Resumo: | Soils are fundamental for human development and an infinite number of animal and plant species, however, research has shown that their production capacity is threatened because of their impoverishment. For this reason, the study aimed to spatialize the soil nutrients in the Pirajibu-Mirim river watershed, as well as to estimate the loss of these nutrients by water erosion by sub-basin to identify which have a greater contribution of soil particles to the watercourses. The soil was collected in 30 sampling points evenly distributed in the Pirajibu-Mirim watershed at a depth of 0-20 cm and geospatialized in a Geographic Information System (GIS). The Universal Soil Loss Equation (EUPS) was used to estimate soil loss and, afterward, nutrient losses by hydrographic sub-basins were computed. Results showed more significant losses in the Light and Moderate classes, with an average soil loss of 5.92 t/ha.year. The lost soil nutrients showed high values, mainly for calcium (28,525.29 kg/year), iron (15,130.62 kg/year) and organic matter (674,088.91 kg/year). Soil particles can contribute to watercourses and reservoirs compromising the quality and quantity of water through the dam eutrophication and silting, culminating in health and environmental problems. |

O estudo objetivou espacializar nutrientes do solo da bacia hidrográfica do rio Pirajibu-Mirim e estimar a perda desses nutrientes por erosão hídrica por sub-bacia hidrográfica para identificar quais contribuem com maior aporte de partículas de solo nos cursos de água. A coleta de solo foi realizada em 30 pontos distribuídos uniformemente na bacia hidrográfica do Pirajibu-Mirim na profundidade de 0-20 cm e geoespacializados em Sistema de Informação Geográfica (SIG). Foi utilizada a Equação Universal de Perda de Solos (EUPS) para estimar a perda de solo e, após, foram computadas as perdas de nutrientes por sub-bacia hidrográfica. Os resultados evidenciaram perdas mais expressivas nas classes Leve e Moderada, com uma perda de solo média de 5,92 t/ha.ano. Os nutrientes do solo perdidos apresentaram valores elevados, principalmente para cálcio (28.525,29 kg/ano), ferro (15.130,62 kg/ano) e matéria orgânica (674.088,91 kg/ano). As partículas de solo podem aportar cursos de água e reservatório, comprometendo a qualidade e quantidade de água por meio da eutrofização da represa e assoreamento, culminando em problemas de ordem sanitária e ambiental.EDUFU - Editora da Universidade Federal de Uberlândia2022-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/5889510.14393/RCG238758895Caminhos de Geografia; Vol. 23 No. 87 (2022): Junho; 84-102Caminhos de Geografia; Vol. 23 Núm. 87 (2022): Junho; 84-102Caminhos de Geografia; v. 23 n. 87 (2022): Junho; 84-1021678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/58895/33957Copyright (c) 2022 Vanessa Cezar Simonetti, Darllan Collins da Cunha Silva, André Henrique Rosahttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSimonetti, Vanessa CezarSilva, Darllan Collins da CunhaRosa, André Henrique2022-07-25T12:30:51Zoai:ojs.www.seer.ufu.br:article/58895Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2022-07-25T12:30:51Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
