California’s water challenges require smart irrigation

In California, every drop of water counts. Ongoing droughts, strict water regulations, and rising production costs push farmers to find smarter, data-driven ways to manage irrigation. Soil moisture sensors give growers real-time insight into what’s happening beneath the surface, helping them decide exactly when and how much to irrigate.

By using accurate soil data instead of guesswork, California farmers can improve crop yields, reduce water waste by up to 30%, and make their operations more sustainable in the face of a changing climate.

Used in 3,000+ fields across the U.S.

According to California Department of Water Resources precision irrigation plays a critical role in achieving sustainable water use across the state.

100% maintenance free

No wires, no fuss

Highly secure data connection

Suitable for all soil types

Real-time soil insights that help every farmer irrigate smarter and grow stronger.

Sensoterra soil moisture meters are designed to make precision irrigation simple for every grower. Each wireless sensor measures the moisture level deep in the soil and sends real-time data to an easy-to-use mobile dashboard — no cables, no maintenance, no guesswork. With a long battery life of up to 10 years, the sensors deliver continuous, reliable insights that help farmers decide exactly when to irrigate. Whether you manage vineyards, almond orchards, or vegetable fields, Sensoterra scales effortlessly to any farm size, providing the data you need to save water, reduce costs, and boost yields.

Example calculation of an almond farm:

– A 1,000-acre almond farm using soil-moisture sensors at a density of one sensor per 15 acres would need 67 sensors.
– At a cost of $300 per sensor per year, the annual investment totals $20,100.
– With average almond revenue of $3,800 per acre and an expected 15% yield increase from optimized irrigation, the farm would earn an additional $570 per acre, resulting in $570,000 extra revenue per year.
– After subtracting sensor costs, the net annual gain is approximately $549,900, demonstrating a very strong return on investment.

Trusted by California Growers

“It took me ages to find a durable and accurate moisture sensor. The sensor is feeding data into the eVineyard platform and it lets me create a model of soil moisture across the different root Zone depths and monitor it to make sure it stays in the proper zone. The vines look a lot healthier this year utilizing the tool with the adjusted soil profile” – Cory Michal, Fallon place wines

Compatible with types of soil in California

Soil Series Region / Typical Crops Texture / Drainage Key Feature for Soil Moisture Sensing
Almendra (Almendra series) Butte County, on alluvial fans — used for orchards (almonds, walnuts) Fine-loamy (≈ loam surface, ~23-24% clay) Well-drained, deep soils — sensors can track moisture across full root zone; low hardpan risk
San Joaquin (San Joaquin series) Central Valley (Fresno, Madera, Merced) — crops include almonds, grapes, oranges Loam to clay subsoil, with underlying duripan (cemented layer) Hardpan can restrict root depth and water percolation — good argument for sensors to identify where moisture builds up or stagnates
Vineyard (Vineyard series) Vineyard lands in California — viticulture soils in lacustrine sediments Very deep, somewhat poorly drained — mixed sediments Moisture retention may be high but drainage slower – sensors help avoid over-watering and root stress
Additional areas (citrus/vegetable areas) Lighter soils for almonds per CDFA Sandy-loam to loam Fast drainage = sensors help avoid under-moisture and over-irrigation

A Breakthrough Partnership: UC Davis

Growing crops in California means dealing with heat, drought and increasing soil salinity, making accurate irrigation decisions more critical than ever. With new UC Davis–validated calibration curves, Sensoterra soil moisture sensors now deliver even more reliable readings for California’s most common soil types.

A research collaboration with the University of California Davis

California farmers face growing challenges with salinity, drought, and changing soil conditions. In partnership with the University of California Davis, Sensoterra has validated how soil type, salinity, and temperature influence moisture readings—and developed new calibration curves for Oso Flaco sand, Columbia loam, and Yolo clay loam. This means growers across California’s diverse soils can now make more accurate irrigation decisions, reduce water waste, and protect crop yields, even in saline-prone regions. With proven performance in local soil conditions and support from one of the world’s leading soil research institutes, Sensoterra gives farmers reliable insights to manage water smarter.

Engineered for U.S. Diverse Soils

From the sandy soils of the Central Valley to the heavy clay of Northern California, Sensoterra sensors are built to perform in every environment. Each device automatically calibrates to local soil types, ensuring accurate moisture readings across vineyards, orchards, and open fields. With connectivity options like LoRaWAN and NB-IoT, the sensors integrate seamlessly with your existing irrigation systems and farm management software. This means you can monitor soil conditions in real time, wherever you are, and make precise irrigation decisions that keep your crops healthy and your resources optimized.
