Precision farming relies on connected sensors to regularly communicate data on soil moisture, acidity/pH, temperature and nutrient levels, among other indicators. Precision farmers' goals for deployments are that devices are easy to install, simple to operate and do not rely on wires. Also, it's understood that solar power is ineffective because, as plants grow, their leaves obscure panels and dust and mud which are unavoidable in most types of farming have similar effects. 

LoRaWAN is a great fit, matching all of the above requirements. It is optimized for lower data rates and can transmit data over many kilometers. In addition, it is low power and because it relies on universal protocols, the costs of the connectivity can be shared across multiple devices. For example, LoRaWAN connectivity can be shared by soil sensors, agricultural machines, and other applications.
