Walnut Orchard Irrigation Systems
Why precision irrigation matters for walnuts
Walnut trees are large and deep-rooted, with a high seasonal water demand. Meeting that demand evenly across big blocks is hard with fixed schedules and manual valves, and both under-watering and over-watering carry a real cost on a crop this valuable.
Precision irrigation replaces calendar watering with continuous monitoring and automated control, so each block gets the right amount of water at the right time across the whole orchard.
Automate your walnut irrigation with WiseConn
WiseConn brings field hardware and the DropControl platform together into a single system for managing irrigation across your whole orchard. Rugged field nodes monitor and control the orchard, while DropControl gives you a web dashboard and a mobile app to manage it from anywhere.
How it works
• Field nodes collect soil moisture, weather and system data and send it into DropControl to help make better informed decisions.
• Data flows to the cloud and is available in real time through the DropControl web platform and mobile app.
• You define irrigation rules and schedules, and the system runs them automatically, opening and closing valves block by block.
• Three roles, one platform: irrigators run day-to-day watering from the mobile app, farm managers make decisions and report from the web, and owners track water use and sustainability.
What growers gain
| Benefit | What it means for your orchard |
|---|---|
| Water savings | Irrigate from real soil and weather data, not a fixed calendar. Growers typically reduce water use by 20 to 40 percent depending on their starting point. |
| Energy savings | Pump only when the orchard needs it and shift watering to lower-cost hours, cutting the energy behind every irrigation cycle. |
| Labor savings | Replace manual valve operation across large walnut blocks with automated control, so a small team can run the whole orchard. |
| Better use of fertilizer | Keep fertigation in the root zone with precise water control, improving nutrient efficiency across the orchard. |
Note: WiseConn does not claim to increase yield or fruit size, since those depend on many factors. The value is in water, energy, labor and fertilizer efficiency, plus full operational control.
Even watering across large blocks
Walnut orchards are often large, with soils that change across the property. WiseConn lets you monitor and control each block independently, so a dry corner or a heavier soil does not force you to over-water the rest of the orchard.
Built to integrate, not replace
WiseConn is designed to work with what you already have. DropControl uses an open architecture, so it connects to the soil moisture probes, weather stations and field sensors you already run, and links to satellite imagery and external platforms through an open API. If you have already invested in sensors or a specific irrigation method, you keep using it and gain a single control layer on top, instead of being locked into a closed ecosystem.
Integrated sensor brands include, among others:
• Soil moisture probes: Sentek, Meter Group (Teros and PHYTOS), CropX, AquaFlex and Enviropro.
• Weather stations and field monitoring: Davis Instruments and iMetOS.
Pricing and return on investment
Walnut is a high-value crop, and an irrigation upgrade pays for itself through the water, energy, labor and fertilizer it saves. There is no single price, because every project is quoted to fit your operation: field size, number of irrigation sectors, the valves you want to control and the sensors you integrate all shape the final figure.
As a guide, projects typically start at around USD 10,000 and reach payback within one to two years. These figures are estimates for a base 40-acre (about 16 hectare) operation. The DropControl platform runs on an annual subscription per node, with a limited free version available, so you can match the investment to the size and ambition of your operation.
Trusted by growers worldwide
More than 3,000 growers use DropControl every day to manage irrigation across thousands of fields around the world, including walnut orchards in California and beyond.

AGRÍCOLA LOS PEUMOS S.A.
Sebastián Divin Larraín, Agricultural Manager at Los Peumos S.A., oversees two farms located between the Maule and Ñuble regions. They cultivate Chandler Walnuts and European Hazelnuts, with the hazelnut varieties being 60% Tonda di Giffoni and 40% Yamhill. The trees were planted in 2016 and 2019, and they use a double-line drip irrigation system with 0.072 inches of precipitation. The farms are equipped with DropControl for irrigation control, humidity sensors, climate monitoring, and well control.
