20 Years of Enclosure-Free Irrigation Model: Shandong Jintain’s Pioneering Technology Serves Over 700,000 Farming Households

Pioneering a New Irrigation Model

Founded in 2002 and headquartered in Jinan's Laiwu High-tech Zone, the company first deployed high-frequency RF card control technology to agricultural water-saving irrigation in 2003. At that time, traditional well irrigation required constructing costly pump houses that occupied arable land and demanded significant labor. Shandong Jintian's solution eliminated the need for these structures altogether, introducing what became known across Shandong's well-irrigated areas as the "Enclosure-Free RF Card Controller Well Irrigation Model"—a first for the province.

By 2004, the system had secured a national utility model patent and was being promoted for technological application in water conservancy well-irrigation zones, earning widespread acclaim for its implementation in agricultural development projects under the World Bank's Phase III funding.

Ecosystem Benefits and Economic Impact

The enclosure-free design addresses multiple pain points for farming communities. With no well house to construct, the system eliminates the need to sacrifice cultivated land for irrigation infrastructure. A 2015 industry analysis estimated that across Shandong's well-irrigated areas, installing enclosure-free RF card controllers could save RMB 120 million in construction costs annually for every 60,000 new wells dug that year. With each well house occupying approximately 15 square meters including access roads and shade structures, the model could preserve 1,350 mu (approx. 90 hectares) of farmland each year.

Water conservation is equally compelling. The province's annual groundwater extraction of 8 billion cubic meters, coupled with a 15% per-well water-saving rate, translates into potential annual water savings of 120 million cubic meters. Moreover, as reported by Linyi municipal authorities, farms using this smart RF card irrigation achieve water savings at about half the cost of traditional methods, while the county's 288,000 mu (approx. 19,200 hectares) of RF card-irrigated farmland saves over 30 million cubic meters of water each year. A farmer in Tancheng County captured the experience succinctly in a 2025 interview: "Before, watering the wheat fields was exhausting—I had to haul a tractor, set up a pump, and lay pipes for days. Now, with just a swipe of my card, the water flows right out. It's truly convenient and effortless!"

From RF Cards to Smart Evolution

While the original RF card system automated irrigation, Shandong Jintian has since advanced its technology significantly. The sixth-generation product—a wireless communication terminal remote intelligent irrigation control device—has been granted a national invention patent, marking a leap from localized card-based control to remotely accessible management.

The company's Smart Water Price Processor series supports agricultural water pricing reform initiatives nationwide by providing digital water rights management and progressive pricing capabilities—tools that help translate national policy into on-the-ground water savings. In 2024, the Ministry of Water Resources issued a directive to accelerate the measurement and management of agricultural well irrigation based on electricity consumption, a technology Shandong Jintian had already pioneered and deployed in reform projects seven years earlier.

Nationwide Reach and Future Outlook

From its origins in Shandong, the enclosure-free irrigation model has expanded to provinces including Xinjiang, Inner Mongolia, Henan, Hebei, Hubei, Jiangsu, and the three northeastern provinces. Within Shandong, the technology has been adopted across more than 60 counties and districts. The company was invited as the primary drafting unit for the Shandong Provincial Standard DB37/T 2733-2015 before also serving as the principal drafter of the national standard GB/T 40119-2021, which was released on May 21, 2021 and took effect on December 1 of the same year—solidifying Shandong Jintian's role in standardizing China's RF card irrigation sector.

"The enclosure-free RF card irrigation model emerged from a practical need to reduce infrastructure costs while making irrigation accessible and controllable for individual farmers. It has proven its value by being simple to use, low-maintenance, and easily adoptable across large regions," said a company representative. "As we look ahead, we continue to integrate remote monitoring and water rights management, ensuring that our technology not only saves water but also empowers sustainable agricultural transformation."

With 23 years of industry experience and a portfolio of 54 patents, Shandong Jintian remains committed to delivering smart, scalable irrigation solutions that serve both China's farmers and global markets.
