Ciclagem de nutrientes em dois trechos de floresta estacional semidecidual na reserva florestal mata do paraíso em Viçosa, MG, Brasil

Abstract: Dois trechos de Floresta Estacional Semidecodual, em distintos estádios sucessionais (inicial e maduro), da região de Viçosa, MG, foram estudados com o objetivo de quantificar a produção anual e o conteúdo de N, P, K, Ca e Mg da serapilheira, bem como caracterizar a dinâmica de decomposição e liberação dos nutrientes desse compartimento e a eficiência anual de utilização dos nutrientes. A queda anual de serapilheira foi de 6.310 kg.ha-1 no trecho de floresta em seu estádio inicial e de 8.819 kg.ha-1 no de flor… Show more

“…Some authors have reported this same trend in tropical forests, such as Menezes et al (2010) who studied the contribution of litterfall in three distinct characteristics of secondary forests in the Atlantic domain, near the region of Rio de Janeiro and found annual litterfall production ranging from 6,584 to 10,097 kg ha -1 year -1 . Pinto et al (2009) studied the litterfall in two forests with distinct successional features and found a greater production of deciduous material at the end of the dry season and beginning of the rainy season, being the disturbed place the site with the highest value of litterfall production. Pimenta et al (2011) studied nutrient cycling in a semideciduous forest in southern Brazil and found a greater production of litterfall at the onset of the rainy season.…”

“…In a primary Atlantic forest, Souza Neto et al (2011) evaluated the litterfall along an altitudinal gradient in the region of Ubatuba, northern region of the São Paulo State and found values of 5.5; 7.4 and 8.4 Mg ha -1 year -1 for altitudes of 100, 400 and 1000 meters, respectively. It is important to highlight that in a disturbed area with high concentration of atmospheric pollution near São Paulo city, Domingos et al (1997) found values of high litterfall production in September (847 kg ha -1 ) and lowest in July (337 kg ha -1 ), with total production estimated of 7007 kg ha -1 year -1 .…”

“…O teor de matéria orgânica que se elevou na análise realizada em 2012 é devido, principalmente, à decomposição da serapilheira, que constitui o principal meio de transferência de matéria orgânica e elementos minerais da vegetação para o solo (VITAL et al, 2004;PINTO et al, 2009).…”
