Resumo: The temporal variation in the attributes used to evaluate soil fertility is an indispensable tool to correct eventual deficiencies and excesses in the management of fertilization and liming in the fields. The present study was carried out using results from 92,566 soil analyzes from samples sent by farmers to official laboratories in the Western Santa Catarina from 1980 to 2016, with a periodicity of four years. The distribution classes of each attribute were the same as those used in a previous study, published in 1994, grouping those classes with very small percentage of samples. In general, we observed an increase in the percentage of samples in the classes with higher clay content, available phosphorus and exchangeable potassium, stability in the percentage of the classes of pH in water and exchangeable Calcium + Magnesium content and reduction in the classes with higher content of organic matter

O presente estudo foi realizado utilizando resultados de 92.566 análises do solo, realizadas em amostras enviadas por agricultores para os laboratórios oficiais localizados na Região Oeste Catarinense no período de 1980 a 2016, com uma periodicidade de quatro anos. As classes de distribuição de cada atributo foram as mesmas utilizadas em estudo anterior, publicado em 1994, agrupando-se aquelas que apresentavam percentual muito pequeno de amostras. De uma forma geral, observou-se aumento no percentual de amostras nas classes de maior teor de argila, fósforo disponível e potássio traçável, estabilidade no percentual das classes de pH em água e teor de cálcio + magnésio trocáveis e redução nas classes de maior teor de matéria orgânica.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2019-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/44610.22491/RAC.2019.v32n3.11Agropecuária Catarinense Journal; Vol. 32 No. 3 (2019); 78-83Agropecuária Catarinense; v. 32 n. 3 (2019); 78-832525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/446/454Copyright (c) 2019 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessda Veiga, MiltonSpagnollo, EvandroMantovani, Analu2020-04-28T21:40:08Zoai:ojs.publicacoes.epagri.sc.gov.br:article/446Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2020-04-28T21:40:08Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
