Satellite imaging

It is also known as remote sensing where the crops can be monitored through satellites. The information about the fields is gathered by scanning the fields with a high-​flying flight or by satellites. It collects data about the crop conditions and soil to manage the crop properly as an optimal irrigation system (Sheffield and Morse-​Mcnabb, 2014; Khirade & Patil, 2015; Zhang et al., 2016). The limitation of this farming is that it is very costly.
