Resumo: This study aimed to determine and spatialize the soil quality index (SQI), in relation to chemical and physical attributes, and evaluate its use in the payment for environmental services in the Sub-Basin of Posses, Extrema-MG, Brazil, which represents the Atlantic Forest Biome. SQI values were influenced by both the replacement of native forests by stands of eucalyptus and by pastures and annual crops, reflecting in the reduction of soil quality in the sampled layer in the evaluated systems. The spatialization of SQI showed values ranging from 0.40 to 0.80, with some specific areas with high values and others with values above 1.00 (native forest). The reforestation with eucalyptus conditioned most of the soils with low chemical and physical deterioration, due to accumulation of litter. The lowest SQI values are associated with pastures. SQI adjusted to the exponential model, which allowed the use of ordinary Kriging. The SQI has a great potential of use in the payment to farmers who provide services of soil and water conservation.

Os valores do IQS foram influenciados tanto pela substituição da mata nativa por povoamento de eucalipto, quanto por pastagens e culturas anuais, refletindo na redução da qualidade do solo na profundidade amostrada nos sistemas avaliados. A espacialização do IQS apresentou valores variando de 0,40 a 0,80, ocorrendo algumas áreas pontuais com elevados índices e algumas com índices superiores a 1,00 (mata nativa). O reflorestamento com eucalipto condicionou solos, em sua maioria, com baixas deteriorações físicas e químicas devido ao acúmulo de serrapilheira. Já os menores valores do IQS estão associados às pastagens. O modelo pelo qual o IQS se ajustou foi o exponencial, possibilitando a krigagem ordinária. O IQS apresenta grande potencial para uso no pagamento de agricultores que prestam serviços de conservação do solo e água.Departamento de Engenharia Agrícola - UFCG2019-02-15T09:30:22Z2019-02-15T09:30:22Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfLIMA, G.
