Resumo: | The objective of this work was to construct a simple index based on the presence/absence of different groups of soil macrofauna to determine the ecological quality of soils. The index was tested with data from 20 sites in South and Central Tabasco, Mexico, and a positive relation between the model and the field observations was detected. The index showed that diverse agroforestry systems had the highest soil quality index (1.00), and monocrops without trees, such as pineapple, showed the lowest soil quality index (0.08). Further research is required to improve this model for natural systems that have very low earthworm biomass ( < 10 g m-2) and a high number of earthworm species (5–7), as it is in the tropical rain forest, whose soil quality index was medium (0.5). The application of this index will require an illustrated guide for its users. Further studies are required in order to test the use of this index by farmers. |

O índice foi testado com dados de 20 locais do sul e centro do Estado de Tabasco, México, e foi observada uma correlação positiva entre o dados gerados pelo modelo e pelas observações de campo. O índice de qualidade de solo mostrou que diversos sistemas agroflorestais tiveram a mais alta qualidade de solo (1,0) e que os monocultivos sem árvores, como o de abacaxi, apresentaram a qualidade de solo mais baixa (0,08). Este modelo precisa ser melhor desenvolvido para ser aplicado eficientemente em sistemas que apresentam naturalmente baixas densidades de minhocas ( < 10 g m-2) e número elevado de espécies de minhocas (5–7), como ocorre em solos de floresta tropical, cujo índice de qualidade de solo apresentou valores médios (0,5). A aplicação desse índice precisará de um guia ilustrado para os seus usuários. Mais estudos são necessários para testar o seu emprego por fazendeiros.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraHuerta, EsperanzaKampichler, ChristianGeissen, VioletteOchoa-Gaona, SusanaJong, Ben deHernández-Daumás, Salvador2010-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1383Pesquisa Agropecuaria Brasileira; v.44, n.8, ago. 2009: Thematic Issue XV International Colloquium on Soil Zoology and XX Colloquium on Apterygota; 1056-1062Pesquisa Agropecuária Brasileira; v.44, n.8, ago. 2009: Thematic Issue XV International Colloquium on Soil Zoology and XX Colloquium on Apterygota; 1056-10621678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1383/5803info:eu-repo/semantics/openAccess2012-06-17T11:52:08Zoai:ojs.seer.sct.embrapa.br:article/1383Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:52:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
