“…The first strategy uses the soil advection-dispersion equation. One-and twodimensional forms of this equation have been used for border/basin and furrow irrigation, respectively (Zerihun et al, 2005a;Ebrahimian et al, 2013a). The twodimensional approach is used to represent the soil underneath a cross-sectional furrow section.…”

Surface fertigation is a common choice when it comes to applying fertilizers in surface irrigated crops. 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.Additional key words: fertilizers; inflow hydrograph; modelling; soil and water quality; effective root depth.

“…The HYDRUS (2D/3D) model and its predecessors, such as SWMS-2D and HYDRUS-2D, have been widely used in the past to simulate water flow and/or solute transport for furrow irrigation systems (e.g., Benjamin et al 1994;Abbasi et al 2003aAbbasi et al , b, 2004Rocha et al 2006;Wöhling et al 2004aWöhling et al , b, 2006Mailhol et al 2007;Warrick et al 2007;Wöhling and Schmitz 2007;Wöhling and Mailhol 2007;Crevoisier et al 2008;Lazarovitch et al 2009;Ebrahimian et al 2012Ebrahimian et al , 2013aZerihun et al 2014).

The effect of different fertigation strategies and furrow surface treatments on plant water and nitrogen use

scenarios with plastic and irrigation in alternate furrows showed a reduction in transpiration and yield, more water loss due to deep drainage, and less water lost due to evaporation. However, similar crop yields were obtained for this alternate furrow strategy as for the control furrow surface treatments. When only half the water was used for irrigation in this scenario, the reduction in yield was less than 20 % compared to the control treatments, producing higher water-use efficiency.

“…For example, shallow wetting irrigation and shallow irrigation combined with timely fi eld drying has shown that the paddy fi eld had more suffi cient sunlight than that in fl ooding irrigation, which could increase fi nal rice yield [7][8][9]. Alternate furrow irrigation, applying water to one of two continuous furrows, has been applied mainly in arid and semi-arid regions to conserve water and to increase water productivity in agricultural lands [10][11][12]. Drip irrigation can reduce the irrigation amount without reduction in crop yield and hence increase water use effi ciency by delivering water directly to the roots of the crop and reducing evapotranspiration and percolation.…”

Rice is a widely cultivated crop in China and needs a large quantity of water during its entire growth period. Many water-saving irrigation techniques have been developed and widely applied to conserve water in paddy fi elds in recent years. A controlled and mid-gathering irrigation (CMI) regime is one of them, of which the main feature is to maximize the use of rainwater different from the others. The objective of this study was to assess and verify the water conservation and nitrogen pollution reduction effects of CMI in comparison with a conventional irrigation (CVI) regime. Results showed that the CMI method had potential for water conservation by reducing total irrigation amount and irrigation frequency and making better utilization of rainwater during the rice growth stage. By making use of irrigation water more effi ciently, CMI showed higher irrigation water use effi ciency and rainfall use effi ciency. CMI can also reduce nitrogen pollution emitted to the water system by reducing the pollutant discharge rather than the pollutant concentration during a storm event. However, the irrigation regime's effect on pollutant loading reduction was not as signifi cant as fertilizer according to experiment results. Thus, the controlled and mid-gathering irrigation regime was favorable for water conservation and reducing emissions of non-point source pollution.
