Resumo: The objective of this work was to study the spatial behavior of erodibility of a humic Red Yellow Oxisol through distribution maps and uncertainty using kriging methods. The experiment was set in an area cultivated to Coffea arabica L. cv catuai. The soil was collected from 0 to 0.20 m depth, from 50 points distributed in a sampling grid. Initially, the soil erodibility was evaluated with the use of indirect models based on soil particle fractions and organic matter content. Data were initially subjected to a descriptive and exploratory analysis. Geoestatistic analysis was used on the set of real data and also on the erodibility data after codification by indication. Results were interpolated by ordinary and indicative kriging to make maps of distribution and uncertainties. The mean erodibility value was higher than tolerated for Oxisol soils, and in the major portion of the area, probability of finding erodibility values greater than 50%, was high at the higher land elevations.

O experimento foi realizado em uma área cultivada com Coffea arabica L. variedade catuaí. O solo foi coletado na camada de 0-0,20 m distribuídos em uma malha amostral, totalizando 50 pontos. Avaliou-se a erodibilidade por meio de modelos indiretos, com base nas frações granulométricas do solo e no teor de matéria orgânica. Os dados foram, inicialmente, submetidos a uma análise descritiva e exploratória. A análise geoestatística foi utilizada sobre o conjunto real de dados e também sobre os dados de erodibilidade após codificação por indicação. Os resultados foram interpolados por krigagem ordinária e krigagem indicativa para a confecção de mapas de distribuição e incertezas. O valor médio de erodibilidade encontra-se acima do tolerado para Latossolos, sendo que na maior proporção da área a probabilidade de encontrar valores de erodibilidade acima do tolerado para Latossolos e maior que 50%, principalmente nas porções mais altas do terreno.Universidade Federal de Viçosa - UFV2009-08-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/2010.13083/reveng.v17i4.24Engineering in Agriculture; Vol. 17 No. 4 (2009); 274-282Revista Engenharia na Agricultura - REVENG; v. 17 n. 4 (2009); 274-2822175-68131414-398410.13083/reveng.v17i4reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/20/17Silva, Samuel de AssisLima, Julião Soares de SouzaTeixeira, Mauri Martinsinfo:eu-repo/semantics/openAccess2023-01-19T12:48:53Zoai:ojs.periodicos.ufv.br:article/20Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:48:53Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
