“…Some studies note that different landuse and management systems negatively affect these organisms; these systems include areas of agroforestry (LIMA et al, 2010), areas of pasture with epigean fauna in the litter (NUNES et al, 2012;LUZ et al, 2013), sugarcane (ABREU et al, 2014), and grain-production systems in the Cerrado (SANTOS et al, 2016).…”

The aim of this study was to characterize the soil macrofauna under different crop systems and compare them to the macrofauna under the native vegetation of a Cerrado/Caatinga ecotone in southwestern Piauí State, Brazil. The areas studied included areas under sweetsop cultivation (Annona squamosa L.), andropogon grass with three years of use, andropogon grass with six years of use, pivot-irrigated corn, Napier grass, and native vegetation. In each area, soil layers of 0-0.1, 0.1-0.2, and 0.2-0.3m, including the surface litter, were evaluated following the Tropical Soil Biology and Fertility Program (TSBF) recommendations. The soil macrofauna from the different land-use systems were identified to the family level, and the mean density of each taxon was calculated for each soil-management type and layer. The structure of the soil macrofauna was negatively altered under the different crops in comparison to the native Cerrado/Caatinga vegetation, with macrofaunal occurrence varying in the different soil layers. A correlation existed between the functional groups and the soil grain-size distribution and moisture. Napier grass cultivation favored greater soil macrofaunal abundance, with a predominance of families belonging to the orders Isoptera and Hymenoptera. Number of soil macrofaunal families under pivot-irrigated corn was more like the number observed with the native vegetation, and corn also had greater family diversity compared to the other crops studied. Therefore, pivot-irrigated corn can reduce the impact of anthropogenic land use on the diversity of soil macrofauna.

“…Similar results were reported by Abreu et al . (), who observed a greater density of individuals when more than 50% of straw (equivalent to 5.1 Mg ha −1 of dry basis) was maintained on the soil surface. The increased diversity of soil macrofauna may be attributed to high levels of nutrients in soil under sugarcane cultivation (Franco et al ., ).…”

Agronomic and environmental implications of sugarcane straw removal: a major review

Large‐scale bioenergy demand has triggered new approaches to straw management in Brazilian sugarcane fields. With the progressive shift from a burned to a nonburned harvest system, most of the straw presently retained on the soil surface has become economically viable feedstock for bioenergy production. The trade‐offs between the need to preserve soil quality and produce more bioenergy have been the subject of intense discussion. This study presents a synthesis of available information on the magnitude of the main impacts of straw removal from sugarcane fields for bioenergy production and therefore represents an easily available resource to guide management decisions on the recommended amount of straw to be maintained on the field to take advantage of the agronomic, environmental, and industrial benefits. Crop residues remaining on sugarcane fields provide numerous ecosystem services including nutrient recycling, soil biodiversity, water storage, carbon accumulation, control of soil erosion, and weed infestation. Furthermore, several studies reported higher sugarcane production under straw retention on the field, while few suggest that straw may jeopardize biomass production in cold regions and under some specific soil conditions. Pest control is among the parameters favored by straw removal, while N2O emissions are increased only if straw is associated with the application of N fertilizer and vinasse. An appropriate recommendation, which is clearly site specific, should be based on a minimum mass of straw on the field to provide those benefits. Overall, this review indicates that most of the agronomic and environmental benefits are achieved when at least 7 Mg ha−1 of dry straw is maintained on the soil surface. However, modeling efforts are of paramount importance to assess the magnitude and rates of straw removal considering the several indicators involved in this complex equation, so that an accurate straw recovery rate could be provided to producers and industry toward greater sustainability.

“…Among the biological indicators are several groups of organisms that interact, influence and are influenced by the physical, chemical and biological properties of the soil through mechanisms such as soil structuring and homogenization, plant material fragmentation, decomposition and nutrient cycling. Therefore, these soil communities, due to their strong interactions with soil, can be deeply affected by diverse management practices related to processes such as changes in soil use, monocultures, application of pesticides and fertilizers, compaction, availability of nutrients, and others (ABREU et al, 2014;SIQUEIRA et al, 2016).…”

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.Resumo: O filo Arthropoda é um dos grupos mais diversos da superfície terrestre, compreendendo diferentes classes de insetos que ocupam diversos ambientes. Alguns grupos, entretanto, apresentam relação estreita com o habitat que ocupam, respondendo de forma significativa às modificações no ambiente, o que acaba indicando o nível de alteração desse mesmo ambiente através de sua presença ou ausência. O presente estudo objetivou demonstrar a importância da fauna edáfica como bioindicadora de qualidade ambiental. Trata-se de uma revisão bibliográfica baseada em consulta especializada de artigos científicos nos bancos de dados Google Acadêmico, SciELO-Scientific Eletronic Library e ResearchGate. Os trabalhos encontrados apontaram que a qualidade ambiental pode ser mensurada a partir da diversidade e abundância de artrópodes que vivem e desempenham suas funções no solo. A macrofauna influencia importantes processos químicos e físicos do solo como a ciclagem de nutrientes, estruturação e homogeneização, aumento da produtividade, dentre outros. Já a mesofauna, além de atuar sobre as propriedades edáficas, atua na regulação de populações microbianas e é sensível às alterações, respondendo pr...
