Carvão pirogênico como condicionante para substrato de mudas de <i>Tachigali vulgaris</i> L.G. Silva & H.C. Lima

Abstract: RESUMOEste estudo teve como objetivo verificar a eficiência de carvão vegetal pirogênico como condicionante de substrato para o desenvolvimento de mudas florestais de alto vigor, testando-se o carvoeiro (Tachigali vulgaris) como espécie representativa do Bioma Cerrado. Foram tomados como modelo de produtividade os solos de elevada capacidade de troca catiônica com Horizonte A antrópico da Amazônia (Terras Pretas de Índio), ricos em carbono pirogênico derivado de carvão vegetal. O experimento foi realizado no v… Show more

“…Some results can be distinct due to the chemical characteristics of the base substrate, which may be adequate to act on the available nutrient retention and promote the improvement of plant development without the need for addiction of an extra source of nutrients. In a work made with seedlings of Tachigali paniculata, a Brazilian tree species, the addition of biochar in varied doses to the substrate was found to promote improvement in the seedlings development (SOUCHIE et al, 2011), differently from the results observed here, where biochar benefited the seedlings development only related to cattle manure.…”

“…Conforme a Tabela 1 observa-se que houve diferenças entre os substratos para os parâmetros altura e diâmetro das mudas de beterraba aos 30 dias após a semeadura (DAS), onde o substrato Germinar ® acrescido de 7,5% de biochar apresentou melhor desempenho, com altura semelhante ao substrato Germinar Corroborando com os resultados encontrados, alguns estudos também demonstram ganho em altura (Mendonça et al, 2003;Souchie et al, 2011;Zanetti et al, 2003) e diâmetro (Souchie et al, 2011) Major et al, 2010;Steiner et al, 2007).…”

“…Contrariando esses resultados, Souchie et al (2011) discutem que a maior dose de biochar utilizada em mudas da árvore nativa carvoeiro (Tachigali vulgaris) foi eficiente para o desenvolvimento das mudas. Os autores observaram incrementos significativamente maiores em altura, diâmetro e biomassa aérea e radicular nos tratamentos com as maiores doses de biochar ao longo de oito meses, confirmando a eficácia do produto em médio prazo na produção de mudas.…”

“…Among the earliest studies are those made by Tryon (1948), Iswaran et al (1980) and Kishimoto & Sugira (1985). In the last decade the number of studies regarding the evaluation of the benefits of charcoal application to the soil for soil quality, plant biomass production and crop yields multiplied (e.g., Lehmann et al, 2003;Oguntunde et al, 2004, Major et al, 2005Madari et al, 2006;Steiner et al, 2007;Kimetu et al, 2008;Asai et al, 2009;Petter, 2010;Karhu et al, 2011;Laird et al, 2010;Zhang et al, 2011;Souchie et al, 2011). The beneficial physical and physical-chemical properties of biochar has been mentioned before.…”
