总结: | The soil acidity has as its main factor the limitation in plant development in agricultural production in several sectors of the world. The general objective of this study was to evaluate the reapplication of soil acidity correctives, ground rock limestone (CRM), ground rock silicate (SRM) and calcined limestone (CC), associated or not with agricultural gypsum (GA) on soil aggregation in no-till farming system (SPD). The present study was conducted in the experimental area of the ABC Foundation Experimental Demonstration Field (EDC), in the city of Ponta Grossa-PR, LATOSSOLO VERMELHO-AMARELO Distrófico de textura argilo-arenosa. The treatments were the three soil acidity correctors CRM (4,8 Mg ha-1), SRM (15,4 Mg ha-1) and CC (3,4 Mg ha-1) plus a control treatment (no acidity correction), associated or not with agricultural gypsum (GA) (3,0 Mg ha-1). Unformed soil samples were collected in May 2021 (i) monoliths, in the layers 0 – 0,05; 0,05 – 010 and 0,10 – 0,20 m, for evaluation of aggregation and aggregate stability. Deformed samples were collected in layers 0 – 0,05; 0,05 – 0,10; 0,10 – 0.20; 0,20 – 0,40 and 0,40 – 0,60 m for determination of soil acidity components (pH, H+Al and Al3+), basic exchangeable cations (Ca2+, Mg2+ and K+) and labile carbon (COX-P) and organic carbon (CO) contents. The effect of reapplication of acidity correctives was more effective, increasing labile carbon content in the soil considering a 0 – 0,20 m layer. In the 0 – 0,05 m layer, labile carbon contents remained stable. The limestones when applied alone increased the availability of organic carbon in the soil. The reapplication of the acidity correctives and agricultural gypsum resulted in the reduction of the microaggregates class. The large, medium and small MAgg classes correlated with exchangeable acidity (Al3+) of the soil. On the other hand, microaggregates correlated with active acidity (pH), potential (H+Al) and with Mg2+. The correctives increased DMP and large MAgg in the 0 – 0,05 m layer. The effect of reapplication of the correctives and agricultural gypsum on soil acidity will be more evident at longer term of application, requiring further evaluation. The combination of ground rock limestone and calcined limestone with gypsum promoted better pH correction (active acidity) on the surface (0 – 0,20 m). Besides showing a positive effect (without or with gypsum) of gypsum on Ca2+ availability at the surface. Aggregate classes are strongly linked to soil chemical components and cations and soil organic carbon. The large MAgg class (macroaggregates) increases according to the application of acidity correctives without gypsum application. |

O objetivo geral deste estudo foi a avaliar reaplicação de corretivos de acidez do solo, calcário de rocha moída (CRM), silicato de rocha moída (SRM) e calcário calcinado (CC), associados ou não ao gesso agrícola (GA) sobre agregação do solo em sistema de plantio direto (SPD). O presente estudo foi conduzido na área experimental no Campo Demonstrativo Experimental (CDE) da Fundação ABC, na cidade de Ponta Grossa–PR, sobre um LATOSSOLO VERMELHO-AMARELO Distrófico de textura argilo-arenosa. Os tratamentos foram os três corretivos da acidez do solo CRM (4,8 Mg ha-1), SRM (15,4 Mg ha-1) e CC (3,4 Mg ha-1) mais um tratamento controle (sem correção da acidez), associados ou não ao gesso agrícola (GA) (3,0 Mg ha-1). Foram coletadas amostras indeformadas de solo em maio de 2021 (i) monólitos, nas camadas 0 – 0,05; 0,05 – 0,10 e 0,10 – 0,20 m, para avaliação da agregação e da estabilidade de agregados. As amostras deformadas foram coletadas nas camadas 0 – 0,05; 0,05 – 0,10; 0,10 – 0.20; 0,20 – 0,40 e 0,40 – 0,60 m, para determinação dos componentes da acidez do solo (pH, H+Al e Al3+), cátions básicos trocáveis (Ca2+, Mg2+ e K+) e teores de carbono lábil (COX-P) e orgânico (CO). O efeito da reaplicação dos corretivos da acidez foi mais eficaz, aumentando conteúdo de carbono “lábil” no solo considerando uma de 0 – 0,20 m. Na camada de 0-0,05 m, os teores de carbono “lábil” mantiveram-se estáveis. Os calcários quando aplicados isoladamente aumentaram na disponibilidade de carbono orgânico no solo. A reaplicação dos corretivos da acidez e do gesso agrícola resultou na redução da classe de microagregados. As classes de MAgg grandes, médios e pequenos correlacionaram-se com acidez trocável (Al3+) do solo. Por outro lado, os microagregados correlacionou-se com acidez ativa (pH), potencial (H+Al) e com Mg2+. Os corretivos aumentaram o DMP e MAgg grandes na camada de 0 – 0,05 m. O efeito da reaplicação dos corretivos e do gesso agrícola sobre acidez do solo será mais evidente a um maior longo prazo de aplicação, necessitando de posteriores avaliações. A combinação do calcário de rocha moída e calcário calcinado com o gesso agrícola, promoveu melhor correção do pH (acidez ativa) em superfície (0 – 0,20 m). Além de apresentar efeito positivo (Sem ou Com gesso) de gesso na disponibilidade de Ca2+ no em superfície. As classes de agregados estão fortemente ligadas aos componentes químicos do solo e dos cátions e ao carbono orgânico do solo. A classe MAgg grandes (macroagregados) aumenta conforme à aplicação dos corretivos da acidez sem aplicação de gesso agrícola.CAPESFUNDAÇÃO AGRISUSSul-1application/pdfapplication/pdfporUniversidade Federal do ParanáPrograma de Pós-Graduação em Ciência do SoloBrasilUniversidade Federal do ParanáAcid soilsChemical managementStabilitySoil structureSolos ácidosManejo químicoEstabilidadeEstrutura do soloCiência do SoloManejo e Conservação do SoloFertilidade do SoloFísica do SoloAgregação do solo sob os efeitos da reaplicação de corretivos da acidez e de gesso agrícola em plantio diretoSoil aggregation under the effects of reapplication of acidity correctives and agricultural gypsum in no-tillageinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Comum do Brasil - Depositainstname:Instituto Brasileiro de Informação em Ciência e Tecnologia (Ibict)instacron:IBICTTEXTRAFAELA_BEZERRA_DISSERTAÇÃO.pdf.txtWritten by FormatFilter org.dspace.app.mediafilter.TikaTextExtractionFilter on 2025-06-06T20:13:45Z (GMT).Extracted texttext/plain103380https://deposita.ibict.br/bitstreams/d4e8101f-7e3d-48ca-93bd-dcdc9a92f3ad/download0c597cd446ed202412198c5cf4dcdc4bMD53falseAnonymousREADTHUMBNAILRAFAELA_BEZERRA_DISSERTAÇÃO.pdf.jpgWritten by FormatFilter org.dspace.app.mediafilter.PDFBoxThumbnail on 2025-06-06T20:13:45Z (GMT).Generated Thumbnailimage/jpeg3851https://deposita.ibict.br/bitstreams/f54af3de-5747-4634-919b-d7badb3fc38d/download1d267496175c27cff6b5ae3b658007edMD54falseAnonymousREADLICENSElicense.txtWritten by org.dspace.content.LicenseUtilstext/plain; charset=utf-81867https://deposita.ibict.br/bitstreams/3b99b502-8047-4f46-8ffe-572d26d98c57/downloada7c148eec59885ba1ba6d14692be8465MD51falseAnonymousREADORIGINALRAFAELA_BEZERRA_DISSERTAÇÃO.pdf/dspace/deposita/upload/RAFAELA_BEZERRA_DISSERTAÇÃO.pdfDocumento oficial da dissertaçãoapplication/pdf1621546https://deposita.ibict.br/bitstreams/00dcdb48-e486-418c-a9e4-1bbe8fb93edf/download15330cfb3ee5ceaf83440e6a3b50378cMD52trueAnonymousREADdeposita/3922026-03-20T17:39:19.927587Zopen.accessoai:deposita.ibict.br:deposita/392https://deposita.ibict.brRepositório ComumPUBhttp://deposita.ibict.br/oai/requestdeposita@ibict.bropendoar:46582026-03-20T17:39:19Repositório Comum do Brasil - Deposita - Instituto Brasileiro de Informação em Ciência e Tecnologia (Ibict)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 |
