Resumo: This study aimed to quantify nutrient content in shoot biomass components and litter in two areas of savanna vegetation with different ecological characteristics, one in regeneration and the other as a preserved area, in Floresta, Pernambuco State, Brazil. It was carried out an initial inventory launching 40 plots of 400 m2 in each area, with inclusion level of circumference at 1.3 m above ground level ≥ 6.0 cm. The five species with highest importance value were used for biomass analysis. Chemical analysis were carried out in samples of 100 g taken from the different component of each of those species. To estimate the stock of litter assortments were made in dry and rainy seasons, using a hollow square mold with 0.5 m randomly released in plots. It was observed that the nutrient content found in total biomass in both areas followed the same sequence: N > Ca > K > Mg > P > S. Litter stock from the preserved area were higher in all fractions, however differences were observed between seasons. In the dry season the sequence was: N > Ca > S > K > Mg > P, and in the rainy season N > Ca > K > S > P > Mg in both areas. When the nutrient content was available, the litter presented the highest nutrient contents compared to those present in the biomass above the soil.

Foi realizado inventário inicial lançando-se 40 parcelas de 400 m2 em cada área, tendo como nível a inclusão de circunferência a 1.30 m do solo ≥ 6,0 cm. Para análise da biomassa, foram utilizadas as cinco espécies de maior valor de importância de cada área. De cada um delas, foram retiradas amostras com 100 g para realização das análises químicas de seus componentes. Para a estimativa do estoque de serapilheira, foram feitas coletas no período seco e chuvoso, utilizando-se um molde quadrado vazado de 0,5 m, lançado aleatoriamente nas parcelas. Observou-se que o teor de nutrientes encontrados na biomassa total nas duas áreas seguiu uma mesma sequência: N > Ca > K > Mg > P > S. A área preservada apresentou maior acúmulo em todas frações no estoque de serrapilheira, mas com diferenças entre as estações. No período seco a sequência foi: N > Ca > S > K > Mg > P, e no chuvoso N > Ca > K > S > P > Mg em ambas as áreas. Quando os nutrientes estavam disponíveis, a serapilheira apresentou os maiores conteúdos de nutrientes, quando comparada com os estoques presentes na biomassa acima do solo.Embrapa Florestas2017-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/106010.4336/2017.pfb.37.92.1060Pesquisa Florestal Brasileira; v. 37 n. 92 (2017): out./dez.; 413-420Pesquisa Florestal Brasileira; Vol. 37 No. 92 (2017): out./dez.; 413-4201983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1060/598Alves, Allyson RochaFerreira, Rinaldo Luiz Caracioloda Silva, José Antônio AleixoDubeux Júnior, José Carlos BatistaSalami, Gabrielainfo:eu-repo/semantics/openAccess2019-01-02T18:39:22Zoai:pfb.cnpf.embrapa.br/pfb:article/1060Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2019-01-02T18:39:22Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
