Resumo: This work aimed to analyze the decomposition and nutrient content of the litterfall in a crop-livestock-forestry integrated system (CLFI) located in Embrapa Cerrados, Planaltina, Distrito Federal, Brazil. Litter traps were distributed and litterbags were used to investigate the decomposition. The litter traps and litterbags were allocated between the tress and ranks. Each litterbag was filled with 20 g of eucalyptus litterfall. The samples of both collections were sent to a laboratory to determine the macronutrient content. The total litterfall was 9,394.2 kg ha-1 between the tress and 3,726.4 kg ha-1 between ranks. The precipitation showed a high influence on the litterfall decomposition. The decomposition rates were similar to both positions and the half-life time in the short and long period (recalcitrant) were respectively 10 and 1,386 days between tress and 10 and 1,155 between ranks. The litterfall nutrient content (N, P, K, S, Ca and Mg) was high between trees. Ca and N showed greater content during the deposition and decomposition process independent of the position in the CLFI.

Foram instalados coletores de serapilheira, e foram utilizados litterbags para avaliação da decomposição. Os coletores e os litterbags foram alocados entre árvores e entre renques. Em cada litterbag foram adicionados 20 g de serapilheira de eucalipto. As amostras de serapilheira de deposição e da decomposição foram secas e encaminhadas para laboratório, para análise de macronutrientes. A produção total de serapilheira foi de 9.394,2 kg ha-1 entre árvores e 3.726,4 kg ha-1 entre renques. A precipitação pluvial influenciou marcadamente a decomposição da serapilheira foliar. As taxas de decomposição foram similares para ambas posições, e o tempo de meia vida da decomposição em curto período e recalcitrante foram, respectivamente, de 10 e 1.386 dias entre árvores e de 10 e 1.155 dias entre renques. Os conteúdos de nutrientes (N, P, K, S, Ca e Mg) da serapilheira foram superiores na posição entre árvores. Desses, o Ca e o N foram os que apresentaram maiores conteúdos no processo de deposição e decomposição, independentemente da posição.Embrapa Florestas2022-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/207210.4336/2022.pfb.42e201902072Pesquisa Florestal Brasileira; v. 42 (2022)Pesquisa Florestal Brasileira; Vol. 42 (2022)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2072/1659https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessRibeiro, Fabiana PiontekowskiPulrolnik, KarinaVilela, LourivalGatto, Alcides2022-12-14T14:46:53Zoai:pfb.cnpf.embrapa.br/pfb:article/2072Revistahttps://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:2022-12-14T14:46:53Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
