Resumo: | Caatinga is one of the Brazilian biomes where the highest degradation rates are recorded. It is associated mainly to the removal of vegetation for energy production and practice of subsistence agriculture, causing interference in nutrient cycling. The aim of the study was to quantify and chemically analyze litter deposition in a fragment of Caatinga, located in the municipality of Pombal, Paraíba (PB) state. It was collected monthly for 12 months, and separated into different fractions (leaves, reproductive structures, branches and miscellaneous), all litter deposited on collectors of 1.0 m2, distributed systematically. The nutrients analyzed were N, P, K, Ca and Mg. The annual litter was of 3785.67 kg ha-1, predominantly composed of leaf fraction with 70.2%, followed by the fraction reproductive structures with 18.3%. The nutrient content in the leaf litter followed the order Ca> N> K> Mg> P. The nutrient content in the fractions vary according to time and there is evidence of their relationship with the rainfall. The deposition of litter coincided with the seasonal period of Caatinga. |

O objetivo do trabalho foi quantificar e analisar quimicamente a deposição de serapilheira em um fragmento de Caatinga, localizado no município de Pombal - PB. Foi coletada mensalmente, durante 12 meses, e separada em diferentes frações (folhas, estruturas reprodutivas, galhos e miscelânea) toda serapilheira depositada em coletores de 1,0 m2 de área, distribuídas de forma sistemática. Os nutrientes analisados foram N, P, K, Ca e Mg. A deposição anual de serapilheira foi de 3.785,67 kg ha-1, composta predominantemente da fração folha com 70,2%, seguida pela fração estruturas reprodutivas com 18,3%. Os teores de nutrientes na serapilheira seguiram a ordem Ca>N>K>Mg>P. O teor de nutrientes nas frações varia em função do tempo e há evidências de sua relação com a precipitação pluviométrica. A deposição da serapilheira coincidiu com o período de sazonalidade da Caatinga.Universidade Federal de Santa Maria2017-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2774710.5902/1980509827747Ciência Florestal; Vol. 27 No. 2 (2017); 621-633Ciência Florestal; v. 27 n. 2 (2017); 621-6331980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/27747/pdf_1Copyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessde Holanda, Alan CauêFeliciano, Ana Lícia PatriotaFreire, Fernando Joséde Sousa, Flaubert QueirogaFreire, Saul Ramos de OliveiraAlves, Allyson Rocha2017-07-25T01:25:05Zoai:ojs.pkp.sfu.ca:article/27747Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-07-25T01:25:05Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
