The inherent complexity of the concepts and equations governing surface fertigation has made this technique a challenging research issue in the past decades. A number of researchers have used field experiments and/or modelling results to develop recommendations aiming at improving surface fertigation management. In this paper, these recommendations are reviewed and classified considering the particular type of surface irrigation system. Key factors affecting surface fertigation performance, such as the inflow hydrograph, soil and water quality, effective root depth for fertilizer uptake and the specific surface irrigation method are discussed. The history of surface fertigation modelling is reviewed, introducing key developments, accomplishments and open issues. Finally, current research gaps and needs are identified and discussed, such as the coupling of two-dimensional surface and subsurface simulation models or the use of performance optimization approaches. Research gaps require an intensification of modelling and/or experimental efforts. 000062033 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000062033 590__ $$a0.703$$b2014 000062033 591__ $$aAGRICULTURE, MULTIDISCIPLINARY$$b25 / 56 = 0.446$$c2014$$dQ2$$eT2 000062033 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000062033 700__ $$aKeshavarz, M.R. 000062033 700__ $$aPlayán, E. 000062033 773__ $$g12, 3 (2014), 820-837$$pSpan. j. agric. res.$$tSPANISH JOURNAL OF AGRICULTURAL RESEARCH$$x1695-971X 000062033 8564_ $$s184040$$uhttps://zaguan.unizar.es/record/62033/files/texto_completo.pdf$$yVersión publicada 000062033 8564_ $$s117582$$uhttps://zaguan.unizar.es/record/62033/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000062033 909CO $$ooai:zaguan.unizar.es:62033$$particulos$$pdriver 000062033 951__ $$a2017-09-08-08:31:23 000062033 980__ $$aARTICLE
