Resumo: | The inadequate use and management in cropping systems in the semiarid region may decline the soil's ability to sustain the production. The objective of this work was to determine the soil quality index (SQI) in agroecological and conventional irrigated agricultural experimental units (AEU), located in the community of Sombras Grandes, Caraúbas, Rio Grande do Norte. Simple soil samples (0-20cm) were collected from 2009 to 2012. To determine the SQI, it was used 11 quality indicators associated to the soil functions in maintain the productivity capacity over time: bulk density (Bd), total porosity (TP), penetration resistance (PR), water availability in soil (AWS/TP), moisture retention at -33 kPa (MR/TP), pH, phosphorus assimilable (P), cation exchange capacity (CEC), base saturation (V), soil organic matter (SOM), clay dispersed in water (CDW) and flocculation degree (FD). The SQI in agroecological and conventional irrigated AEU were classified as good (0.80) and bad (0.45), respectively. In conventional AEU there is need for agricultural practices, like injection of organic waste, that improve the FD because it was the indicator that most contributed to reduce the SQI. The SQI reflected the integrated performance of the chemical and physical properties, which can be used in making decisions about the soil use and management. |

O objetivo do estudo foi determinar o índice de qualidade do solo (IQS) em unidades experimentais agrícolas (UEA) irrigadas agroecológica e convencional, localizadas na comunidade de Sombras Grandes, Caraúbas, Rio Grande do Norte. As amostras simples de solo (0-20cm) foram coletadas no período de 2009 a 2012. Para determinar o IQS, utilizaram-se 11 indicadores de qualidade associados às funções do solo em manter a capacidade produtiva ao longo do tempo: densidade do solo (Ds), porosidade total (PT), resistência à penetração (RP), disponibilidade de água no solo (AD/PT), retenção de umidade a -33 kPa (UVcc/PT), pH, fósforo assimilável (P), capacidade de troca catiônica (CTC), saturação de bases (V), matéria orgânica do solo (MOS), argila dispersa em água (ADA) e grau de floculação (GF). O IQS nas UEAs agroecológica e convencional foram classificados como ótimo (0,80) e ruim (0,45), respectivamente. Na UEA convencional há necessidade de práticas agrícolas como aporte de resíduos orgânicos que melhorem o GF, pois foi o indicador que mais contribuiu para reduzir o IQS. O IQS reflete a integração dos atributos químicos e físicos, podendo ser utilizado nas tomadas de decisão sobre o uso e manejo do solo.Editora Verde2018-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfapplication/pdfapplication/pdfapplication/pdfapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/533310.18378/rvads.v13i1.5333Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 No. 1 (2018); 97 - 105Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 Núm. 1 (2018); 97 - 105Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 13 n. 1 (2018); 97 - 1051981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/5333/4919https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5333/4929https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5333/9378https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5333/9379https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5333/9381https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5333/9382Copyright (c) 2018 Fábio dos Santos Santiago et al.info:eu-repo/semantics/openAccessSantiago, Fábio dos SantosMontenegro, Suzana Maria Gico LimaPinheiro, Maria Rafaela de Almeida2021-06-14T13:14:24Zoai:ojs.gvaa.com.br:article/5333Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:22.968949Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
