Proposed soil sensor network to enable precision and sustainable agriculture.

The nutrient needs of crops depend heavily on the soil properties (moisture, temperature, nutrients and SOM), climactic conditions and historical crop management data. Innovations are required in reliable, robust and affordable sensing of the soil properties and the understanding of Crop Growth versus N-Cycling. Researchers from Iowa State are addressing these through the development of a network of in-situ, wireless soil moisture and nutrient sensors capable of self-calibrating, self-localizing and energy-conserving/energy-harvesting.
