These farmers have to choose sustainable land use management practices for their survival in the region and, for soil and forest conservation. The study area is located in the Piranheira Praialta Agroextrativist Settlement Project in the county of Nova Ipixuna, Pará, Brazil. The objective of this research is to understand the relations between soil physical, chemical and biological attributes, and how these relations change with modifications in land use. This information is important for defining best management practices for family farming in the region. Two toposequences were chosen, one under native forest and the other under pasture. 40 cm pits were opened with five replicates in three landscape positions (upslope, midslope and downslope). Sampling periods were July/2012 (dry season); January/2013 (beginning of rainy season) and march/2013 (rainy season). Samples were taken for soil particle size analysis, bulk density, particle density, moisture, porosity, water retention, chemical, litter dry matter and macrofauna analysis. Statistical analysis techniques were performed uni and multivariate. No significant differences were observed in the particle size distribution of the studied soils. The soils presented sandy surface horizons with an increase of clay in depth in both land use systems. Soil bulk density values were higher in the surface horizons and, in general, in the pasture toposequence. Differences were also observed in the soil moisture content and litter dry matter which were higher under the native forest, and in the pH and organic matter values which were higher in the pasture. Higher water retention capacity was observed in the surface horizons of the forest when compared to the pasture, corroborating the higher values of macroporosity observed in the forest soils. Due to higher moisture content, litter dry matter, water retention capacity and macropores present in the soils under native forest, a higher diversity and richness of macrofauna species was observed in the forest soils when compared to the pasture. Apart from the higher diversity, exclusive species and individuals with a larger body diameter were also found in the forest. A more detailed analysis of the earthworms, indicates a higher quantity of individuals under pasture, but these have smaller body diameters than the individuals found under the forest. The presence of individuals with larger body diameters influences the development of macropores in the forest surface horizons. Analyzing the influence of macrofauna on the different soil attributes, few changes were observed in the superficial horizons in relation to soil bulk density and total porosity in both land use systems. On the other hand, differences in the size and distribution of pores by the macrofauna were observed. These changes influence directly the soil water dynamics altering, sometimes irreversibly, the soil functioning in different land use systems.

In the agricultural soils of the Pampa region of Argentina, earthworms are undoubtedly the key soil ecosystem engineers. Indeed, earthworms are involved in building and maintenance of porosity through bioturbation and burrowing; comminution, selection and or activation of microflora activities and in soil formation, by bioturbation, cast deposition and particle selection. Attending to the importance of such processes to preserve the soil capacity to sustain crop productivity, the promotion of suitable habitats for earthworm communities, has become a main goal for sustainable agriculture. However, in Argentine Pampas, the impact of the huge amount of pesticides currently spread on farming soils, on the earthworm biology and ecology, is scarcely considered when agricultural managements practices are selected. In fact, more tha...

This process has led to soil physical, chemical and biological degradation in those systems. The increase of crop rotation rates in no-till and reduced tillage systems has been proposed as an alternative with reduced negative impact on soils in the context of conventional agriculture. On the other hand, extensive organic farming is also suggested as an alternative to high-input agriculture systems. In this article, we aim to explore how different variations of farming practices and systems impact soil macrofauna, along an edaphoclimatic gradient in the Pampas region. We studied the following systems: natural grassland (Gr) as indicator of the original community, extensive organic farming (Org), conventional agriculture with no-tillage and three crop rotation levels (Nt-R1, Nt-R2 and Nt-R3), and reduced tillage with two levels of crop rotation (Til and Til-R). We assessed soil macrofauna, with emphasis on earthworm, beetle and ant communities; and soil physical and chemical properties. Macrofaunal taxa composition was significantly affected by both management systems and edaphoclimatic conditions. The Gr community had pronounced differences from all the agricultural systems. The earthworm community from Gr had distinctive features from those of most agricultural systems, with Org and Nt-R3 being the most similar to Gr in native and exotic earthworm species, respectively. The beetle community in Org was the most different one, and the communities from the other systems did not show a pattern related to management. Ant community composition was not determined by management systems, but it was affected by edaphoclimatic conditions. All the studied macrofauna groups had a significant co-variation with soil physical and chemical properties, showing that both the characteristics of each soil relative to the geographic location and the effect of management on abiotic soil attributes have an important effect on soil macrofauna. This study confirms that biodiversity is being lost in Pampas soils, which implies a possible threat to the soil capacity to perform the processes that sustain soil functioning and hence plant productivity. Further considerations about the sustainability of the current agricultural model applied in the Argentine Pampas are needed.
Earthworm and Enchytraeid Co-occurrence Pattern in Organic and Conventional Farming

We investigated if different agricultural managements produce a replacement of earthworms by enchytraeids, the magnitude of that replacement, and its effect on ecosystem engineering activities. Organic farming with plough tillage (ORG), conventional farming with plough tillage, conventional farming with no-tillage (NT), and unmanaged natural grasslands were studied. Earthworms and enchytraeids were sampled by means of extracting and hand sorting soil monoliths. Soil bulk density, mechanical resistance, organic matter content, and litter decomposition were measured as indicators of soil structure maintenance and nutrient cycling. A negative relation between earthworm and enchytraeid abundances was confirmed, not related to tillage intensity. Competitive interactions between them are suggested. Among agricultural systems, ORG had the highest earthworm abundance and NT had the highest enchytraeids abundance and the highest enchytraeid-to-earthworm ratio. Besides, intermediate abundances of earthworms and enchytraeids promoted by ORG were related to soil structure indicators' values similar to grassland and enhanced litter decomposition process. Despite a higher abundance of enchytraeids in NT, both soil structure maintenance and nutrient cycling indicators had worse values than those in ORG.

This study evaluated the effects of forest conversion to pasture on soil attributes and how the changes on the earthworm community affect soil porosity. Soil samples were collected from two toposequences (forest and pasture) at the summit (T1), midslope (T2) and footslope (T3) positions in July 2012 (dry season) and January and March 2013 (wet season). Samples were taken in five replicates at the depths of 0 to 10, 10 to 20, and 20 to 30 cm for determination of moisture, bulk density, total porosity, micromorphometry of pores, surface litter dry matter, chemical properties, and abundance and richness of earthworms. The numbers of macropores and micropores and S index (S) were calculated. The change on land use increased soil organic matter, pH, and calcium and reduced dry matter, moisture, and S index in pasture, as well as the loss of earthworm morphospecies highly related to the maintenance and formation of soil macroporosity, especially large rounded pores and, secondarily, large complex pores. This resulted in a loss of soil physical quality.

However, several concerns remain about its conservative nature, especially when it is performed either without cover crops or appropriate rotation schedules, and when it is accompanied by the usage of high amounts of agrochemicals. In this paper, we study some soil quality parameters when NT is adopted instead of reduced tillage, as well as the relevance of soil physical and chemical properties to explain the impact of management systems on soil macrofauna. We compared NT and reduced tillage (RT) systems, using natural grasslands (GR) as reference. We hypothesised that (1) soil quality will decline in both agricultural systems compared to the grassland but this declination will be less in no-till than in reduced tillage, and that (2) the changes in macrofauna community could be explained by changes in physical and chemical soil properties. Soil cover, organic matter, pH, moisture content, bulk density and mechanical resistance were assessed as indicators of soil physical and chemical quality. Soil macrofauna abundance and composition was determined by the TSBF method. We rejected our first hypotheses since from the assessed parameters only soil moisture content and spider abundance were favoured in NT compared to RT. Changes caused by both systems in the macrofauna composition (especially in soil inhabitants) were mainly explained by soil physical and chemical attributes. The ordination of sites according to canonical correspondence analyses clearly shows the influence of the management systems in the relationship between macrofauna assemblages and soil physical and chemical parameters; especially in the upper 30 cm of soil. GR had both a better soil physical and chemical quality and a higher abundance of the main macrofauna taxa (earthworms, beetles and ants) compared to agricultural systems. NT and RT were similar, sharing low earthworm and ant abundance and high potworm abundance. Our results show that adopting NT instead of RT does not favour assessed soil quality parameters. Thus, NT is questioned as a system which enhances soil quality, at least in the way it is performed by most farmers from Argentine Pampa. 2015 Elsevier B.V. All rights reserved.

A group of farmers started to use the Good Agricultural Practices (GAP) which include a higher crop rotation, use of winter cover crops and nutrient restoration. In this NT system earthworms have a significant role in soil functioning, particularly in organic matter cycling and soil structure formation. The aim of this paper was to examine the contribution of earthworm activity to the process of C incorporation and soil structure maintenance in soils with different NT variants of: NT with GAP for 30 years (NT + r30); NT with some of the GAP for 12 years (NT-r12) and NT with soybean monoculture (NTm). Also a natural grassland (NA) was sampled as a reference. Earthworm aggregates were obtained by gently separating them from surrounding soil. Fine (HOC) and coarse (POC) organic matter fractions, water-stable aggregates (WSA) and mean weight diameter (MWD) were calculated for earthworm aggregates and bulk soil. In all sites only one species (Aporrectodea caliginosa) was found, with higher density in the NA, followed by NT + r30, that had about 9 times more earthworms than NTm. The number of earthworm aggregates was higher in the NT + r30 followed by the NA, both showing differences with the other NT systems. The earthworm aggregates in NA and NT + r30 had significantly more POC than the surrounding soil (230% increase in NA and 100% NT + r30). Earthworm casts had higher values of MWD and WSA than physical soil aggregates in both NA and NT + r30 management treatments. Our results show the existence of a positive feedback loop we called earthworm-driven virtuous cycle. The increase in earthworm abundance promotes higher production of earthworm aggregates which are richer in organic matter and more water stable than the surrounding soil. This has favourable results in terms of soil quality but also increase crop yields (57% in maize and 18% in soybean), by means of biologically mediated soil processes, which is a highly desirable way to sustainability of agricultural production. Farmers, politicians and the whole society should pay more attention to soil as a key component supporting agricultural production by means of internal biological soil functioning.

Glyphosate may have negative or neutral effects on soil biota, but no information is available on the toxicity of AMPA to soil invertebrates. Therefore our aim was to study the effect of AMPA on mortality and reproduction of the earthworm species Eisenia andrei using standard soil ecotoxicological methods (ISO). Field-relevant concentrations of AMPA had no significant effects on mortality in acute or chronic assays. Except at the highest concentration tested, a significant biomass loss was observed compared to controls in the chronic assay. The number of juveniles and cocoons increased with higher concentrations of AMPA applied, but their mean weights decreased. This mass loss indicates higher sensitivity of juveniles than adults to AMPA. Our results suggest that earthworms coming from parents grown in contaminated soils may have reduced growth, limiting their beneficial roles in key soil ecosystem functions. Nevertheless, further research is needed to better understand the mechanisms underlying the sublethal effects observed here. Glyphosate was first introduced in crop production in 1971 1. However, its use expanded worldwide during the 1990's, when herbicide-resistant, genetically-engineered crops allowed widespread use by farmers of broad-spectrum herbicides such as glyphosate 2. Genetically modified (GM) crops now cover 175 million hectares in 27 countries worldwide, but 77% of that area is located in only three countries: USA (40%), Brazil (23%) and Argentina (14%) 3. The increased use of GM crops has been accompanied by a concomitant increase in glyphosate use. In Argentina, 238 million litres of glyphosate were sprayed in 2011, and in Brazil, approximately 340 million litres, raising concerns of the possible non-target effects of this herbicide, especially its potential impact on soil and water contamination and ecosystem functioning 4,5. Earthworms are one of the most important components of the soil biota in terms of soil formation and maintenance of soil structure and fertility 6. Furthermore, they are frequently used as indicators of soil quality and contamination levels, with standard, internationally recognized and adopted ecotoxicology assays 7-9. These methods include acute and chronic tests. The former evaluates short-term and lethal effects of a potentially toxic agent, providing information on possible quick and dramatic changes in earthworm communities. On the other hand, chronic tests evaluate sub-lethal responses in longer-term parameters that are often more sensitive to soil pollution, such as growth and reproduction. Although glyphosate effects on earthworms have been extensively studied, results are far from conclusive. Several studies consistently found very low mortality of Eisenia andrei Bouché, 1972 and Aporrectodea spp. worms at recommended (from 1,440 g ai.ha −1 to 1,800 g ai.ha −1) and higher doses of glyphosate 10-16. García-Torres et al. 17 reported significant mortality only at very high concentrations (50,000 mg.kg −1), but Piola et al. 18 found that lethal doses depended on the commercial formulations used. Conversely, sub-lethal parameters such as reproduction have usually been more sensitive than mortality in assessing glyphosate effects. For example, the number of juveniles and/or cocoons decreased at doses of 1 to 1,000 mg.kg

However, we are not paying enough attention to soil degradation produced by land use. Modern agriculture has been successful in increasing yields but has also caused extensive environmental damage, particularly soil degradation. In the Argentine Pampas, agriculturization reached a peak with the generalized use of the no-till technological package: genetically modified soybeans tolerant to glyphosate, no-till, glyphosate, and inorganic fertilizers. This phenomenon has been widely spread in the country; the no-till package has been applied in large areas and has been used by tenants in a 60%-70% of cultivated lands. Thus, those who were involved in developing management practices may not be the same as those who will face degradation issues related to those practices. Indeed, most evidence reviewed in this paper suggests that the most widely distributed practices in the Pampas region are actually producing severe soil degradation. Biological degradation is particularly important because soil biota is involved in numerous soil processes on which soil functioning relies, affecting soil fertility and productivity. For example, soil meso-and macrofauna are especially important in nutrient cycling and in soil structure formation and maintenance, and they are key components of the network that links microbial process to the scale of fields and landscapes where ecosystem services are produced. However, the knowledge of the impact of different agricultural managements on soil meso-and macrofauna in Pampas agroecosystems is far from conclusive at this stage. The reason for this lack of definite conclusions is that this area has been given less attention than in other parts of the world; the response of soil fauna to agricultural practices is complex and taxa-dependent; and there is a wide variety of practices in the main types of agricultural systems, making generalizations difficult. A review of the existing studies on soil meso-and macrofauna in agroecosystems, revealed that (a) agricultural soils, regardless of farming system, are strongly modified in biological aspects compared to the same soils without human interventions; (b) there are no conclusive results about no-till benefits compared to reduced tillage or conventional tillage; (c) agricultural managements that are alternative to the traditional conventional systems are very poorly represented in research.

However, there is still little evidence from field conditions about direct benefits of organic agriculture on soil ecosystem functioning. Hence, the aims of this study were to compare the effect of organic farming versus conventional farming on litter decomposition and to study how this process is affected by soil meso-and macrofauna abundances. Systems studied were: (1) organic farming with conventional tillage (ORG), (2) conventional farming with conventional tillage (CT), (3) conventional farming under no-tillage (NT), and (4) natural grassland as control system (GR). Decomposition was determined under field conditions by measuring weight loss in litterbags. Soil meso-and macrofauna contribution on decomposition was evaluated both by different mesh sizes and by assessing their abundances in the soil. Litter decomposition was always significantly higher after 9 and 12 months in ORG than in CT and NT (from 2 to 5 times in average), regardless decomposer community composition and litter type. Besides, mesofauna, macrofauna and earthworm abundances were significantly higher in ORG than in NT and CT (from 1.6 to 3.8, 1.7 to 2.3 and 16 to 25 times in average, respectively for each group). These results are especially relevant firstly because the positive effect of ORG in a key soil process has been proved under field conditions, being the first direct evidence that organic farming enhances the decomposition process. And secondly because the extensive organic system analyzed here did not include several practices which have been recognized as particularly positive for soil biota (e.g. manure use, low tillage intensity and high crop diversity). So, this research suggests that even when those practices are not applied, the non-use of agrochemicals is enough to produce positive changes in soil fauna and so in decomposition dynamics. Therefore, the adoption of organic system in an extensive way can also be suggested to farmers in order to improve ecosystem functioning and consequently to achieve better soil conditions for crop production.
Effect of Good Agricultural Practices under no-till on litter and soil invertebrates in areas with different soil types

When applied all together, GAPs promotes high productivity, while maintaining the production capacity of resources. In the Pampas region of Argentina, there is a need to assess the effects of these practices on soils, particularly on soil fauna, as they play an important role in soil functioning. The aim of this study was to evaluate the effect of the application of GAPs under NT on invertebrates and to assess whether this effect is different between soil types. We hypothesized (1) that GAP will produce an increase in the abundance, as well as changes in the faunal composition of litter and soil invertebrates; (2) that the effects will differ with soil type, and (3) that the changes in soil invertebrate fauna will be explained by soil properties. We compared two contrasting NT treatments -with and without GAP application-, replicated in three agricultural areas, on different soil types (Entic Haplustolls to Typic Argiudolls) situated across a west–east transect in the Pampas region of Argentina. A positive (Natural environment) and a negative (Conventional tillage) reference sites were included in the comparison. Litter and soil invertebrates and soil properties were assessed at each sampling site. Overall, our results indicated that the application of GAPs in productive NT fields increases litter and soil invertebrate abundance and modifies faunal composition. In the litter layer, four of the five taxa present were favoured by GAPs with an increase in the abundances of ants, prostigmatid mites, earthworms and collembolans. GAPs also induced changes in invertebrate faunal composition, from the initial NO-GAP situation to the present state under GAP system. The observed changes in litter and soil invertebrates, changes in faunal abundance and composition can be expected to translate to changes in soil functioning. Our last hypothesis was partially confirmed in that soil properties have to be considered in the examination of differences in fauna between treatments with there are only subtle differences in practices, as in the present study.
