Resumo: | This work aimed to describe the frequency distribution of soil organic carbon contents under different conditions of Araucaria forest (concentration of araucaria trees, imbuia trees and mixed forest, with record of fire) in Paraná State, Brazil. Fitness quality of probability density functions (normal, Weber, Weibull 3P, log-normal, SB of Johnson and Gamma) were determined, using Kolmogorov Smirnov test. All functions fitted adequate, so they can all be used for any tested condition. Functions were ranked using Kolmogorov-Smirnov test. Gamma function was selected as the most appropriate for all tested conditions. However, after a comparison of fitted distributions by Kolmogorov-Smirnov test, we concluded that modeling must be performed separately. |

Para tal, foi avaliada a qualidade de ajuste e aderência de diferentes funções de probabilidade (normal, Weber, Weibull 3P, log-normal, SB de Johnson e Gama), pelo teste de Kolmogorov-Smirnov. Todas as funções densidade de probabilidade resultaram em bons ajustes, podendo então ser utilizadas para modelar os dados de carbono no solo em qualquer uma das parcelas. As funções foram ranqueadas a partir dos valores do teste Kolmogorov-Smirnov, e decidiu-se que a função Gama é a mais apropriada para modelar o teor de carbono nas três parcelas estudadas. Ainda, ao realizar a comparação das distribuições Gama ajustadas pelo teste Kolmogorov-Smirnov nas diferentes condições testadas, observou-se que elas apresentam configurações distintas, portanto, devem ser modeladas individualmente.Embrapa Florestas2017-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/95310.4336/2017.pfb.37.89.953Pesquisa Florestal Brasileira; v. 37 n. 89 (2017): jan./mar.; 29-37Pesquisa Florestal Brasileira; Vol. 37 No. 89 (2017): jan./mar.; 29-371983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/953/554Copyright (c) 2017 Tauane Garcia Barreto, Ângela Maria Klein Hentz, Sylvio Péllico Netto, Ana Paula Dalla Corte, Carlos Roberto Sanquettahttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessBarreto, Tauane GarciaKlein Hentz, Ângela MariaNetto, Sylvio PéllicoCorte, Ana Paula DallaSanquetta, Carlos Roberto2018-01-07T18:59:59Zoai:pfb.cnpf.embrapa.br/pfb:article/953Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-01-07T18:59:59Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
