Resumo: | Knowledge of physical and chemical properties of soil under forest islands, embedded in savanna ecosystems is fundamental to its sustainable use and to understand its origin. This study aimed to identify the soil influence the occurrence of forest islands in Savannah. The study was conducted on four Islands Forestry (IF) and Savanna (S) adjacent, located in northeastern Roraima. Each Island Forest transects were established in the east - west and north - south, along which the trenches were opened in May. Since, for each class of land identified, was an open trench of 200 cm depth as modal. The other, 40 cm. These trenches were collected and undisturbed samples at depths from 00 to 10 cm, 10-20 cm and 20-40 cm. The soil samples were used to study the density of the soil, while disturbed samples for physical and chemical analysis. We established a transect bypassing each Island Forest (IF), a distance of 100 meters from the border, to minimize the effects of the transition. Along this transect, five trenches were opened halfway, and was employed the same method used to collect data on forest islands. Data were obtained from both physical and chemical environments. The data were selected and treated statistically by analysis of variance (ANOVA). Prevailed in the islands forest soils with colors red, yellow, yellow-red as prevailed in the savanna soil with burnished colors and yellow. The highest values of soil density and penetration resistance were observed in soils under savanna (S), while higher moisture values were found in Forest Islands (FI). For soil chemical properties were observed in the highest values of calcium, magnesium, potassium, phosphorus, total bases, cation exchange capacity, total effective cation exchange capacity, base saturation and organic matter in soils under forest, while the savannah showed higher concentrations of aluminum and aluminum saturation increased. The results indicated better physical and chemical conditions in soils under forest islands. The soils under (S) are undernourished while in the islands are eutrophic, with the exception of (IF1). As the organic matter content of the factor determining factor for the soil conditions of the islands. In this study, the dominant soil class in the study area was followed by Ultisols and Oxisols Plinthosols. The taxonomic classification to the first category level does not explain the occurrence of forest islands embedded in the savanna. |

Este trabalho teve como objetivo identificar a influência do solo na ocorrência de Ilhas Florestais em Savana. O estudo foi conduzido em quatro Ilhas Florestais (IF) e Savana (S) contígua, localizadas no nordeste de Roraima. Em cada Ilha Florestal, foram estabelecidos transectos no sentido leste – oeste e norte – sul, ao longo dos quais foram abertas 5 trincheiras. Sendo que, para cada classe de solo identificada, foi aberta uma trincheira de 200 cm de profundidade como modal. As demais, com 40 cm. Nestas trincheiras foram coletadas amostras indeformadas e deformadas nas profundidades de 0 – 10 cm, 10 – 20 cm e de 20 – 40 cm. As amostras indeformadas foram utilizadas para estudo de densidade dos solos, enquanto as amostras deformadas, para análises físicas e químicas. Foi estabelecido um transecto contornando cada Ilha Florestal (IF), a uma distância de 100 m de sua borda, para minimizar os efeitos da transição. Ao longo deste transecto, foram abertas 5 trincheiras equidistantes, e foi empregado o mesmo método de coleta utilizado nas ilhas florestais. Obtiveram-se dados físicos e químicos dos dois ambientes. Os dados obtidos foram selecionados e tratados estatisticamente por meio de análise de variância (ANOVA). Nas ilhas florestais prevaleceram os solos com cores avermelhadas, amareladas, amarelo-avermelhadas enquanto nas savanas prevaleceram os solos com cores brunadas e amareladas. Os maiores valores de densidade do solo e resistência mecânica à penetração foram observados nos solos sob Savana (S), enquanto os maiores valores de umidade foram verificados nas Ilhas Florestais (IF). Para as características químicas avaliadas observaram-se os maiores valores de cálcio, magnésio, potássio, fósforo, soma de bases, capacidade de troca catiônica total, capacidade de troca catiônica efetiva, saturação por bases e matéria orgânica nos solos sob floresta, enquanto a savana apresentou maior concentração de alumínio e maior saturação por alumínio. Os resultados indicaram melhores condições físicas e químicas nos solos sob Ilhas florestais. Os solos sob savana são distróficos enquanto sob as ilhas são eutróficos, com exceção da (IF1). Sendo o teor de matéria orgânica o fator determinante para as condições dos solos das ilhas. Neste estudo, a classe de solo dominante nas áreas estudadas foi o Latossolos seguido de Argissolos e Plintossolos. A classificação taxonômica até o primeiro nível categórico não explica a ocorrência das ilhas florestais inseridas nas áreas de savana.Universidade Federal de RoraimaBrasilPRPPG - Pró-Reitoria de Pesquisa e Pós-GraduaçãoPRONAT - Programa de Pós-Graduação em Recursos NaturaisUFRRVale Júnior, José Frutuoso dohttp://lattes.cnpq.br/3469234866298985Feitosa, Keily Katiany Almeida2020-05-18T23:46:24Z2020-05-18T23:46:24Z2009info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisFEITOSA, Keily Katiany Almeida.
