Tule Technologies

Tule Technologies is a Davis, California-based agricultural technology company that has developed a unique approach to precision irrigation: measuring actual crop water use directly from plant canopy sensors rather than relying solely on weather-based evapotranspiration models. The company's proprietary sensor technology measures vapor pressure above plant canopies to calculate actual crop ET (evapotranspiration) in real time.\n\nThis plant-based sensing approach allows growers to see exactly how much water their crops are consuming under current field conditions — accounting for the complex interactions of microclimate, soil variability, and crop development stage that weather-station models often miss. The platform delivers this data through a simple dashboard with irrigation recommendations, helping growers in water-stressed regions like California's Central Valley optimize every acre-inch of applied water.\n\nTule serves growers of high-value crops including almonds, pistachios, wine grapes, and processing tomatoes, where precise water management has both significant economic and regulatory implications. As California's water regulations tighten, Tule's ability to provide defensible, crop-specific water use data positions it as a critical compliance and optimization tool for irrigated agriculture.
