All analysis were conducted at INPA's soil and plants lab. After dried, samples 0.5g of each sample were ground using a knife and/ or ball mill for nutritional analysis. Leaves and insect frass were analysed separately. Micronutrients, phosphorus, and cations were analysed by nitroperchloric digestion protocol described by Malavolta et al. (1989). The base cations (K, Ca, and Mg) and micronutrients were determined by atomic absorption spectrophotometry (AAS, 1100 B, Perkin-Elmer, Ueberlingen, Germany) (Anderson and Ingram, 1993). The total P concentrations were determined by colorimetry (Anderson and Ingram, 1993), and quantified by spectrophotometry (UV-120-01, Shimadzu, Kyoto, Japan). The C and N contents were determined using an automatic C and N analyzer (VARIO MAX CHN Element Analyzer) (Nelson and Sommers, 1996). Leaves were not identified by species and leaf characteristics represent means at plot level (Metcalfe et al., 2014). \n\nConcentrations of lignin and cellulose in the litter were determined by the ADF- sulfuric method (Van Soest, 1963; Rowland and Roberts, 1994). The method consists in applying an acidic detergent solution (ADF), followed by the cellulose using H2SO4 72%, with lignin subsequently determined by weight loss on ignition 0 to 50° C in a muffle furnace. \n","metadataDate":"2026-06-27T18:14:05","notGEMINI":true,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/c2eaade3-5395-4c62-9733-d9dbed1546af","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/c2eaade3-5395-4c62-9733-d9dbed1546af.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"familyName":"Moraes","givenName":"A.C.M.","organisationName":"National Institute of Amazonian Researches","role":"pointOfContact","email":"annacmmoraes@gmail.com","nameIdentifier":"https://orcid.org/0000-0002-2541-5320","fullName":"Moraes, A.C.M.","pointOfContact":"National Institute of Amazonian Researches"}],"publicationDate":"2021-03-30T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"relationships":[{"relation":"http://purl.org/dc/terms/isPartOf","target":"79c9df71-af3b-4ca8-8df8-330fc5fc3507"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/c2eaade3-5395-4c62-9733-d9dbed1546af"},{"code":"10.5285/c2eaade3-5395-4c62-9733-d9dbed1546af","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Moraes","givenName":"A.C.M.","organisationName":"National Institute of Amazonian Researches","role":"author","email":"annacmmoraes@gmail.com","nameIdentifier":"https://orcid.org/0000-0002-2541-5320","fullName":"Moraes, A.C.M."},{"familyName":"Martins","givenName":"M.P.","organisationName":"National Institute of Amazonian Researches","role":"author","email":"meyre_ripardo@hotmail.com","fullName":"Martins, M.P."},{"familyName":"Siebert","givenName":"L.","organisationName":"National Institute of Amazonia Researches","role":"author","email":"larasiebert94@gmail.com","fullName":"Siebert, L."},{"familyName":"Andersen","givenName":"K.M.","organisationName":"National Institute of Amazonia Researches","role":"author","email":"kelly.andersen@ntu.edu.sg","nameIdentifier":"https://orcid.org/0000-0002-1460-9904","fullName":"Andersen, K.M."},{"familyName":"Quesada","givenName":"C.A.N.","organisationName":"National Institute of Amazonia Researches","role":"author","email":"quesada.beto@gmail.com","fullName":"Quesada, C.A.N."},{"familyName":"Hartley","givenName":"I.P.","organisationName":"National Institute of Amazonian Researches","role":"author","email":"i.hartley@exeter.ac.uk","nameIdentifier":"https://orcid.org/0000-0002-9183-6617","fullName":"Hartley, I.P."},{"familyName":"Moraes","givenName":"A.C.M.","organisationName":"National Institute of Amazonian Researches","role":"pointOfContact","email":"annacmmoraes@gmail.com","nameIdentifier":"https://orcid.org/0000-0002-2541-5320","fullName":"Moraes, A.C.M.","pointOfContact":"National Institute of Amazonian Researches"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["textTable"],"spatialResolutions":[{"distance":"1000","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2017-08-01","end":"2019-08-01"}],"title":"Litterfall nutrient content in fertilised plots in the Central Amazon, 2017-2019","topicCategories":[{"value":"biota","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/biota"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/7"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/c2eaade3-5395-4c62-9733-d9dbed1546af","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"},{"value":" © Natural Environment Research Council","code":"copyright"}]}
