Resumo: | Agriculture is the main economical activity in the state of Goiás, Brazil. The soils of the savannah (cerrado) became a source of attraction when the mechanization of agriculture, irrigation and the use of corrective chemicals were introduced. Since these technological advances have provided a more intense use, deeper studies on soil characteristics and proper management were required to reduce negative impacts. The degradation of the soil’s physical properties is one of the main processes which cause loss of structural quality and erosion by water. The soil’s texture, specific density, specific gravity of particles, porosity curve and moisture retention of four classes of agricultural soils of Goiás were examined to determine which classes of soil were more susceptible to erosion. Samples were collected from the central to the southwestern region of the state of Goiás, characterized as savannah. Descriptive statistics, with a confidence level of 95%, were employed. Correlation test for averages comparison was used to analyze texture and hydraulic retention curve. Dystrophic quartzose soil had a higher propensity towards erosion than other soil classes. In fact, it was the most vulnerable to erosion by water when the erosion factor (K) was taken into account. Usage techniques and soil management may reduce soil loss by erosion. |

Os solos de cerrado passaram a ser atrativos com a mecanização da agricultura, a irrigação artificial e a utilização de corretivos químicos. Esta evolução tecnológica propiciou um uso mais intenso e se torna necessário um estudo mais profundo das características dos solos para um manejo adequado, buscando reduzir impactos negativos. A degradação das propriedades físicas do solo é um dos principais processos responsáveis pela perda de qualidade estrutural e pelo aumento da erosão hídrica. Este trabalho teve por finalidade analisar a textura, a densidade específica do solo, a densidade específica de partículas, a porosidade e a curva de retenção de umidade de quatro classes de solos agricultáveis do Estado de Goiás, possibilitando determinar quais classes de solos são mais susceptíveis à erodibilidade. As coletas foram realizadas da porção central à porção sudoeste do território goiano, em uma área tipicamente de domínio de cerrado. Foram utilizados os cálculos de estatística descritiva, com nível de confiança de 95%. Para as análises de textura e de curva de retenção hidráulica foi utilizado o teste de correlação para comparação entre as médias. O neossolo quartzarênico (RQ) apresentou maior propensão a erodibilidade que as demais classes de solos avaliadas, sendo, portanto, mais vulnerável à erosão hídrica avaliando-se apenas pelo fator de erodibilidade (K). Técnicas de uso e manejo do solo podem reduzir a perda de solos por erosão hídrica.Unicesumar2020-07-22T18:11:46Z2020-07-22T18:11:46Z2011info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCASTRO, W.
