Now-a-days, the recent technological adaptation in the field of agriculture is gradually increasing. Precision Agriculture presents the most innovative results emerging from research in the field of agriculture. This book aims to provide farmers with a wealth of information to build up a record of their farm, improve decision-making, foster greater traceability, enhance marketing of farm products, improve lease arrangements and relationship with landlords, enhance the inherent quality of farm products. Precision Agriculture technology (PA) is designed to provide information and data to assist farmers when making Site-Specific Management decisions. By making more informed management decisions, farmers can become more efficient, lower costs, and become more profitable. However, little is known about how farmers use PA to make management decisions, identify production problems, and about the relative magnitude of benefits and costs of PA on individual agricultural land. Presented method can be utilized for the monitoring and control of soil fertility using energy efficient Information and Communication Technology (ICT) and Wireless Sensor Network (WSN) environment.
