Resumo: | The chemical characteristics of earthworm casts and a soil sample from a commercial plantation of Eucalyptus grandis aged 3 years old near the city of Mogi-Guaçu in the State of São Paulo, Brazil, were compared. The casts were collected at the surface of the mineral soil, while the soil was collected at depths of 0 - 5; 5 - 10; 10 - 20 and 20 - 30 cm. The Ca+2 and Mg+2 contents of casts, in comparison to the 0 to 5 cm soil depth, were 11 times higher,while the K+ contents were 3 times higher. In addition, the cation exchange capacity (CEC) and C contents were 4.41 and 2.83 more concentrated in the casts, respectively. It was observed a decrease in Aluminum saturation (m%) from 73%, in the depth of the 0-5 cm, to 45% in the casts. While the chemical characteristics of the native earthworm casts represent a distinct improvement over the soil, it remains to be seen what influence, if any, this has on the growth and nutrition of E. grandis. |

Os excrementos foram separados da superfície do solo com o auxílio de uma espátula, enquanto que as amostras do solo foram coletadas nas profundidades 0-5; 5-10; 10-20 e 20-30cm. Os teores de Ca+2 e Mg+2 trocáveis nos excrementos foram 11 vezes superiores aos determinados na profundidade de 0-5 cm, enquanto os teores de K+ foram 3 vezes superiores. Os valores da CTC e do Carbono nos excrementos foram, respectivamente, 4,41 e 2,83 vezes superiores aos observados no solo,na profundidade de 0-5 cm de solo. Constatou-se também que a saturação por Al (m%) diminuiu de 73% no solo, na profundidade de 0-5 cm, para 45% nos excrementos. Embora as características químicas dos excrementos de minhocas tenham sido melhores que aquelas observadas no solo, sua influência na nutrição e no crescimento do E. grandis precisa ser estudada.Embrapa Florestas2002-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1748Pesquisa Florestal Brasileira; n. 45 (2002): jul./dez.; 29-39Pesquisa Florestal Brasileira; No. 45 (2002): jul./dez.; 29-391983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1748/679Quadros, Ruth Maria Bianchini deBellote, Antonio Francisco JuradoDionísio, Jair Alvesinfo:eu-repo/semantics/openAccess2018-11-30T16:01:20Zoai:pfb.cnpf.embrapa.br/pfb:article/1748Revistahttps://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:2018-11-30T16:01:20Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
