Sistematiza??o de experi?ncias na implanta??o de sistemas agroflorestais no dom?nio da Mata Atl?ntica / Experiences systematization in the establishment of agroforestry systems at the Atlantic Forest domain

No. of bitstreams: 1 2013 - Bernardo Milward de Azevedo Spinelli.pdf: 2468118 bytes, checksum: 8b86d55b4fe024e0a43e7aca610af976 (MD5) Previous issue date: 2013-12-19 / The Brazilian New Forestry Law establishes a farmer?s commitment with environmental adequacy of its properties. The Permanent Preservation Areas, currently used in the properties with crops and pastures in many cases need to a restauration techniques. The new law allows the exploration of agroforestry systems (AFS) even in areas of permanent preservation, since do not mischaracterize the native preexisting vegetation either not being detrimental to environmental function to protecting water springs, erosion protection and increasing biodiversity. This study aimed to systematize the author's personal experiences with agroforestry systems in the Atlantic Forest domain regions and show different techniques and implantation strategies and management of agroforestry systems that can be employed day to day by farmers, especially the small family farmer. The different AFS deployed were based on biodiversity and plant succession, with low use of inputs and capital resources. The structure of the recommended systems was grounded on labor, family labor, in multistrata systems and the use of common plants in each location with high biomass production potential to enhance nutrient cycling. On average, more than 30 species were introduced in each AFS and the issues related to the choice of species to plant recognizing the soil quality from indicator plants were discussed. In addition, how to plan and distribute the plants in agroforestry designs were also described in detail. The best ways of how to plant and manage, with pruning, different species in biodiverse agroforestry systems included in this dissertation were presented from about 20 years of the author's experience in order to assist all those interested in working with this theme. / O Novo C?digo Florestal estabelece o compromisso por parte dos produtores rurais com a adequa??o ambiental de suas propriedades. As ?reas de Preserva??o Permanente, hoje utilizadas nas propriedades para cultivos agr?colas e pastagens, em muitos casos necessitar?o ser recuperadas. A nova lei permite a explora??o de sistemas agroflorestais (SAFs) at? mesmo em ?reas de preserva??o permanente, desde que n?o descaracterize a cobertura vegetal nativa existente e nem prejudique a fun??o ambiental da ?rea, protegendo nascentes, combatendo a eros?o e aumentando a biodiversidade. O presente trabalho teve como objetivo sistematizar experi?ncias pessoais do autor com sistemas agroflorestais em regi?es de dom?nio da Mata Atl?ntica, mostrando diferentes t?cnicas e estrat?gias de implanta??o e manejo de SAFs que podem ser empregadas no dia a dia dos produtor rural, principalmente, do pequeno agricultor familiar. Os diferentes SAFs implantados foram baseados na biodiversidade e sucess?o vegetal, com baixo uso de insumos e recursos de capital. A estrutura dos sistemas preconizados foi alicer?ada na m?o-de-obra familiar, em multiestratos, na utiliza??o de plantas comuns em cada localidade com potencial de produ??o de biomassa, para intensificar a ciclagem de nutrientes. Em m?dia mais de 30 esp?cies eram introduzidas em cada SAF e as quest?es relacionados com a escolha das esp?cies, onde plantar reconhecendo a qualidade do solo a partir de plantas indicadoras foram abordadas. Al?m disso, como planejar e distribuir as plantas em desenhos agroflorestais tamb?m foram processos detalhadamente descritos. As melhores formas de como plantar e manejar, com podas, as diferentes esp?cies nos SAFs biodiversos constam desta disserta??o e foram apresentados a partir de cerca de 20 anos de experi?ncia do autor com intuito de auxiliar todos aqueles interessados em trabalhar com tem?tica.
