Resumo: | The bulk density values indicative of compaction in clayey soils correspond to a wide range of values (1.30-1.47 Mg m-3), due to the diverse types of soil management. Our hypothesis is that if we consider bulk density values within similar management groups (those that fall to the ground and those that do not fall), the values will be more accurate within each management group. Our objective in this work was to analyze using the concepts of (Yates & Cochran, 1938; Whitehead, 2002) what is a suitable statistical way of grouping these results to reach a consensus regarding a tested hypothesis, the greatest number of density values surveyed between 1977 and 2021, considered for the study of compaction in clayey Oxisols under different managements, to verify whether our hypothesis will be confirmed. We selected 1,521 studies with bulk densities in the literature, corresponding to 44 years (1977 and 2021), which were analyzed by a statistical technique that integrates the results of two or more independent studies on the same subject and combines them into a summary measure (portion forestry). From the data collected in the literature, it was possible to separate two groups of bulk density and management in clayey soils indicative of compaction: the managements that perform little or no manipulation of the soil, such as pasture and no-tillage, densities between 1.41-1.45 Mg.m-3 (average 1.43 Mg m-3), and for the others, such as conventional plowing and minimum tillage, soil densities between 1.31-1.38 Mg.m-3 (average 1.35 Mg m-3). Finally, we conclude that compaction must be analyzed considering the texture and type of soil management. |

Nossa hipótese é que se considerarmos os valores de densidade do solo dentro de grupos de manejo semelhantes (os que caem no chão e os que não caem), os valores serão mais precisos dentro de cada grupo de manejo. Nosso objetivo neste trabalho foi analisar usando os conceitos de (Yates & Cochran, 1938; Whitehead, 2002) qual é uma forma estatística adequada de agrupar esses resultados para chegar a um consenso sobre uma hipótese testada, o maior número dos valores de densidade levantados entre 1977 e 2021, considerados para o estudo da compactação em Latossolos argilosos sob diferentes manejos, para verificar se nossa hipótese será confirmada. Selecionamos 1.521 estudos com densidades do solo na literatura, correspondentes a 44 anos (1977 e 2021), que foram analisados por uma técnica estatística que integra os resultados de dois ou mais estudos independentes sobre o mesmo assunto e os combina em uma medida resumida (forest plot). A partir dos dados levantados na literatura, foi possível separar dois grupos de densidade do solo e manejo em solos argilosos indicativos de compactação: os manejos que realizam pouca ou nenhuma manipulação do solo, como pastagem e plantio direto, densidades entre 1,41 -1,45 Mg.m-3 (média 1,43 Mg m-3), e para as demais, como aração convencional e preparo mínimo, densidades de solo entre 1,31-1,38 Mg.m-3 (média 1,35 Mg m-3). Por fim, concluímos que a compactação deve ser analisada considerando a textura e o tipo de manejo do solo.UEL2023-06-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4763710.5433/1679-0359.2023v44n2p895Semina: Ciências Agrárias; Vol. 44 No. 2 (2023); 895-910Semina: Ciências Agrárias; v. 44 n. 2 (2023); 895-9101679-03591676-546Xreponame:Semina.

The bulk density values indicative of compaction in clayey soils correspond to a wide range of values (1.30-1.47 Mg m-3), due to the diverse types of soil management. Our hypothesis is that if we consider bulk density values within similar management groups (those that fall to the ground and those that do not fall), the values will be more accurate within each management group.

Finally, we conclude that compaction must be analyzed considering the texture and type of soil management. |
