Resumo: | The objective of this work was to estimate organic C storage rates in an Typic Hapludox fertilized with soluble fertilizer and pig slurry and cropped under no‑tillage. The experiment was carried out in the municipality of Campos Novos, in the state of Santa Catarina, Brazil, and the following treatments were applied annually: no fertilization; soluble fertilizer; 25 m3 ha‑1 pig slurry + soluble fertilizer; and rates of 25, 50, 100, and 200 m3 ha‑1 pig slurry. The following were determined: organic carbon (OC) stocks in the 0–20 cm soil layer; C inputs by crop biomass and pig slurry; annual C fixation rates; and the soil OC humification (k1) and mineralization (k2) coefficients. The real and apparent C fixation rates increased according to pig slurry rates, ranging from 0.6 to 1.7 and from 0.05 to 1.0 Mg ha‑1 per year, respectively. The k1 and k2 coefficients were 0.17 and 0.011, respectively, whereas the C input required to maintain the initial stock of OC is of 4.14 Mg ha‑1 per year. Pig slurry applied annually on a Typic Hapludox cropped with the maize‑black oat succession under no‑tillage increases soil OC in rates of up to 200 m3 ha‑1. |

O experimento foi conduzido em Campos Novos, SC, e os seguintes tratamentos foram aplicados anualmente: sem adubação; adubo solúvel; 25 m3 ha‑1 de dejeto líquido + adubo solúvel; e doses de 25, 50, 100 e 200 m3 ha‑1 de dejeto líquido. Foram determinados: os estoques de C orgânico (CO) na camada de 0–20 cm do solo; a adição de C pela fitomassa dos cultivos e pelo dejeto líquido de suíno; as taxas anuais de fixação de C; e os coeficientes de humificação (k1) e de mineralização (k2) de CO do solo. As taxas de fixação de C real e aparente aumentaram de acordo com as doses de dejeto, tendo variado de 0,6 a 1,7 e de 0,05 a 1,0 Mg ha‑1 por ano, respectivamente. Os coeficientes k1 e k2 foram 0,17 e 0,011, respectivamente, enquanto o aporte de C requerido para manter o estoque inicial de CO do solo é de 4,14 Mg ha‑1 por ano. O dejeto líquido de suíno aplicado anualmente em Latossolo Vermelho cultivado com a sucessão milho‑aveia‑preta em plantio direto aumenta o CO do solo em doses de até 200 m3 ha‑1.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraUDESC e CAPESMafra, Maria Sueli HeberleCassol, Paulo CezarAlbuquerque, Jackson AdrianoCorrea, Juliano CorulliGrohskopf, Marco AndréPanisson, Jonas2014-08-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/19047Pesquisa Agropecuaria Brasileira; v.49, n.8, ago. 2014; 630-638Pesquisa Agropecuária Brasileira; v.49, n.8, ago. 2014; 630-6381678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/19047/12754https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/19047/11405info:eu-repo/semantics/openAccess2014-10-13T16:23:19Zoai:ojs.seer.sct.embrapa.br:article/19047Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-13T16:23:19Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
