However, seaweed biomass also offers a feedstock for the production of nutrient-rich biochar for soil amelioration. We provide the first data of biochar yield and characteristics from intensively cultivated seaweeds (<i>Saccharina</i>, <i>Undaria</i> and <i>Sargassum</i> – brown seaweeds<i>,</i> and <i>Gracilaria, Kappaphycus</i> and <i>Eucheuma</i> – red seaweeds). While there is some variability in biochar properties as a function of the origin of seaweed, there are several defining and consistent characteristics of seaweed biochar, in particular a relatively low C content and surface area but high yield, essential trace elements (N, P and K) and exchangeable cations (particularly K). The pH of seaweed biochar ranges from neutral (7) to alkaline (11), allowing for broad-spectrum applications in diverse soil types. We find that seaweed biochar is a unique material for soil amelioration that is consistently different to biochar derived from ligno-cellulosic feedstock. Blending of seaweed and ligno-cellulosic biochar could provide a soil ameliorant that combines a high fixed C content with a mineral-rich substrate to enhance crop productivity.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biochar from commercially cultivated seaweed for soil amelioration","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-24 01:31:25.853482","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2015-04-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000352468800001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/srep09665"},"refs":null,"anarec":{"AnaID":246197,"PubliDate":2015,"Pagination":"6 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5","Issue":"9665","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
