| description | The soil has become an essential resource for the survival of human beings, but with the increasing levels of contamination generated by human actions, this resource is getting all this pollution load resulting in changes in their properties. Based on that, this study aimed to characterize the physical and chemical properties of soil under different uses in the Watershed of the Vacacaí-Mirim river. The clay content ranged from 8 to 51% with a mean of 28,84 ± 12,18%, the concentration of potassium ranged from 0,8 to 208 mg kg-1, with a mean of 54,56 ± 47,16 mg kg-1. The values of organic matter ranged from 0,6 to 2,9%, with a mean of 1,50 ± 0,63%, the concentration of phosphorus ranged from 0,7 to 6 mg kg-1 with a mean of 2,36 ± 1,52 mg kg-1, the pH values ranged from 4,2 to 5,8 with a mean of 4,76 ± 0,39. Among the analyzed parameters, we highlight the high levels of clay and organic matter in soils that are where the use is native forest and native field, being possible to say that the preservation of the soil contributes to the maintenance of these parameters. Among the chemical attributes, the highest concentrations are related to soils that have undergone human action, such as the ones grown with rice and soybean and the places used as pasture. |

O solo se tornou um recurso essencial à sobrevivência do ser humano, porém com o aumento dos níveis de contaminação gerado pelas ações antrópicas, esse recurso está recebendo toda essa carga poluidora acarretando em mudanças em suas propriedades. Com base nisso, o presente trabalho teve por objetivo caracterizar os atributos físicos e químicos de solo sob diferentes usos em uma bacia hidrográfica. Os teores de argila variaram de 8 a 51%, com média de 28,84 ± 12,18%, a concentração de Potássio variou de 0,8 a 208 mg kg-1, com média de 54,56 ± 47,16 mg kg-1. Os valores de Matéria Orgânica variaram de 0,6 a 2,9%, com média de 1,50 ± 0,63%, a concentração de Fósforo variou de 0,7 a 6 mg kg-1 com média de 2,36 ± 1,52 mg kg-1, já os valores de pH variaram de 4,2 a 5,8com média de 4,76 ± 0,39. Dentre os parâmetros analisados, destaca-se em os valores elevados de argila e M.O. os solos que estão sob uso de mata nativa e campo nativo, sendo possível afirmar que a preservação do solo contribui para manutenção destes parâmetros. Dentre os atributos químicos, os maiores valores relacionam-se com solos sob que sofreram ação antrópica, como cultivados com arroz e soja ou sob uso de pastagem. 2012-12-13 2022-03-17T15:13:55Z 2022-03-17T15:13:55Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.revistas.usp.br/rdg/article/view/52756 10.7154/RDG.2012.0024.0006 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/41949 por https://www.revistas.usp.br/rdg/article/view/52756/56611 Copyright (c) 2012 Pedro Daniel da Cunha Kemerich, Sérgio Roberto Martins, Masato Kobiyama, Galileo Adeli Buriol, Alencar Simão Rizzardi, Régis Leandro Lopez da Silva, Willian Fernando de Borba application/pdf Universidade de São Paulo.
