Farmers can save water with wireless technologies, but there are challenges
- The Conversation
Water is the most essential resource for life, for both humans and the crops we consume. Around the world, agriculture accounts for 70% of all freshwater use.
In agriculture, it involves technologies such as wireless underground communications, subsurface sensing and antennas in soil. These systems help farmers track conditions on their land in real time, and apply water and other inputs such as fertilizer exactly when and where they are needed.
