“…However, there have been some reports of harmful effects on microorganisms, insects and frogs, which has prompted increased interest in investigating its potential adverse effects on field populations of earthworms (e.g. García‐Pérez, Alarcón, Hernández, & Hernández, ; García‐Pérez, Alarcón‐Gutiérrez, Perroni, & Barois, ; García‐Torres, Giuffré, Romaniuk, Ríos, & Pagano, ; Gaupp‐Berghausen, Hofer, Rewald, & Zaller, ; Givaudan, Binet, Le Bot, & Wiegand, ) and to date, the results vary from negative to no effect.…”

AbstractThe adoption of less intensive soil cultivation practices is expected to increase earthworm populations and their contributions to ecosystem functioning. However, conflicting results have been reported on the effects of tillage intensity on earthworm populations, attributed in narrative reviews to site-dependent differences in soil properties, climatic conditions, and agronomic operations (e.g., fertilization, residue management and chemical crop protection).We present a quantitative review based on a global meta-analysis, using paired observations from 215 studies performed over 65 years across 40 countries on five continents, to elucidate this long-standing unresolved issue. Results showed that disturbing the soil less (e.g., no-tillage and Conservation Agriculture) significantly increased earthworm abundance (mean increase of 137% and 127%, respectively) and biomass (196% and 101%, respectively) compared to when the soil is inverted by conventional ploughing. Earthworm population responses were more pronounced when the soil had been under reduced tillage for a long time (>10 years), in warm temperate zones with fine-textured soils, and in soils with higher clay contents (>35%) and low pH (<5.5). Furthermore, retaining organic harvest residues amplified this positive response to reduced tillage, whereas the use of the herbicide glyphosate did not significantly affect earthworm population responses to reduced tillage.Additional meta-analyses confirmed that epigeic and, more importantly, the bigger-sized anecic earthworms, were the most sensitive ecological groups to conventional tillage. In particular, the deep burrower Lumbricus terrestris exhibited the strongest positive response to reduced tillage, increasing in abundance by 124% more than the overall mean of all 13 species analysed individually. The restoration of these two important ecological groups of earthworms and their burrowing, feeding and casting activities under various forms of reduced tillage will ensure the provision of ecosystem functions such as soil structure maintenance and nutrient cycling by "nature's plough".

“…Finally, Piola et al [61] found that lethal rates depended on commercial herbicide formulations. Regarding reproduction parameters, the number of juveniles and/or cocoons decreased at rates of 1 to 1000 mg¨kg´1 [55], 5000 mg¨kg´1 [60] and 1440 mg¨ai¨ha´1 [54]. However, other studies found no significant effects of glyphosate on measured earthworm reproduction parameters [53,56,57,62].…”

Large-Scale Agricultural Management and Soil Meso- and Macrofauna Conservation in the Argentine Pampas

Soil is the most basic resource for sustainable agricultural production; it promotes water quality, is a key component of the biogeochemical cycles and hosts a huge diversity of organisms. 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.

“…The soil properties impeded a consistent assessment of toxicity for D. annae . Octolasion tyrtaeum , an earthworm from Argentinean agroecosystems, has also been tested with glyphosate and was found to be more sensitive than E. fetida . The earthworm tests with A. gracilis and D. annae were performed with organisms collected from the field because they could not be cultured in the laboratory.…”

Soils from some Latin American countries support the highest biodiversity levels on the planet and simultaneously have some of the most serious environmental impacts attributed to both historical and current agricultural practices and industrial activities. Soil contamination has resulted from intensive use of pesticides, extensive mining and other industrial activities, and uncontrolled management of waste within inappropriate regulatory frameworks. The present study presents an overview of the scientific research on soil ecotoxicology conducted in Latin America, summarizing the recent advances and highlighting the needs for further refinements in this research field. Most of the contributions to the scientific literature have been from Brazil. The most investigated issue is the ecotoxicity of pesticides and earthworms, which were the organisms most frequently used as test species. Needs identified by Latin American researchers include methods and procedures for: 1) identifying and collecting natural soils to be used as reference test-substrates in tests, 2) identifying and discerning the range of sensitivities of native test species to soil contaminants, 3) developing environmental guidelines applicable to tropical/subtropical conditions, and 4) developing methods and procedures for higher tier testing for full development and implementation of environmental risk assessment schemes. The protection of Latin American soils, including provision of goods and services, is currently framed in legislation and other regulations, but implementation requires significant improvement and additional training programs.
