Precision agriculture in lime: potential for application of precision agriculture technologies in lime cropping systems.

In order to apply crop inputs on an as need basis, map and sensor-based precision agriculture (PA) technologies could be implemented in lime (Rutaceae) production for effective management of inputs to improve crop productivity. PA has several components, i.e. a differential global positioning system, a geographical information system, analysis of tree characteristics and field conditions, real-time measurement of soil properties, crop stress, pest pressure and disease using advanced sensors, control systems for automation of field operations, variable rate (VR) technology and yield monitoring systems. This chapter discusses PA technologies and their potential application in lime cropping systems to enhance productivity, reduce production cost and ensure environmental sustainability. It is concluded that spatial and temporal variations in soil properties, leaf nutrients and tree size in lime groves demand VR management of crop inputs to improve growth and productivity.
