Abstract
Abstract. Real time knowledge of soil moisture is helpful to assure quality crop yields and reduce the negative offsite effects of irrigation. Manual data retrieval from each field is time consuming and wiring complicates cultural practices. The combined use of soil moisture sensors, a wireless sensor web, and internet communication could allow growers to view soil moisture data, sensor diagnostics, and other useful information from a computer, smartphone, or tablet. We tested an IRROmeshTM system that used a SensMit WebTM smartmesh radio platform. The system read soil temperature and soil water tension using three WatermarkTM soil moisture sensors in each of twelve fields planted to eight different crops. Real time soil data and graphs of soil water tension trends were easily accessible by smart phone. These preliminary trials using the sensor web showed that this technology holds potential for saving time, increasing accuracy of irrigation scheduling, and assuring yield.
