Sensors key to advances in precision agriculture

Abstract

Purpose

This study aims to illustrate the growing role that sensors play in agriculture, with an emphasis on precision agricultural practices.

Design/methodology/approach

Following a short introduction, this study first provides an overview of agricultural measurements and applications. It then discusses the importance of airborne and land-based optical sensing techniques and the role of the normalised difference vegetation index. Sensors used on conventional and robotic agricultural machines are considered next, and fixed sensors and sensor networks are then discussed. Finally, brief concluding comments are drawn.

Findings

This shows that much modern agriculture is a high-technology business which relies on a multitude of sensor-based measurements. Sensors are based on a diversity of optical and other technologies and measure a wide range of physical and chemical variables. They are deployed in the air, on agricultural machines and in the field and generate data that can be used to enhance productivity and reduce both costs and the impact on the environment.

Originality/value

This provides a detailed insight into the important role played by sensors in modern agricultural practices.
