Resumo: The objective of this work was to estimate the rill and interrill erodibility coefficient through soil color parameters. Three areas were selected, which were cultivated with soybean in cohesive Ultisols of the eastern region of the state of Maranhão, Brazil. In each area, 121 samples were collected at a depth of 0.00–0.20 m. The values of diffuse reflectance spectroscopy in the visible range were determined, in order to obtain the values of hue, value, and chroma. From these color constituents, the redness index was calculated for each sample. Models were developed to evaluate the effect of each color component on rill and interril erodibility. These components showed R2 ranging from 0.37 to 0.70. The generated models obtained R2 of 0.70 and 0.73 for interill and rill, respectively. Soil color determined by diffuse reflectance spectroscopy can be used as an alternative method to estimate the erodibility coefficient of cohesive Ultisols.

Foram selecionadas três áreas cultivadas com soja, em Argissolos Amarelos coesos do Leste Maranhense. Em cada área, foram retiradas 121 amostras na profundidade de 0,00–0,20 m. Foram determinados os valores de espectroscopia de reflectância difusa na faixa do visível, para obtenção dos valores de matiz, valor e croma. A partir destes constituintes da cor, foi calculado o índice de avermelhamento para cada amostra. Foram desenvolvidos modelos para avaliar o efeito de cada componente da cor sobre a erodibilidade em sulcos e entressulcos. Esses componentes apresentaram R2 que variou de 0,37 a 0,70. Os modelos gerados obtiveram R2 de 0,70 e 0,73, para entressulcos e sulcos, respectivamente. A cor do solo determinada por espectroscopia de reflectância difusa pode ser utilizada como método alternativo para estimar o coeficiente de erodibilidade de Argissolos Amarelos coesos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDantas, Jussara SilvaMartins Filho, Marcílio VieiraMarques Júnior, JoséResende, José Maria do AmaralTeixeira, Daniel De BortoliBarbosa, Ronny SobreiraSiqueira, Diego Silva2014-10-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/18773Pesquisa Agropecuaria Brasileira; v.49, n.9, set. 2014; 700-707Pesquisa Agropecuária Brasileira; v.49, n.9, set. 2014; 700-7071678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/18773/12788https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/18773/11156info:eu-repo/semantics/openAccess2014-10-20T19:27:26Zoai:ojs.seer.sct.embrapa.br:article/18773Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-20T19:27:26Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
