| contents | Corn (Zea mays L.) is one of the most sensitive cereal crops in the world and in order to achieve high level of productivity, it is more reliant on the input of nitrogen (N). Conventional ways of applying uniformly the fertilizers lack consideration of the spatial and time variations and hence loss of nitrogen and the environment. Site-specific management of nutrients is made possible by precision agriculture technologies such as variable rate application (VRA), sensor-based nutrient monitoring, unmanned aerial vehicles (UAVs), and GPS/GIS-guided systems. This is a review of recent research on precision fertilizer technologies in production of corn. Results of various studies show that using precision methods can decrease nitrogen inputs by about 15-30% and still retain the same or even higher yields and nitrogen use efficiency (NUE). However, the adoption remains low because of high initial expenses, technicalities, and the lack of long-term validation. The cost-effective technologies and integrated decision support systems should be the subject of future research. |
