2. Introduction • Humanity depends on agriculture and water for survival, so efficient, profitable and sustainable use of our land and water resources is critical. • This paper proposes the agricultural management system (AMS), which can be automated by the efficient usage or deployment of wireless sensor network (WSN) on-field. • The agricultural management system (AMS) incorporated cheap and simple devices that learn about their environment and seek control for beneficial purposes such as soil temperature, soil moistures and animal tailgating.

4. WSN for monitoring soil moisture and temperature • Soil moisture nodes use commercially available ECH2O capacitance-based sensors that measure the surrounding soil’s volumetric water content. • The network automatically takes readings, typically at one-minute intervals, from each node and sends them back. 3. By knowing the soil moisture level of the pasture, the drip irrigation system which has been already implemented can be controlled through the WSN network by controlling the valve’s of the drip irrigation system.

6. Contd… • The soil moisture and valves are directly controlled by the proposed system in a controlled manner the scarcity of the water can be reduced. Figure 2 : ECH2O Volumetric water sensor SVCE,BANGALORE

7. 2. Cattle Sensor Networks • By knowing the placement and grazing habit of the cattle’s the farmers will get the alarm stating that cattle’s are feeding on the crop and so the farmer can be alerted to divert the cattle’s far from the agricultural crops. • This system includes a sensory collar attached to the cattle’s and sheep’s. Likewise the animal tailgating into the agricultural areas can be avoided so that the damage which can occur by the animals can be minimized. • By implementing this system we can minimize the damage done by animals as well as we can minimize the labor requirement.

9. 3. UAV’s for Agricultural applications • A UAV is used to spray chemicals on an agricultural field. • If the UAV used for spraying comes too close to the neighboring field, or if there is a sudden change in the direction of the wind, the chemicals might fall on the neighboring field and this must be avoided. • To be able to adjust the trajectory, we propose that the UAV gets information from the WSN deployed in the crop field. Whether a sensor detects an excessive concentration of chemicals, the spraying UAV will be directed away from the border. SVCE,BANGALORE

11. Closing Remarks • Although, the wireless farm of the future offers great potential for improving efficiencies, it will not materialize without the support of farmer’s ability to understand the electronics devices • the most robust wireless system will require regular maintenance, repair and upgrades. In this paper we have described how an AMS can be implemented based on WSN. • As a future work, we propose large scale deployment to observe the impact on the role of node in handling numerous queries from the in-field sensor nodes.
