A Review on Precision Agriculture and Its Farming Methods

In recent times, the major characteristics of wireless technology like communication and sensing are real time basis and it provides better response time and low power requirements. Both features have been established and totally determined with precision agriculture. Wireless sensor networks are considered as developing technology for proficient and economical Precision Agriculture (PA). Prior to precision agriculture the farmers depend on many technologies like satellite and aircraft imagery based systems to exactly focus their growing areas, but PA technology provide the real time feed-back on a spot variables, crop conditions. By using WSN, size of the crop area is analysed as well it gives report based on amount of fertilizer and water which are sufficient for the crop. Precision agriculture comprises of monitoring soil, crop climate condition, and takes various actions which are based on real time modification of fertilizer or pesticide application. Some of the important techniques such as digging the land and plotting the seeds in, watering the crops, harvesting and storage etc. In WSN several issues are included such as connectivity and coverage and also nodes deployment, control algorithm and architecture are the main challenges.
