Highest (246.6 52.7 g m 2) and lowest (123.2 89.5 g m 2) peak biomass occurred in 2006 and 2005 respectively. Total soilNwithin the top 20 cmsoil profile ranged between 0.2 0.1% in February and 0.41 0.2% inMay,while available soil N was lowest (5 2 mg g 1soil) in February but increased three-to-five fold in March and was >17.5 mg g 1soil at senescence in May. Significant (p < 0.001) increase in total N in the aboveground pool occurred between February and May. There was however, no decay in soil N content. Instead, the herbaceous vegetation enhanced soil N input and N retention in the ecosystem. Most of the herbaceous plants were annuals with large reserves of organic N at senescence, which returned to the soil as detritus. The herbaceous vegetation is a critical component of the montado that contributes to N recharge and cycling within the ecosystemElsevierRepositório da Universidade de LisboaOtieno, D.O.Mirzaei, H.Hussain, M.Z.Li, Y.L.Schmidt, M.W.T.Wartinger, M.Jung, E.Ribeiro, N.Pereira, J.S.Tenhunen, J.2012-04-24T14:17:44Z20112011-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.5/4273eng"Journal of Arid Environments".
