Resumo: | Data of infiltration of water in soil were obtained in several points of a rectangular grid of an agricultural parcel of Experimental Farm of EMEPA-PB, Brazil, with the objective of characterizing the spatial variability of the infiltration and the hydrodynamic parameters of the soil. Data were fitted both to the Green & Ampt and Philip equations for the adjustment of the values obtained. Granulometric, soil density and soil moisture measurements were performed just before and after the infiltration tests. Classical statistics and geostatistics were used to describe the spatial variability of infiltration parameters given by the fitting to the theoretical laws. Suction parameter of Green & Ampt equation was shown to be the more sensitive to the soil spatial variability of the parcel. No correlation between infiltration parameter and soil texture was found. |

Foram utilizadas as leis de Philip e de Green & Ampt para ajustamento dos valores obtidos. Medições de granulometria, densidade do solo e umidade volumétrica antes e depois dos testes de infiltração foram efetuadas. Técnicas de análises estatísticas clássicas e geoestatísticas foram utilizadas para descrever a variabilidade espacial dos parâmetros de infiltração, obtidos pelo ajustamento às leis teóricas. Dos parâmetros estudados, o de sucção da equação de Green & Ampt se mostrou o mais sensível à variabilidade espacial da parcela. Também não se notou correlação entre os parâmetros de infiltração e a textura.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLima, Cícero Aurélio GrangeiroSilans, Alain Passerat de1999-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5565Pesquisa Agropecuaria Brasileira; v.34, n.12, dez. 1999; 2311-2320Pesquisa Agropecuária Brasileira; v.34, n.12, dez. 1999; 2311-23201678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5565/2756info:eu-repo/semantics/openAccess2010-06-29T17:46:33Zoai:ojs.seer.sct.embrapa.br:article/5565Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-06-29T17:46:33Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
