Resumo: | This study aimed to evaluate carbon and nitrogen stocks restoration, and soil fertility status in land reclamation with nodulated and mycorrhizal legume trees and fallow length on high productivity shifting cultivation. Evaluations were made of soil C and N stocks, concentration of free and occluded light fraction and soil available Ca, Mg, P, K, C and N, and amounts of mass and nutrients of litter in the dry and rainy season. One of the areas located in Angra dos Reis, RJ is under reclamation for 13 years. As reference area it was used a forest fragment and deforested area nearby. A second area is located in Serop?dica, RJ, and it is under reclamation for 17 years with the species Acacia auriculiformis and Mimosa caesalpiniifolia, and with Albizia guachapele for 13 years. As reference area it was used a secondary forest fragment and a pasture area. Both areas under recuperation in Angra dos Reis and in Serop?dica had been used as source of topsoil, having lost part of the upper soil horizons. The slash-and-burn area is located in Bom Jardim, Nova Friburgo, RJ. For this study, it was utilized a chronossequence of soil gradient: area cultivated for one year; area cultivated with crop rotation for three years; area cultivated with bananas for 18 years; area under fallowing for five years; and others two fallowing areas for 18 and 33 years. The usage of legume trees in land reclamation was able to increase stocks of C and N, from 0.04 to 0.15 Mg ha-1 year-1 for N, and of 0.13 to 1.73 Mg ha-1 year-1 for C. In the slash-and-burn agriculture system, the lowest soil C stock was found in the one and three years cultivated areas. The highest stock was observed under fallowing and in the area planted with bananas, and they were similar between areas. The highest soil N stock was found in fallow with five years. In Angra dos Reis area the concentration of free and occluded light fraction was similar between areas of forest and under reclamation. In Serop?dica, only the free light fraction of organic matter was re-established. There was no significant difference between the concentrations of free and occluded light fraction in Bom Jardim areas; however, the area with five years fallow and three years cultivation showed the same values of the free light fraction. In Angra dos Reis areas, the litter stocks were similar between the forest and the area under reclamation. In Serop?dica, except for the area under A.auriculiformis with greatest litter stock, all other areas showed similar litter stocks. In Bom Jardim, the litter stocks were similar among the fallowing areas. The nutrients contained in the litter, in general, were similar among the areas, and they were dependent on the litter mass. The soil fertility in the areas under reclamation was slightly higher than in the reference ones. In the slash-and-burn area, the soil fertility analyses indicated a residual effect of liming in the fallow with five years. Considering the attributes soil fertility and soil C and N stocks, the best fallowing period would be of five years. |

Foram avaliados os estoques de C e N do solo, as concentra??es de fra??o leve livre e leve oclusa da mat?ria org?nica, os teores de Ca, Mg, P, K, C e N no solo, e o estoque e a quantidade de nutrientes presentes na serapilheira nas esta??es seca e chuvosa. Uma das ?reas avaliadas, no munic?pio de Angra dos Reis (RJ), est? em recupera??o h? 13 anos. Para fins de compara??o, utilizou-se como refer?ncia uma ?rea de mata e outra, desmatada, adjacente ? ?rea em recupera??o. As demais ?reas estudadas localizam-se em Serop?dica (RJ), e est?o em recupera??o h? 17 anos com as esp?cies Mimosa caesalpiniifolia e Acacia auriculiformis, e h? 13 anos, com a esp?cie Albizia guachapele. Como ?rea refer?ncia foi utilizada uma ?rea de capoeira e outra de pastagem. Tanto a ?rea em recupera??o localizada em Angra dos Reis quanto as ?reas em recupera??o em Serop?dica haviam sido utilizadas como ?reas de empr?stimo, tendo perdido parte dos horizontes superficiais do solo. A ?rea de agricultura itinerante situa-se em Bom Jardim, regi?o serrana do Rio de Janeiro. Foi avaliado um gradiente de uso do solo: ?rea cultivada h? um ano; ?rea h? tr?s anos com rota??o cultivos; ?rea h? 18 anos cultivada com bananas; ?rea em pousio h? cinco anos; e outras duas ?reas em pousio h? 18 e 33 anos. O uso de leguminosas incrementou os estoques de C e N do solo nas ?reas em recupera??o. As taxas de aumento variaram de 0,04 a 0,15 Mg ha-1 ano-1 para N, e de 0,13 a 1,73 Mg ha-1 ano-1 de C. No sistema de agricultura itinerante, os menores estoques de C foram observados nas ?reas cultivadas h? um e h? tr?s anos. Nas ?reas em pousio e no bananal os estoques foram similares entre si e superiores aos das ?reas cultivadas. O maior estoque de N foi observado na ?rea com cinco anos de pousio. As concentra??es de fra??o leve livre e leve oclusa foram similares entre as ?reas de mata e em recupera??o em Angra dos Reis. Nas ?reas em recupera??o em Serop?dica, somente a fra??o leve livre foi restabelecida. J? nas ?reas de Bom Jardim, n?o houve diferen?a significativa entre as concentra??es de fra??o leve livre e leve oclusa. No entanto, o pousio de cinco anos e o cultivo de tr?s anos apresentaram os menores valores de fra??o leve livre. Os estoques de serapilheira nas ?reas de mata e em recupera??o de Angra dos Reis foram similares. As ?reas em recupera??o no munic?pio de Serop?dica apresentaram estoques de serapilheira similares, com exce??o da esp?cie A. auriculiformis que mostrou os maiores estoques. Nas ?reas em pousio do sistema de agricultura itinerante, os estoques de serapilheira foram similares. O estoque de nutrientes da serapilheira, em geral, variou pouco, e foi dependente da massa de serapilheira. A fertilidade dos solos das ?reas em recupera??o foi ligeiramente maior que das ?reas refer?ncia. Na agricultura itinerante, pode-se observar efeito residual da calagem usada pelo agricultor no pousio de cinco anos. De acordo com os resultados de estoque de C, N e fertilidade do solo, o per?odo de pousio mais indicado para o corte e queima foi o de cinco anos.CNPq - Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gicoapplication/pdfhttps://tede.ufrrj.br/retrieve/13354/2007%20-%20Michele%20de%20Oliveira%20Macedo.pdf.jpghttps://tede.ufrrj.br/retrieve/18184/2007%20-%20Michele%20de%20Oliveira%20Macedo.pdf.jpghttps://tede.ufrrj.br/retrieve/24518/2007%20-%20Michele%20de%20Oliveira%20Macedo.pdf.jpghttps://tede.ufrrj.br/retrieve/30927/2007%20-%20Michele%20de%20Oliveira%20Macedo.pdf.jpghttps://tede.ufrrj.br/retrieve/37283/2007%20-%20Michele%20de%20Oliveira%20Macedo.pdf.jpghttps://tede.ufrrj.br/retrieve/43627/2007%20-%20Michele%20de%20Oliveira%20Macedo.pdf.jpghttps://tede.ufrrj.br/retrieve/50009/2007%20-%20Michele%20de%20Oliveira%20Macedo.pdf.jpghttps://tede.ufrrj.br/retrieve/56466/2007%20-%20Michele%20de%20Oliveira%20Macedo.pdf.jpgporUniversidade Federal Rural do Rio de JaneiroPrograma de P?s-Gradua??o em Agronomia - Ci?ncia do SoloUFRRJBrasilInstituto de Agronomiaciclagem de nutrientesfixa??o biol?gica de nitrog?niofungos micorr?zicosserapilheiranutrient cyclingbiological nitrogen fixationmycorrhizal fungilitterAgronomiaEstoque de carbono, nitrog?nio e fertilidade do solo em ?reas em recupera??o com leguminosas e em sistema de agricultura itinerante de alta produtividadeSoil carbon and nitrogen stocks and fertility in areas in recuperation with leguminous trees and on shifting cultivation system area with high productivityinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações da UFRRJinstname:Universidade Federal Rural do Rio de Janeiro (UFRRJ)instacron:UFRRJTHUMBNAIL2007 - Michele de Oliveira Macedo.pdf.jpg2007 - Michele de Oliveira Macedo.pdf.jpgimage/jpeg1943http://localhost:8080/tede/bitstream/tede/319/17/2007+-+Michele+de+Oliveira+Macedo.pdf.jpg8c1280dca4077478b5fad29883580c72MD517TEXT2007 - Michele de Oliveira Macedo.pdf.txt2007 - Michele de Oliveira Macedo.pdf.txttext/plain243914http://localhost:8080/tede/bitstream/tede/319/16/2007+-+Michele+de+Oliveira+Macedo.pdf.txt83a47dd7940034a0c398cf221f8630f8MD516ORIGINAL2007 - Michele de Oliveira Macedo.pdf2007 - Michele de Oliveira Macedo.pdfapplication/pdf1438251http://localhost:8080/tede/bitstream/tede/319/1/2007+-+Michele+de+Oliveira+Macedo.pdf6f18c3a98c95797b06ec0bc1e7b7ec2cMD51tede/3192022-06-13 12:46:02.447oai:localhost:tede/319Biblioteca Digital de Teses e Dissertaçõeshttps://tede.ufrrj.br/PUBhttps://tede.ufrrj.br/oai/requestbibliot@ufrrj.br||bibliot@ufrrj.bropendoar:2022-06-13T15:46:02Biblioteca Digital de Teses e Dissertações da UFRRJ - Universidade Federal Rural do Rio de Janeiro (UFRRJ)false |

This study aimed to evaluate carbon and nitrogen stocks restoration, and soil fertility status in land reclamation with nodulated and mycorrhizal legume trees and fallow length on high productivity shifting cultivation. Evaluations were made of soil C and N stocks, concentration of free and occluded light fraction and soil available Ca, Mg, P, K, C and N, and amounts of mass and nutrients of litter in the dry and rainy season. One of the areas located in Angra dos Reis, RJ is under reclamation for 13 years. As reference area it was used a forest fragment and deforested area nearby. A second area is located in Serop?dica, RJ, and it is under reclamation for 17 years with the species Acacia auriculiformis and Mimosa caesalpiniifolia, and with Albizia guachapele for 13 years. As reference area it was used a secondary forest fragment and a pasture area. Both areas under recuperation in Angra dos Reis and in Serop?dica had been used as source of topsoil, having lost part of the upper soil horizons. The slash-and-burn area is located in Bom Jardim, Nova Friburgo, RJ. For this study, it was utilized a chronossequence of soil gradient: area cultivated for one year; area cultivated with crop rotation for three years; area cultivated with bananas for 18 years; area under fallowing for five years; and others two fallowing areas for 18 and 33 years. The usage of legume trees in land reclamation was able to increase stocks of C and N, from 0.04 to 0.15 Mg ha-1 year-1 for N, and of 0.13 to 1.73 Mg ha-1 year-1 for C. In the slash-and-burn agriculture system, the lowest soil C stock was found in the one and three years cultivated areas. The highest stock was observed under fallowing and in the area planted with bananas, and they were similar between areas. The highest soil N stock was found in fallow with five years. In Angra dos Reis area the concentration of free and occluded light fraction was similar between areas of forest and under reclamation. In Serop?dica, only the free light fraction of organic matter was re-established. There was no significant difference between the concentrations of free and occluded light fraction in Bom Jardim areas; however, the area with five years fallow and three years cultivation showed the same values of the free light fraction. In Angra dos Reis areas, the litter stocks were similar between the forest and the area under reclamation. In Serop?dica, except for the area under A.auriculiformis with greatest litter stock, all other areas showed similar litter stocks. In Bom Jardim, the litter stocks were similar among the fallowing areas. The nutrients contained in the litter, in general, were similar among the areas, and they were dependent on the litter mass. The soil fertility in the areas under reclamation was slightly higher than in the reference ones. In the slash-and-burn area, the soil fertility analyses indicated a residual effect of liming in the fallow with five years. Considering the attributes soil fertility and soil C and N stocks, the best fallowing period would be of five years. |
