In this chapter, it has been highlighted that spatial variability exists in the soil properties and crop parameters. Fertilizers, when applied uniformly in the fields without considering the variability, result in wastage of inputs and environmental degradation. Precision agriculture (PA), involving various technologies such as Remote Sensing, Geographical Information system (GIS), and Global Positioning System (GPS), helps in managing the inputs precisely based on soil and crop need. PA estimates the variability present in the crop and field with the help of different techniques and advanced sensors and then employs the results to efficiently fulfill crop needs. This technique helps to enhance the quality of the crop and yield and lower the environmental risk by implementing irrigation water, pesticides, and fertilizers on a needed base, leading to sustainable agriculture.
