Water scarcity, as well as the over application of fertilizers, are big challenges for sustainable agricultural development in the North China Plain (NCP). As surface irrigation and broadcast fertilisation are widely used but poorly managed by smallholder farmers in NCP, so it is needed to improve the on-farm irrigation and fertilisation practices by modifying the existing system. Then surface fertigation seems to be the most feasible method to improve the current situation. Studies on surface fertigation have been performed since the late 1980s, although farmers had used it for a long time. Research that can address farmers’ challenges about water and fertiliser conservation are still required, as well as the sustainability of surface fertigation systems. This research aims to develop the optimised practices of on-farm surface fertigation that based on farmers’ acceptance, improving the water and fertiliser use efficiency and decreasing the impact of nitrogen leaching on the agro-ecology system.
