Case Study 01
AgriWater RainBox — Field Trial

One Year Field Test
at Rancho El Rayo

Guanajuato, Mexico — September 2022 to September 2023

Key Result

Over a one-year period, Rancho El Rayo — the RainBox-treated farm — produced a calculated incremental Return on Investment of 526% over the adjacent control farm, with the RainBox MK3 paying for itself more than five times over.

This report covers the harvest period September 2022 to September 2023 at the El Rayo Farm in Guanajuato, Mexico. The farm is one of 13 operated by Agropecuria El Sagrado, a successful grower for Taylor Farms of Mexico.

A RainBox MK3 was installed in July 2022 to treat the highly mineralised well water and to improve soil growing conditions with a goal of increasing crop yields. Six crops were grown on 43 hectares (104 acres) consisting of multiple individual adjacent plots: romaine lettuce, cauliflower, broccoli, corn, spinach, and green beans.

Control & Methodology

The Control Farm

The control used was an adjacent farm, also operated by El Sagrado, irrigated from a different well and without a RainBox. Initial soil conditions, ongoing weather conditions, and fertiliser inputs were all identical across both farms, ensuring that the RainBox was the only variable between the two operations.

Methodology — Dr. Roberto Maurer
Select the best yielding plot from each of the six crops from both farms
Calculate the yield per hectare of treated and untreated for each crop
Calculate the yield difference per hectare for each crop
Multiply by price paid by the customer to calculate incremental revenue per hectare
Multiply by hectares used at El Rayo for each crop to arrive at total incremental revenue

Key Analytics

Crop Turnover Rate

Agropecuria El Sagrado achieved a crop turnover rate of 2.36 times in the twelve-month period — equivalent to more than two full growing seasons in Canada. The analysis notes that results of this kind are achievable by any Mexican farmer applying similarly robust cultivation methods in conjunction with the RainBox technology.

Resilience Under Weather Stress

The corn crop suffered significant hail damage during the growing season, yielding zero incremental return. Critically, this affected both farms equally. The RainBox-treated farm was nevertheless able to generate a positive overall incremental return of $2,174 per hectare across all six crops, including the zeroed corn — demonstrating the technology's ability to deliver strong aggregate outcomes even when individual crops are compromised by weather events outside any farmer's control.

Soil Scout Integration

Three Soil Scout moisture sensors were installed to track moisture levels across the farm and provide twelve months of data for a smartphone application enabling the farmer to manage irrigation start time and duration with precision. The integration was highly successful, pointing to strong potential for Soil Scout and RainBox to be deployed together as a precision irrigation management system.

Market Context

The Mexican agricultural market is extremely competitive, where poor seasonal results can mean operational failure. The RainBox is positioned to make the decisive difference between a marginal and a profitable growing season. The verifiable results from El Rayo are expected to motivate both individual farmers and processors reliant on a consistent supply of high-quality produce. The report identifies at least 30 major producers who, between them, could order 50 to 60 units for testing — to be followed by larger-scale adoption once field results are verified.
