Resumo: From the perspective of the "forms of humus", the litter is an indicator of the integrity of forest ecosystems: the organic material arranged in internal layers, varying in weight and thickness, expresses the cycle of nutrients that synthesizes the functioning of ecosystems. Thus, this research seeks to study which nutrients are released by the action of rain, leaching the organic material present in the treetop and in the soil, as well as that in the inner layers of the litter in an urban forest of tropical climate. For this purpose, experimental rain gauges were built to collect the rain and deposit it in containers below each layer of litter for chemical analysis. As a result, we realized that, when this process happens with humus mull-moder forms, the different layers will nourish the soil in a different way, for example, calcium is released in greater quantity by layers F and MFB; potassium and magnesium are more available through the L layer, indicating that during this process these nutrients are consumed more than released. And finally, sodium is abundant in the rains before it reaches the litter.

Así, esta investigación pretende estudiar cuáles son los nutrientes liberados por la lluvia, lixiviando el material orgánico presente en la copa de los árboles y en el suelo, así como también el encontrado en las diferentes capas internas de hojas esparcidas en una zona forestal urbana de clima tropical. Fueron construidos pluviómetros experimentales para colectar la lluvia, depositándola en recipientes colocados debajo de cada capa de hojas para, posteriormente, pasar por un análisis químico. Como resultado percibimos que, cuando ese proceso se da en formas de humus mull-moder, las diferentes capas nutrirán el suelo de manera diferenciada; por ejemplo, el calcio es liberado en mayor cantidad por las capas F y MFB; por otro lado, el potasio y el magnesio aparecen mayoritariamente en la capa L, indicando que durante el proceso estos nutrientes son más consumidos que liberados. Y, finalmente, el sodio es abundante en las lluvias ante de llegar a las capas de hojas dispersas en el suelo forestal.A serapilheira é indicadora da integridade de ecossistemas florestais quando analisamos sob a perspectiva das “Formas de Humus”. Sendo o material orgânico disposto em camadas internas que variam no peso e espessura e expressa a ciclagem de nutrientes, que sintetiza o funcionamento dos ecossistemas. A pesquisa propõe entender que nutrientes são liberados pela ação da chuva lixiviando o material orgânico na copa e no solo, bem como pelas camadas internas da serapilheira numa floresta urbana de clima tropical. Foram construídos pluviômetros experimentais que coletavam a chuva e a depositava em recipientes abaixo de cada camada de serapilheira para análise química. Como resultados, percebemos que as diferentes camadas vão nutrir o solo de maneira diferenciada quando esse processo acontece com formas de humus mull-moder. O cálcio  é liberado em maior quantidade pelas camadas F e MFB, o potássio e o magnésio têm maior disponibilização pela camada L, indicando que durante esse processo esses nutrientes são mais consumidos do que liberados. O sódio é abundante nas chuvas antes de atingir a serapilheira.Universidade Estadual de Londrina2020-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/3917910.5433/2447-1747.2020v29n2p205GEOGRAFIA (Londrina); v. 29 n. 2 (2020); 205 - 2182447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELporhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/39179/27604Copyright (c) 2020 GEOGRAFIA (Londrina)http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessD´Arrochella, Marcio Luiz Gonçalves2022-09-20T15:44:09Zoai:ojs.pkp.sfu.ca:article/39179Revistahttps://www.uel.br/revistas/uel/index.php/geografiaPUBhttps://www.uel.br/revistas/uel/index.php/geografia/oairevista.geografia.uel@gmail.com||marcar@uel.br||laudi@uel.br2447-17470102-3888opendoar:2022-09-20T15:44:09Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
