In this context, there is the need to adopt the use and sustainable management of land systems. The study aimed to evaluate what is forest restoration system more efficient degraded areas, based on the potential recovery of physical, chemical, carbon and biological activity in the soil. The work was conducted in a forest restoration area UTFPR- Campus two neighbors, whose experiment was established in October 2010. The experimental design is completely randomized, with four replications and experimental plot of 40 m wide by 54 m long ( 2160 m2) were collected and six sampling points per plot. The soil is classified as a Typic. The models evaluated are: 1 - natural or passive regeneration; 2 - Nucleation; 3 - Planting trees in the total area under lines fill and diversity (total planting); 4 - Reference area (forest). The collection of soil samples in layers of 0.0-0.05, 0.05-0.10, 0.10-0.20 and 0.20-0.40 m was carried out in October 2013 and evaluated physical attributes of texture, bulk density, total porosity, microporosity and soil macroporosity and stability of water in households, chemical properties, and total organic carbon (TOC) and physical particle size fractionation and soil biological activity. To find the best forest restoration model, we designed a Restoration Quality Weighted Index for each variable analyzed. Natural regeneration and total plantation showed generally better soil aggregation over 0.10 m and nucleation volume of similar porosity the forest for these layers. There were no differences between the models below 0.10 m for the variables aggregation and soil porosity. The nucleation template had the lowest bulk density, but being greater than the density in the layer forest 0.05-0.10 m, however, was similar to below 0.10 m above the ground. The models had chemical properties similar to or greater than the forest. The forest had the highest stock of COT and carbon associated with minerals (CAM), but natural regeneration was similar to the particulate organic carbon (POC) in the superficial layers of the soil (0-0.10 m), below 0, 10 m, the forest showed higher stock of COT and COP on the ground. The highest peak of C-CO2 emissions occurred in the 28-35 day range where the total plantation was similar to forest. After four years of experiments, it was found that the effect of restoration methods on physical attributes and soil carbon restricted to 0.10 m deep. CAPES A substituição da vegetação nativa por outros usos do solo é um dos principais agentes degradantes do ecossistema, sendo ele o mais importante componente dos ambientes terrestres, naturais ou com diferentes níveis de antropização, além de ser o principal substrato utilizado pelas plantas para obtenção de condições edáficas para seu desenvolvimento. Nesse contexto, tem-se a necessidade de adotar sistemas de uso e manejos sustentáveis da terra. O estudo teve como objetivo avaliar qual é sistema de restauração florestal de áreas degradada mais eficiente, com base no potencial de recuperação dos atributos físicos, químicos, carbono e atividade biológica no solo. O trabalho foi conduzido em uma área de restauração florestal na UTFPR- Câmpus dois vizinhos, cujo experimento foi implantado em outubro de 2010. O delineamento experimental é inteiramente casualizado, com quatro repetições e parcela experimental de 40 m de largura por 54 m de comprimento (2160 m2) e foram coletados seis pontos amostrais por parcela. O solo é classificado como um Latossolo Vermelho. Os modelos avaliados são: 1 - Regeneração natural ou passiva; 2 - Nucleação; 3 - Plantio de árvores em área total sob linhas de preenchimento e diversidade (Plantio total); 4 – área de Referência (floresta). A coleta das amostras de solo nas camadas de 0,0-0,05, 0,05-0,10, 0,10-0,20 e 0,20-0,40 m foi realizada em outubro de 2013 e avaliados os atributos físicos de textura, densidade do solo, porosidade total, microporosidade e macroporosidade do solo e estabilidade de agregados em água, atributos químicos, além de carbono orgânico total do solo (COT) e fracionamento físico granulométrico e atividade biológica do solo. Para encontrar o melhor modelo de restauração florestal, foi elaborado um Índice Ponderado de Qualidade de Restauração para cada variável analisada. A regeneração natural e o Plantio total apresentaram de modo geral a melhor agregação do solo acima de 0,10 m e a nucleação volume de porosidade similar a floresta para essas camadas. Não ocorreram diferenças entre os modelos abaixo de 0,10 m para as variáveis de agregação e porosidade do solo. O modelo nucleação apresentou a menor densidade do solo, mas sendo superior a densidade da floresta na camada 0,05-0,10 m, no entanto, foi similar abaixo de 0,10 m do solo. Os modelos apresentaram atributos químicos similar ou maior que a floresta. A floresta apresentou o maior estoque de COT e carbono associado aos minerais (CAM), mas, a regeneração natural foi similar para o carbono orgânico particulado (COP) nas camadas superficiais do solo (0-0,10 m), abaixo dos 0,10 m, a floresta apresentou maior estoque de COT e COP no solo. O maior pico de emissões de C-CO2 ocorreu no intervalo de 28-35 dias onde o Plantio total foi similar a floresta. Após quatro anos de experimento, verificou-se que o efeito dos modelos de restauração florestal nos atributos físicos e carbono do solo se restringem até 0,10 m de profundidade. 2016-10-14T16:35:05Z 2016-10-14T16:35:05Z 2016-03-23 masterThesis BALIN, Nilson Marcos.
