Resumo: | The evaluation of the soil quality is important to identify potential problems of soil degradation.The assessment of the soil quality requires the determination of several soil parameters and the integration of specific soil properties measurements into mathematical models, such as the soil quality index (SQI).The aims of this study were to: (i) determine the SQI for an Ultisol under a remnant of Atlantic Rain Forest; (ii) use the SQI for the Atlantic Rain Forest as a reference to evaluate the effects of conventional and integrated management in coconut orchards. It was hypothesized that the conventional management of coconut (Cocos nuciferaL.) orchards reduces the SQI compared with Atlantic Rain Forest. A soil quality index was constructed using an additive model that considered three main soil functions (the ability of the soil to promote root growth, water storage and flux, and nutrient supply) and a set of soil indicators. The SQI values were 0.66, 0.54 and 0.46 for the Atlantic Forest,integrated and conventional orchards, respectively; therefore, there was decline in soil quality in both orchards. Even though there was an increase in the organic matter content in the integrated coconut orchard as result of the maintenance of the organic residues on the soil surface and the presence of cover crops, the SQI indicated that, in that type of highly weathered soil, a more conservative approach needs to be applied to avoid further soil quality degradation. |

A avaliação da qualidade do solo é importante para identificar potenciais problemas de degradação do solo. Para tanto, é necessário a determinação de vários parâmetros bem como a integração de propriedades específicas do solo em modelos matemáticos, como por exemplo, o índice de qualidade do solo (IQS). Os objetivos do presente estudo foram: i) determinar o IQS de um Argissolo sob Mata Atlântica; ii) utilizar o IQS da Mata Atlântica para avaliar os efeitos dos manejos convencional e integrado em pomares de coco (Cocos nucífera L). A hipótese postulada foi a de que o manejo convencional do coqueiro reduz o IQS quando comparado com a Mata Atlântica. O IQS foi construído usando um modelo aditivo que considerou três principais funções do solo (capacidade do solo em promover crescimento do sistema radicular, permitir o fluxo e o armazenamento de água, e fornecer nutrientes) e um grupo de indicadores. Os valores do IQS foram 0,66; 0,54; 0,46, para a Mata Atlântica, manejo integrado e manejo convencional, respectivamente. Portanto, houve um declínio na qualidade do solo nos dois pomares. Embora tenha sido observado um aumento no teor de material orgânico no pomar de manejo integrado, onde os resíduos orgânicos e culturas de cobertura são dispostos na superfície do solo, o IQS indicou que, em solos muito intemperizados, as práticas conservacionistas precisam ser mais efetivas.UEL2016-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2317110.5433/1679-0359.2016v37n6p3847Semina: Ciências Agrárias; Vol. 37 No. 6 (2016); 3847-3858Semina: Ciências Agrárias; v. 37 n. 6 (2016); 3847-38581679-03591676-546Xreponame:Semina.
