands” beneath oak trees in a semi-arid woodland

Fertility islands are patches of soil beneath the trees and shrub's canopy and contain higher nutrient availability and water content than the surrounding areas in arid and semi-arid lands. Fertility islands are home to various soil organisms that play a crucial role in nutrient cycling. This study aimed to determine the influence of fertility islands beneath the coppiced oak trees on soil macrofauna diversity and biomass in semi-arid oak woodland. For this purpose, two main microhabitats, including beneath the patches of oak sprout-clumps (BPSC) and the interspaces (SBSC), were considered. Each microhabitat was divided into four classes with respect to the number of sprouts per sprout-clumps (N = 1–3, N = 3–10, N = 10–20, and N > 20) and distance gradient from the canopy (D = 0 m, D = 1–3 m, D = 3–5 m, and D > 5 m). Soil physical and chemical properties, soil macrofauna taxonomic group diversity, and biomass were measured for each microhabitat class. Most of the soil's physical and chemical properties, such as soil litter, soil organic carbon (SOC), available phosphorus (P), moisture content, and electrical conductivity (EC), were higher in BPSC than in SBSC. These properties were influenced by the structure (number of sprouts) of oak sprout-clumps and the distance gradient from the canopy. Soil macrofauna individuals (density), biomass, and diversity were higher in BPSC than in SBSC. A significant difference in soil macrofauna groups composition was found only at the canopy edge and was not affected by increasing distance from the canopy. The soil macrofauna diversity was positively correlated with soil moisture, SOC, and P. It was concluded that the sprout-clumps' structure influences the quality of fertility islands beneath the oak sprout-clumps and consequently dictates the variation of soil macrofauna composition and biomass.

Diversity of soil macrofauna in traditional oil mining of Wonocolo Geosite, Bojonegoro Geopark, East Java, Indonesia

Abstract. Rahmawati LA, Afiati N, Putranto TT. 2024. Diversity of soil macrofauna in traditional oil mining of Wonocolo Geosite, Bojonegoro Geopark, East Java, Indonesia. Biodiversitas 25: 2148-2160. Wonocolo traditional oil mining has been going on for 130 years and has led to soil pollution. This study aims to characterize the composition of macrofauna in the soil affected by Wonocolo's traditional oil mining. The existence of macrofauna is important as a bioindicator of soil quality and its role in maintaining soil fertility levels. Mining areas are grouped based on the density of the oil well (rare, medium and dense), then three sample points are selected in each group. Macrofauna were collected using quadrat-hand sorting, pitfall trap, and flannel trap methods, and then the community structure index was analyzed. The results showed that 709 individuals were collected consisting of 17 orders and 71 species, with 64.8% of individuals found in category-dense areas. Hymenoptera and Polyrhachis sp. as the most abundant order and genus, while Odontomachus brunneus Patton 1894 is the most frequently encountered species. The average value of biodiversity, dominance, and evenness index ranged H'=1.28-1.57 (low), C=0.29-0.38 (low), and E=0.78-0.90 (high), respectively. Indications of environmental conditions in traditional oil mining areas cannot be seen solely from the value of the macrofauna biodiversity index but are apparent in the abundance of the Hymenoptera order in all areas categories and significant presence of Polyrhachis sp. species in the dense category.

The relation of macrofauna and soil organic carbon in Sacha Inchi cropping patterns

Abstract Soil macrofauna plays an important role in the soil ecosystem. Through various biological activities, macrofauna provides various ecosystem services such as the provision and regulation of nutrients and carbon through litter decomposition, increasing water holding capacity, and improving soil structure. The diversity of soil macrofauna is strongly influenced by the litter produced. The more diverse types of plants, the more diverse macrofauna will be found. The purpose of this study was to determine the relationship between macrofauna and soil organic carbon in various cropping patterns of sacha inchi in Sragen, Central Java. The research was conducted on teak-sacha inchi, teak monoculture, mixed agroforestry, and sacha inchi monoculture. Based on the results, there were a total of 6 orders of macrofauna in four types of cropping patterns. The highest total number of individuals was found in the sacha inchi monoculture. The macrofauna diversity index was found the highest in teak-sacha inchi with a Shannon-Wiener index of 1.207, and the lowest in the sacha inchi monoculture with a Shannon-Wiener index of 0.76. Based on the correlation analysis, it is known that soil organic carbon content has a negative correlation with the number of macrofauna and a positive correlation with macrofauna diversity.

Distribution of Soil Macrofauna Diversity and Abudance Land Used at Moving Agricultura Systems Warmare District, Regency of Manokwari, Province of West Papua

Warmare District, Manokwari Regency, West Papua Province is one of the areas where the people still maintain the shifting cultivation system and it has even become one of the local wisdoms in the area. This research aims to examine the diversity and density of soil macrofauna on shifting cultivation land in the Warmare District, Manokwari Regency. The method used in this research is the direct handsorting method in the field and macrofauna identification using a binocular microscope. Data analysis used in this research was cluster analysis with PAST (Powerful Software for Scientific Data Analysis) software version 3.4 and used the Landmarks 3D PCA test to see the relationship between soil macrofauna diversity and land use types. The research results showed that the highest density and diversity of soil macrofauna was shown by the use of forest land with 38 taxa at a depth of 0-10 cm and 37 taxa at a depth of 10-20 cm. Where the high diversity composition of the Shannon-Weaner index is shown by forest land use with a value of 0.94 and is reinforced by the low Simpson index value of 0.30 for forest land use. This is in line with the results of the PCA analysis which shows that macrofauna forest land is compared with monoculture cultivation land and polyculture cultivation land.

Runoff and soil loss are drastically decreased in a rubber plantation combining the spreading of logging residues with a legume cover

Soil erosion on agricultural land is a major threat for food and raw materials production. It has become a major concern in rubber (Hevea brasiliensis) plantations introduced on sloping ground. Alternative agroecological crop management practices must be investigated. One aim of our study was to assess the ability of logging residues (i.e., trunks, branches, leaves and stumps of a clearcut plantation) and of legume cover (Pueraria phaseoloides) to mitigate N, P and K losses through runoff and soil detachment in a young rubber plantation. The other aim was to investigate the relationships of these nutrient losses with soil structure and soil macrofauna diversity. Runoff and soil loss were monitored for 3 years using 1-m2 plots under different practices as regards the management of logging residues and the use or not of a legume. The monitoring started when rubber trees were one-year-old. The planting row, where soil was bare, was the hotspot of soil erosion, with an average runoff of 832 mm y−1 and soil loss of 3.2 kg m−2 y−1. Sowing a legume in the inter-row reduced runoff and soil loss by 88 % and 98 % respectively, compared to bare soil. Spreading logging residues as well as growing a legume cover almost eliminated runoff and soil detachment (19 mm y−1 and 4 g m−2 y−1 respectively). Nutrient losses were negligible as long as the soil surface was covered by a legume crop, with or without logging residues. Total N loss from soil detachment ranged from 0.02 to 0.2 g m−2 y−1, for example. Spreading logging residues in the inter-rows significantly improved soil structure and soil macrofauna diversity compared to bare soil. Nutrient losses from runoff and soil detachment were negatively correlated with improved soil structure and soil macrofauna diversity. We recommend investigating alternative ways to manage planting rows.

Soil macrofauna diversity and weed dynamics in response to different methods of weed control in smallholder rubber farming

Abstract. Chaniago I, Yulistriani, Umami IM, Bukhari ZZ. 2023. Soil macrofauna diversity and weed dynamics in response to different methods of weed control in smallholder rubber farming. Biodiversitas 24: 3106-3113. Weeds interference in rubber farmland may reduce latex yield. Farmers apply herbicides to control weeds. However, the herbicide not only controls weed but also affects the presence of soil macrofauna. A study has been conducted to determine the effect of different method of weed control on soil macrofauna and weeds at smallholder rubber farming at Pulau Punjung, Dharmasraya District, West Sumatra, Indonesia. The experiment was conducted in a completely randomized block design with 6 treatments and 4 pseudo-replications. Treatment was mechanical control, without weed control, and 4 doses of herbicide glyphosate+metsulfuron-methyl (1.5 L ha-1 + 15 g ha-1, 2 L ha-1 + 15 g ha-1, 2.5 L ha-1 + 15 g ha-1, 3 L ha-1 + 15 g ha-1) with 400 L ha-1 of volume. Pitfall traps were used to collect the soil macrofauna. Data were analysis with ANOVA for weed and soil macrofauna in response to different methods of weed control. Results demonstrated that the application of glyphosate+metsulfuron-methyl herbicide significantly suppressed weeds higher than that of other methods of weed control (p<0.05). Para grass (Brachiaria mutica (Forssk.) Stapf) was the most dominant weed but has been affected most by 3 L ha-1 + 15 g ha-1 herbicide mixture. Soil macrofauna of the order Hemiptera was affected most by the application of herbicide with a total reduction of 71.58% of number of individuals at 12 weeks after application of herbicide. In general, different weed control methods resulted in varied numbers of orders and individuals of the soil macrofauna.

The role of soil and plant cover as drivers of soil macrofauna of the Dnipro River floodplain ecosystems

Abstract Floodplain ecosystems are hotspots of biological diversity and perform important ecosystem functions in the landscape. The key to understanding the sustainability of ecosystem function is knowledge of the relationships between ecosystem components. The article reveals the role of morphological and physical properties of soil, as well as phytoindication of environmental factors as drivers of biological diversity of soil macrofauna of protected ecosystems of the Dnipro River floodplain. The studies were conducted in the forest floodplain ecosystems of the “Dnipro-Orilskiy” Nature Reserve. The studies of morphological properties of soils allowed us to identify the representatives of two reference groups: Fluvisol and Gleysol. The soil physical property data were subjected to principal component analysis, which extracted four principal components whose eigenvalues exceeded unity and described 79.9% of the variation in traits. The principal components of variation in soil physical properties and phytoindication assessments of environmental factors were used as predictors of the community structure of soil macrofauna. These predictors were able to explain 29.6% of the community variation. Physical soil properties are most important as a driver of soil macrofauna. The morphological properties of the soil and phytoindicator assessments are able to explain a much smaller part of the community variation. The pure influence of the predictors is small, indicating that they interact significantly in influencing soil animals. The results obtained have implications for the development of optimal strategies for floodplain ecosystem management and biodiversity conservation.

The results showed that types of soil macrofauna in Forest Areas Education and Training Sisimeni Sanam especially under the stands of forest habitat heterogeneous and homogeneous forest consists of 11 ordo with a total of 1,113 individuals were found. The diversity level of soil macrofauna under heterogeneous and homogeneous forest habitat stands at 1.71063 and 0.55568. The level of similarity between soil macrofauna under heterogeneous forest habitat stands is high with an average value of 62.406%.

Community Characteristics and Niche Analysis of Soil Animals in Returning Farmland to Forest Areas on the Loess Plateau

Niche theory is significant for understanding the function of community structure, interspecific relationships, and community dynamic succession. However, there are few studies on the soil animal niche in returning farmland to forest areas on the Loess Plateau, making it challenging to comprehend the utilization of soil animal resources, the stability of the local community, and the succession process in the areas. Therefore, this study collected soil animals in five typical vegetation types: Robinia pseudoacacia (R), Hippophae rhamnoides (H), Populus simonii (P), Pinus tabulaeformis (T), and Armeniaca sibirica x Hippophae rhamnoides (M), with abandoned grassland (G) used as a control group. Then, the number of soil animal taxa, individuals, diversity, and niche were sampled and examined in the study areas during the four seasons of spring, summer, autumn, and winter using the manual sorting method and the Tullgren method. The results revealed that 3872 soil animals from 3 Phyla, 8 Classes, 22 Orders, and 49 Families were captured in the study areas. The dominant groups of soil macrofauna were Diptera larvae, Julidae, and Formicidae, and the dominant groups of meso–micro soil fauna were Oribatida, Protospira, and Collembola juveniles. Soil animals have rich nutritional function groups, with the most saprophytic soil animal groups. The individual density and taxa number of soil animals in G were lower than other vegetation on the whole. H, M, and P had a higher Shannon–Winner index than the other vegetation. Seasonal changes had different effects on macro and meso–micro soil fauna. The diversity of soil macrofauna is higher in spring and summer, and that of meso–micro soil fauna is higher in autumn and winter. Oribatida, Diptera Larvae, and Formicidae had a large niche width in the main taxa of soil animals, with universal adaptability to the environment. Cicadellidae and Culicidae had narrow niche widths and were highly dependent on resources and the environment. There were 67 pairs of highly overlapped (Oik > 0.8) taxa of soil animals and 56 pairs of moderately overlapped (0.6 < Oik ≤ 0.8) taxa, accounting for 80.39% of the total number of taxa. Soil animals had high commonality in resource utilization, intense competition, and poor community stability. As a result, we can conclude that the soil animal community in the study areas was in the stage of succession.

Soil Macrofauna Diversity and Litter Decomposition Rate in the Buffer Zone of Lore Lindu Biosphere Reserve Indonesia

Conversion of forest to agricultural land (agroforestry and monoculture) has a negative impact on soil macrofauna diversity. Soil macrofauna have a key role in maintaining soil fertility through decomposition and supporting the productive capacity of ecosystems. This study aimed at determining the soil macrofauna diversity and the litter decomposition rate in agroforestry and monoculture and investigating the correlation between soil macrofauna diversity and litter decomposition rate. This study involved field and laboratory activities. Litter traps were installed for soil macrofauna observation, macrofauna identification was carried out in the laboratory, and litter bags were used for decomposition rate observation. Data analysis was conducted to determine species diversity and similarity of soil macrofauna on agroforestry and monoculture plantations. The calculation of the diversity index (H’) shows that complex agroforestry and simple agroforestry have moderate, while candlenut monoculture has low diversity of soil macrofauna. The similarity of soil macrofauna in these sites is low (similarity index below 50%). The decomposition rate of litter is relatively high (0.01 g/day). The correlation between species diversity and the decomposition rate of litter in complex agroforestry and candlenut monoculture is very strong. Meanwhile, in simple agroforestry, the correlation is relatively low.

Tree-based land uses enhance the provision of ecosystem services in agricultural landscapes of the Peruvian highlands

Trees can have important impacts on multiple ecosystem services and biodiversity in agricultural landscapes. The influence of trees can extend beyond forested areas and into adjacent land uses, however, this is rarely accounted for in the ecological literature. To better understand the influence of trees in Andean agroecosystems, we examined alternative landscape scenarios in the community of Quilcas (Junín, Peru), where we explored the potential impact of replacing tree-based land uses (with crops and pasture) on landscape carbon (C) storage and soil biodiversity (soil macrofauna and ground vegetation). Additionally, we estimated the influence of tree-based land uses on soil C storage (0–20 cm depth) and macrofauna diversity in adjacent croplands and pastures. Tree-based land uses were dispersed across the landscape and occupied 26 % of the area, including a mix of forest patches, plantations, and hedgerows. Given that above- and belowground C stocks were generally higher in land uses with trees versus those without, the inclusion of trees in this landscape is estimated to increase the total landscape C storage by 153 %. Macrofauna diversity also varied across different land uses, being highest in alder (Alnus acuminata) forests and hedgerows, such that the inclusion of trees enhances overall macrofauna diversity (Shannon Index) by 25 % but appears to have a slightly negative effect (−6 %) on ground vegetation diversity. When accounting for the influence of trees on adjacent land uses, estimates for overall soil C storage at the landscape scale increased by 1.4 %, while macrofauna diversity increased by approximately 5 %. Our findings indicate that the addition of trees can greatly enhance overall C stocks and soil macrofauna diversity in agricultural landscapes, and that it is important to consider spatial interactions between land uses to fully quantify and optimize these interactions.

Revealing the millipede and other soil-macrofaunal biodiversity in Hong Kong using a citizen science approach.

Soil biodiversity plays important roles in nutrient recycling in both the environment and agriculture. However, they are generally understudied worldwide. To reveal the diversity of soil macrofauna in Hong Kong, here we initiated a citizen science project involving university, non-governmental organisations and secondary school students and teachers. It is envisioned that the citizen science approach used in this study could be used as a demonstration to future biodiversity sampling and monitoring studies. Throughout a year of monitoring and species sampling across different localities in Hong Kong, 150 soil macrofaunal morphospecies were collected. Eighty five of them were further identified by morphology and DNA barcoding was assigned to each identified morphospecies, yielding a total of 646 DNA barcodes, with new millipede sequences deposited to the GenBank. The soil macrofauna morphospecies in Hong Kong found in this study are mainly dominated by millipedes (23 out of 150) and oligochaetes (15 out of 150). Amongst the twenty three identified millipedes, two polyxenid millipedes, Monographisqueenslandica Huynh & Veenstra, 2013 and Alloproctoidesremyi Marquet and Condé, 1950 are first recorded in Hong Kong. Information has been curated on an online platform and database (http://biodiversity.sls.cuhk.edu.hk/millipedes). A postcard summarising the findings of millipedes in Hong Kong has also been made as a souvenir and distributed to citizen participants. The identified macrofauna morphospecies and their 646 DNA barcodes in this study established a solid foundation for further research in soil biodiversity.

Illuminating biodiversity changes in the ‘Black Box’

Soil is often described as a ‘black box’, as surprisingly little is known about the high levels of biodiversity that reside there. For aboveground organisms, we have good knowledge of the distribution of the species and how they might change under future human impacts. Yet despite the fact that soil organisms provide a wide variety of ecosystem functions, we have very limited knowledge of their distribution and how their diversity might change in the future. In order to create accurate and generalisable models of biodiversity, the underlying data need to be representative of the entire globe. Yet even with our recently compiled global earthworm dataset of over 11000 sites, there are gaps across large regions. These gaps are consistent across many other datasets of both above- and belowground diversity. In order to fill the gaps we propose a sampling network (SoilFaUNa), to create a comprehensive database of soil macrofauna diversity and soil functions (e.g. decomposition rates). Building on the existing dataset of earthworm diversity and early data from the SoilFaUNa project, we will investigate changes in earthworm diversity. From our current work, we know that both climate and land use are main drivers in predicting earthworm diversity, but both will change under future scenarios and may alter ecosystem functions. We will, using space-for-time substitution models, estimate how earthworm diversity and their functions might change in the future, modelling earthworm diversity as a function of climate, land use and soil properties and predicting based on future scenarios. Previous studies of aboveground diversity changes over time using time-series analysis have found no-net-loss in richness, but analyses have criticisms. We aim to use time-series data on earthworms to move this debate forward, by using data and statistical methods that would address the criticisms, whilst increasing our knowledge on this understudied soil group. Field experiments and micro-/mesocosm experiments have been used to investigate the link between a number of soil organisms and ecosystem functions under few environmental conditions. Meta-analyses, which can produce generalisable results can only answer questions for which there are data. Thus, we have been lacking on information on the link between the entire community of soil fauna and ecosystem functions and impact of changes to the soil fauna community across environmental contexts. Using data collected from the SoilFaUNa project, we will, for the first time, synthesise globally distributed specifically-sampled data to model how changes in the community composition of soil macrofauna (due to changes in land use, climate or soil properties) impact the ecosystem functions in the soil.

Diversity and function of soil macrofauna: key information for studying the sustainability of tropical social-ecological systems

The biological diversity is a natural inherent element of social-ecological systems. Within the great species diversity there is a group of small invertebrates (2–20 mm), inhabiting terrestrial soils and aquatic sediments, known as macrofauna. Contrary to its name indicates, the macrofauna is generally overlooked, poorly represented in biological inventories or management programs, and not contemplated in any political agenda, but they consist of high number and many groups of species with a high diversity in shapes and functions. Knowing this diversity and their functions in both terrestrial and aquatic habitats is fundamental to understand its role within the social-ecological systems, by giving key information that would advance our comprehension on the role of macrofauna in the quality of environmental services provided by ecosystems. Furthermore, this understanding is crucial due to the fact that the macrofauna is threatened by anthropogenic activities, which could lead to local modifications in the processes that take place in the soil. Therefore, the purpose of this work is, in general, to make known to the reader the main species groups that integrate the macrofauna, the equivalent functional role that these organisms play in the terrestrial and aquatic habitats where they occur, as well as their importance in studies of sustainability in tropical social-ecological systems.

IDENTIFIKASI DIVERSITAS MAKROFAUNA TANAH DI AREA TAMBANG PANAS BUMI MUTUBUSA DESA SOKORIA KECAMATAN NDONA TIMUR

Soil macrofauna is animals that have a body size of 2-20 mm. The main place of life for macrofauna is not only above but also underground. The purpose of this study was to determine the diversity of soil macrofauna and environmental conditions on forest land and agricultural land in the Mutubusa Geothermal Mine area. The selection of research sites using the purposive sampling method and The sampling technique was carried out by the monolith sampling method. Observational variables in this study were diversity index, relative frequency, density index, and relative density. The results of the diversity analysis show that there are ten types of soil macrofauna, that is; Cockroaches, Millipedes, Spiders, Ants, Conch, Earthworms, Crickets, Grasshoppers (H' = 1.67), Mixed Fields (H' = 1.32), and Coffee Fields (H' = 1.28). While the density of soil macrofauna in candlenut land is 2.9%, forest land is 0.2%, mixed land is 1.5% and coffee land is 0.4%. The highest important value index in candlenut land was snail species, amounting to 39%, while in forest and mixed land, the highest important value index was ant species, respectively, 41% and 67%.

Land-use intensification reduces soil macrofauna biomass at the community but not individual level

Land-use intensification and climate change are main threats to the abundance and diversity of soil macrofauna. However, little is known about their biomass in response to these concurrent drivers. Here, we investigated the biomass responses of soil macrofauna along a land-use intensity gradient of five land-use regimes (i.e., from extensively-used grassland to conventional cropland) under two climate scenarios (ambient vs. future). We found that land-use intensification (but not climate change) significantly reduced soil macrofauna biomass at the community rather than individual level. Further, the community structure of soil macrofauna based on total biomass data varied with land-use type (i.e., grasslands vs. croplands). Collectively, our findings suggest that land-use intensification can negatively shift the community biomass patterns of soil macrofauna consistently under both ambient and future climates in agroecosystems.

SOIL MACROFAUNA AND MESOFAUNA COMMUNITY ON AGRICULTURAL LAND IN PLIKEN VILLAGE, KEMBARAN DISTRICT, BANYUMAS REGENCY

Soil is a habitat for various types of fauna, especially macrofauna and soil mesofauna. In general, fertile soil can be found on land used for agricultural activities. The purpose of this study was to determine and reveal the community structure of soil macrofauna and mesofauna which includes individual count, diversity, and dominance as well as environmental quality on agricultural land in Pliken Village, Kembaran District, Banyumas Regency in 2021. The study was carried out in January-June 2021. by using survey method and purposive random sampling technique. Sampling of soil macrofauna and mesofauna was carried out in three locations, namely agricultural land in the west, north, and south of the village. Data sampling was carried out in the morning (07.00-09.00 am) and at night (19.00-21.00 am) 6 times with an interval of once a month. Soil macrofauna and meofuana that had been obtained were identified using the Taxonomy and Identification Key book. An Introduction to the Study of Insects and other references related to the identification of soil macrofauna During the study, 2717 soil macrofauna were found which belong to 15 Orders, 31 Families and 40 Species, while for soil mesofauna, 500 individuals were obtained which belong to 14 Orders, 18 Families. and 21 species.The highest individual count for soil macrofauna came from the Formicideae family (86.86%), while the highest individual count for soil mesofauna came from the Isotomideae family (27%). The index of soil macrofauna diversity on agricultural land in Pliken Village ranged from 0.997- 1,789 with an average of 1,287 which means the level of diversity is moderate, while the index Soil mesofauna diversity ranges from 1.13 to 2.15 with an average of 1.65 which means the level of diversity is moderate. Soil macrofauna dominance index is moderate with a range of 0.264 - 0.546 which indicates that there is still dominance by certain soil macrofauna, namely the Formicideae (ant) family, while the soil mesofauna dominance index ranges from 0.13 to 0.38 with an average of 0.23 which indicates the absence of a predominant species. The environmental quality of agricultural land in Pliken Village is categorized as good to support the life of macrofauna and soil mesofauna.
