Resumo: | The adequate soil usage and management affect directly its quality, and they are fundamental aspects in the development of a sustainable agriculture. The objective of this study was to evaluate the influence of agricultural organic systems in the different organic matter fractions and soil aggregation, and to correlate them with changes in physical and chemical properties of an Udult soil. The study was developed in an area of the Integrated System of Agroecological Production (SIPA), located in Serop?dica, Rio de Janeiro State, Brazil. The plots selected presented the following cultivation and crops treatments: conventional tillage (corn/beans), no tillage (eggplant/corn), passion fruit and Desmodium sp consortium, fig cultivation, and agroforest system (AFS). The soil samples were taken in two depths (0-5 and 5-10 cm) and two periods of the year, the first in November 2005 (summer) and the second in June 2006 (winter). The physical properties analyzed were: bulk density (Ds), particle density (Dp), granulometry, total volume of pores (VTP%), aggregate stability by the considered mean weight diameter (DMP) and mean geometric diameter (GMD) indexes; and granulometric fractioning of soil organic matter, obtaining the particulate organic carbon organic (COp) and minerals associated organic carbon (COam). The chemical analyses consisted of: total organic carbon (TOC), and chemical fractioning of soil organic matter, with determination of organic carbon in humin (C-HUM), humic acids (C-FAH) and fulvic acids (C-FAF) fractions. They were calculated the carbon stocks in the chemical and physical fractions of the soil organic matter. In relation to the physical properties, the soil texture was sandy loam, in all areas and sampled depths, and the Ds values did not indicate restriction to root development of the crops. The area with conventional tillage and corn/beans presented the smallest DMP and GMD values. In the summer season, the largest DMP and GMD values were verified in the 0-5 cm superficial layer. While in the 5-10 cm depth, the largest values were found in the winter season. The COp was more adequate than TOC to evidence differences among the crops and agroecological systems, when analyzed the 0-5 cm depth and in the summer season. The COam presented differences among the areas in the two evaluated depths. The management systems adopted in the SIPA, in each soil sampling season, influenced TOC levels, mainly in the 5-10 cm depth. The C-HUM was the fraction that contributed to most of the TOC, standing out in the area under fig coverage, in both depths and in summer. By using the average values of C-FAH it was possible to identify alterations in the soil related to the agroecological management, in the surface layer and for the summer season sampling, for all the crops and systems. Standing out that in the no tillage system, where the contents of C-FAH were largest, in the two depths, when compared to the area with conventional tillage. The C-FAF presented this same behavior, only that for the depth of 5-10 cm and in the winter, especially for the area with conventional tillage, with largest content of that fraction when compared to the no tillage system. |

O objetivo deste trabalho foi avaliar a influ?ncia de sistemas de manejo agr?cola org?nico nas diferentes fra??es da mat?ria org?nica e agrega??o do solo, e correlacion?-las com mudan?as nas propriedades f?sicas e qu?micas de um ARGISSOLO VERMELHO-AMARELO. O trabalho foi realizado na ?rea do Sistema Integrado de Produ??o Agroecol?gica (SIPA), localizada em Serop?dica, RJ. As glebas selecionadas apresentavam as seguintes formas de cultivo e cobertura vegetal: preparo convencional (milho/feij?o), sistema plantio direto (berinjela/milho), cons?rcio maracuj? - Desmodium sp, uma ?rea cultivada com figo e um sistema agroflorestal (SAF). As amostras de terra foram coletadas em duas profundidades (0-5 e 5-10 cm) e em duas ?pocas, sendo a primeira em novembro de 2005 (ver?o) e a segunda em junho de 2006 (inverno). Foram avaliadas as propriedades f?sicas: densidade do solo (Ds), densidade das part?culas (Dp), granulometria, volume total de poros (VTP%), estabilidade de agregados atrav?s dos ?ndices de di?metro m?dio ponderado (DMP) e di?metro m?dio geom?trico (DMG); e fracionamento granulom?trico da mat?ria org?nica do solo (MOS), obtendo-se o carbono org?nico particulado (COp) e carbono org?nico associado aos minerais (COam). As an?lises qu?micas consistiram de: carbono org?nico total (COT) e fracionamento qu?mico da MOS, quantificando-se o carbono das fra??es humina (C-HUM), ?cidos h?micos (C-FAH) e ?cidos f?lvicos (C-FAF). Foram calculados os estoques de carbono das fra??es qu?micas e f?sicas da MOS. Em rela??o ?s propriedades f?sicas, a textura encontrada foi franco-arenosa, em todas as ?reas e profundidades amostradas, e os valores de Ds encontrados n?o indicaram restri??o ao desenvolvimento radicular das culturas. A ?rea sob cultivo de milho/feij?o em sistema convencional apresentou os menores valores de DMP e DMG. Na esta??o do ver?o verificaram-se maiores valores de DMP e DMG na profundidade de 0-5 cm, enquanto que na profundidade de 5-10 cm, estes maiores valores foram encontrados na esta??o do inverno. O COp mostrou-se mais eficiente que o COT, na esta??o do ver?o, para evidenciar diferen?as entre as coberturas vegetais sob sistema agroecol?gico, na profundidade de 0-5 cm. O COam apresentou diferen?as entre as ?reas nas duas profundidades avaliadas. Os sistemas de manejo adotados no SIPA, em cada ?poca de coleta de solo, influenciaram os teores de COT, principalmente na profundidade de 5-10 cm. O C-HUM foi ? fra??o que constituiu a maior parte do COT, destacando-se a ?rea com cobertura de figo, nas duas profundidades e no ver?o. Por meio dos valores de C-FAH foi poss?vel identificar altera??es no solo relacionadas ao manejo agroecol?gico, na camada superficial e no per?odo do ver?o, entre todas as ?reas e sistemas de cultivo. Destacando-se que no sistema plantio direto, os teores de C-FAH foram maiores, nas duas profundidades, quando comparado ? ?rea com preparo convencional do solo. J? o C-FAF apresentou este mesmo comportamento, s? que para a profundidade de 5-10 cm e no inverno, destacando-se o preparo convencional do solo, com maiores teores dessa fra??o quando comparado ao sistema plantio direto.Made available in DSpace on 2016-04-26T19:36:53Z (GMT).

The adequate soil usage and management affect directly its quality, and they are fundamental aspects in the development of a sustainable agriculture. The objective of this study was to evaluate the influence of agricultural organic systems in the different organic matter fractions and soil aggregation, and to correlate them with changes in physical and chemical properties of an Udult soil. The study was developed in an area of the Integrated System of Agroecological Production (SIPA), located in Serop?dica, Rio de Janeiro State, Brazil. The plots selected presented the following cultivation and crops treatments: conventional tillage (corn/beans), no tillage (eggplant/corn), passion fruit and Desmodium sp consortium, fig cultivation, and agroforest system (AFS). The soil samples were taken in two depths (0-5 and 5-10 cm) and two periods of the year, the first in November 2005 (summer) and the second in June 2006 (winter). The physical properties analyzed were: bulk density (Ds), particle density (Dp), granulometry, total volume of pores (VTP%), aggregate stability by the considered mean weight diameter (DMP) and mean geometric diameter (GMD) indexes; and granulometric fractioning of soil organic matter, obtaining the particulate organic carbon organic (COp) and minerals associated organic carbon (COam). The chemical analyses consisted of: total organic carbon (TOC), and chemical fractioning of soil organic matter, with determination of organic carbon in humin (C-HUM), humic acids (C-FAH) and fulvic acids (C-FAF) fractions. They were calculated the carbon stocks in the chemical and physical fractions of the soil organic matter. In relation to the physical properties, the soil texture was sandy loam, in all areas and sampled depths, and the Ds values did not indicate restriction to root development of the crops. The area with conventional tillage and corn/beans presented the smallest DMP and GMD values. In the summer season, the largest DMP and GMD values were verified in the 0-5 cm superficial layer. While in the 5-10 cm depth, the largest values were found in the winter season. The COp was more adequate than TOC to evidence differences among the crops and agroecological systems, when analyzed the 0-5 cm depth and in the summer season. The COam presented differences among the areas in the two evaluated depths. The management systems adopted in the SIPA, in each soil sampling season, influenced TOC levels, mainly in the 5-10 cm depth. The C-HUM was the fraction that contributed to most of the TOC, standing out in the area under fig coverage, in both depths and in summer. By using the average values of C-FAH it was possible to identify alterations in the soil related to the agroecological management, in the surface layer and for the summer season sampling, for all the crops and systems. Standing out that in the no tillage system, where the contents of C-FAH were largest, in the two depths, when compared to the area with conventional tillage. The C-FAF presented this same behavior, only that for the depth of 5-10 cm and in the winter, especially for the area with conventional tillage, with largest content of that fraction when compared to the no tillage system. |
