New technology is helping nut growers spray more effectively, especially at hull split

In California’s Central Valley, timing and precision are everything—especially during Hull Split, the most critical spray window of the season for nut growers. With the pressure on and no room for error, visibility into spray performance can make the difference between a successful season and significant crop losses.

That’s where Fieldin comes in.

A Fresno-based company with over a decade of experience serving nut growers, Fieldin has established itself as the gold standard in smart farm operations. With more than 300,000 acres of nut orchards under management, Fieldin’s platform helps growers streamline everything from spraying to mowing and harvesting, delivering actionable insights that improve efficiency and reduce costly mistakes.

Now, Fieldin is expanding its value with cutting-edge spray monitoring technology, just in time for Hull Split.

Introducing Remote Flow Monitoring

Through a new partnership with ARAG and PAS, Fieldin now offers real-time flow monitoring that gives growers precise, in-the-moment visibility into their spray operations. This technology eliminates the guesswork around what was applied and how much, allowing farm managers to make data-driven adjustments on the fly.

“The Hull Split spray is the most important of the season,” says Iftach Birger, Co-Founder and COO of Fieldin. “And when poor coverage means poor control, the risk of significant losses is real.”

Research shows that three factors drive Hull Split spray performance: spray speed, GPA (gallons per acre), and canopy size. With Fieldin’s Remote Flow Monitoring, growers gain live visibility into both spray speed and GPA—the two most critical metrics for Hull Split accuracy—without needing to replace existing equipment or disrupt current workflows.

Real-Time Visibility, Real-World Results

Many growers rely on maps or assumptions to confirm their sprays. But these can be deceiving. In one case, Fieldin’s coverage maps indicated a block was fully treated—but flow data revealed the spray rate dropped near the end, leaving key sections under-treated. In another case, a 20% drop in application rate went undetected until Fieldin’s flow monitoring flagged it in real time.

Without this technology, those issues would have gone unnoticed until it was too late, leading to reduced pest control, weakened nut quality, and potentially a second costly pass.

Fieldin’s solution changes that. With Remote Flow Monitoring, managers can:

• Verify coverage and GPA targets in real time

• Streamline the calibration process

• Identify underperforming machines or crews (e.g., RPM issues or clogged nozzles)

• Avoid missed applications and unnecessary re-sprays

• Protect yield, quality, and long-term resistance management

Easy to Adopt, Built for the Field

Best of all, the system integrates seamlessly with most sprayers and is quick to install. No major equipment changes are required, and Fieldin’s experienced team handles setup and onboarding to ensure success from day one.

Though designed with Hull Split in mind, Remote Flow Monitoring delivers value across every spray event—from post-harvest cleanups to nutrient applications—making it a lasting investment in operational excellence.

“We built this for real-world challenges,” Birger explains. “Growers need control and clarity, not complexity. That’s what we deliver.”

Special Promotion for Hull Split Season

To help new customers prepare for the Hull Split window, Fieldin is offering limited-time introductory pricing for its Remote Flow Monitoring solution.

“This tool pays for itself quickly when you factor in the cost of a missed spray,” Birger says. “We’re here to make sure growers don’t have to take that risk.”
