NERC Environmental Information Data Centre. https://doi.org/10.5285/c2eaade3-5395-4c62-9733-d9dbed1546af" ; dcterms:description "The data consists of leaf nutrients from litterfall in a fertilised old-growth forest in the Central Amazon. Data was collected in a full factorial nutrient addition experiment (nitrogen, phosphorus, and cation treatments). The dataset includes realized nutrient concentration carbon, nitrogen, phosphorus, potassium, magnesium, calcium in grams and manganese, zinc in miligrams. Also hemicellulose, cellulose and lignin as a percentage. The fieldwork was completed in August of 2017, 2018, and 2019. The study was funded by NERC, BDFFP (logistical support), and the Brazilian government (students scholarship)." ; dcterms:provenance [ a dcterms:ProvenanceStatement ; rdfs:label "To determine macro and micronutrients and secondary compounds, litter samples were bulked by plot using litterfall material collected during the months of August of 2017, 2018, and 2019. 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). Concentrations 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." ] ; dcterms:spatial [ a dcterms:Location ; dcat:bbox "POLYGON((-60 -2.5, -60 -2, -59 -2, -59 -2.5, -60 -2.5))"^^geo:wktLiteral ; ] ; dcterms:temporal [ a dcterms:PeriodOfTime ; dcat:startDate "2017-08-01"^^xsd:date ; dcat:endDate "2019-08-01"^^xsd:date ; ] ; dcat:contactPoint ; dcterms:publisher ; dcterms:isPartOf ; dcterms:subject "Brazil", "Central Amazon", ; a dcat:Dataset; dcterms:type dcmitype:Dataset ; dcterms:available "2021-03-30"^^xsd:date ; dcat:landingPage , ; dcterms:license ; dcterms:rights [ a dcterms:RightsStatement ; odrs:copyrightNotice "copyright Natural Environment Research Council"; ] ; dcterms:accessRights ; dcterms:theme ; dcat:distribution [ dcat:accessURL ; dcterms:license ; dcterms:rights [ a dcterms:RightsStatement ; odrs:copyrightNotice "copyright Natural Environment Research Council"; ] ; dcterms:accessRights ; dcterms:format [ a dcterms:IMT ; rdf:value "Comma-separated values (CSV)" ; rdfs:label "Comma-separated values (CSV)" ] ; ]; dcterms:creator , :c2eaade3-5395-4c62-9733-d9dbed1546af_a1, :c2eaade3-5395-4c62-9733-d9dbed1546af_a2, , :c2eaade3-5395-4c62-9733-d9dbed1546af_a4, ; dcterms:language . a foaf:Person ; foaf:name "Moraes, A.C.M." ; foaf:familyName "Moraes" ; foaf:givenName "A.C.M." ; vcard:hasEmail "annacmmoraes@gmail.com" ; foaf:member [foaf:name "National Institute of Amazonian Researches"] ; . a foaf:Organization ; foaf:name "NERC Environmental Information Data Centre" ; vcard:hasEmail "info@eidc.ac.uk" ; foaf:member ; . a foaf:Person ; foaf:name "Moraes, A.C.M." ; foaf:familyName "Moraes" ; foaf:givenName "A.C.M." ; vcard:hasEmail "annacmmoraes@gmail.com" ; foaf:member [foaf:name "National Institute of Amazonian Researches"] ; . :c2eaade3-5395-4c62-9733-d9dbed1546af_a1 a foaf:Person ; foaf:name "Martins, M.P." ; foaf:familyName "Martins" ; foaf:givenName "M.P." ; vcard:hasEmail "meyre_ripardo@hotmail.com" ; foaf:member [foaf:name "National Institute of Amazonian Researches"] ; . :c2eaade3-5395-4c62-9733-d9dbed1546af_a2 a foaf:Person ; foaf:name "Siebert, L." ; foaf:familyName "Siebert" ; foaf:givenName "L." ; vcard:hasEmail "larasiebert94@gmail.com" ; foaf:member [foaf:name "National Institute of Amazonia Researches"] ; . a foaf:Person ; foaf:name "Andersen, K.M." ; foaf:familyName "Andersen" ; foaf:givenName "K.M." ; vcard:hasEmail "kelly.andersen@ntu.edu.sg" ; foaf:member [foaf:name "National Institute of Amazonia Researches"] ; . :c2eaade3-5395-4c62-9733-d9dbed1546af_a4 a foaf:Person ; foaf:name "Quesada, C.A.N." ; foaf:familyName "Quesada" ; foaf:givenName "C.A.N." ; vcard:hasEmail "quesada.beto@gmail.com" ; foaf:member [foaf:name "National Institute of Amazonia Researches"] ; . a foaf:Person ; foaf:name "Hartley, I.P." ; foaf:familyName "Hartley" ; foaf:givenName "I.P." ; vcard:hasEmail "i.hartley@exeter.ac.uk" ; foaf:member [foaf:name "National Institute of Amazonian Researches"] ; . a skos:Concept; skos:prefLabel "Environmental Survey"; rdfs:label "Environmental Survey" .
