Sand from various locations on the dunes and foreshore is analysed for total nitrogen and readily available nitrogen. Ranking sand in order of increasing readily available nitrogen gives the following; main dune sand < foredune sand < freshly blown sand < foreshore sand. A survey of foreshore sand from sites on the east coast of Ireland and Connemara shows that, at most sites a relatively large proportion of total nitrogen is readily mineralized. The N requirement of marram on an actively growing dune is found to be met adequately by mineralization of organic N contained in dune sand. Asymbiotic nitrogen fixation is estimated to be insignificant in the N economy of marram in young dunes. An experiment on the growth response of <i>Ammophila</i> and <i>Elymus</i> to the surface application of fresh windblown sand and nitrogen showed that the response of <i>Ammophila</i> to both treatments was identical and significantly greater than the control. <i>Elymus</i> responds positively to nitrogen but there is no difference between control and sand treatment. It is concluded that the response of <i>Ammophila</i> to burial by sand may be a response to nitrogen released from the sand. The foreshore is seen as a reservoir of available N that is carried to the dunes with windblown sand.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"The foreshore as a nitrogen source for marram grass","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1992,"MonPub":null,"DateUpdate":"2020-04-27","DateCreate":"2001-07-03","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":12643,"PubliDate":1992,"Pagination":"177-188","XtraPublOfAnaID":null,"ISBN":"90-5410-058-3","Volume":null,"Issue":null,"BRefMon":12581,"BRefMonRR":"<b>Carter, R.W.G.; Curtis, T.G.F.; Sheehy-Skeffington, M.J.
