Rivulis’ new drip line offers promise for high-yield crops on difficult landscapes

Rivulis, an established provider of advanced irrigation solutions with a global footprint, introduced a new innovation, the D4000 PC drip irrigation system, at the Irrigation Association Show on November 4, 2024 in California, USA. Designed for annual crops like potatoes and tomatoes, the D4000 PC is engineered for efficiency on challenging or sloped terrain. With its advanced pressure-compensated (PC) technology, the system addresses a key barrier for high-value crop growers: ensuring even water distribution across variable landscapes. For the agribusiness sector, this represents a potentially transformative solution as growers seek to optimize yields and resource use, especially in areas previously deemed impractical for drip irrigation.

Addressing Terrain Challenges in Irrigation

Irrigation on hilly or uneven land has long posed operational and financial challenges for the agricultural sector. Standard thin-wall drip lines, which lack pressure compensation, can deliver inconsistent water flow on slopes, leading to inefficiencies in water and fertilizer use and, ultimately, to uneven crop growth. For crops like potatoes and tomatoes that demand consistent watering, these challenges have, until now, constrained growers’ options.

The D4000 PC’s pressure-compensated technology addresses this by maintaining uniform water flow, allowing even distribution across various terrains. According to Rivulis, the system allows for up to 25% longer lateral reach than traditional systems, potentially expanding the productive area in challenging fields. This could prove advantageous for growers seeking to improve output without extensive land preparation or complex irrigation configurations.

An Economic and Sustainable Solution

In an industry driven by cost-efficiency and sustainable practices, the D4000 PC’s design reflects broader trends. By minimizing tubing diameter and extending irrigation reach, the system promises lower material and installation costs—a crucial consideration as input costs rise. Moreover, Rivulis has constructed the D4000 PC from fully recyclable materials, aligning the product with global agricultural trends toward environmental responsibility.

The company’s commitment to sustainability and efficiency echoes the wider industry’s shift toward solutions that balance productivity with environmental stewardship. As water scarcity continues to affect agricultural regions worldwide, systems like the D4000 PC could play an increasingly important role in meeting industry-wide goals for resource efficiency.

Real-World Performance and Flexibility

Early field tests have shown promising results for the D4000 PC, with consistent water distribution maintained even under varying pressure conditions. For instance, in a recent tomato field trial, the system demonstrated uniform water output despite fluctuations in slope-related pressure, suggesting that the D4000 PC could meet performance standards where other systems might falter. With customizable dripper spacing and two flow rate options (0.16 gph and 0.23 gph), the system can be adapted to a variety of crops and soil conditions, providing growers with a tailored approach to irrigation.

The Road Ahead

While the D4000 PC marks a significant advance in drip irrigation, the technology’s real-world impact will depend on adoption and long-term performance under diverse farming conditions. Yet, for many in the agribusiness community, the system’s introduction reflects a step toward overcoming long-standing terrain-related limitations in drip irrigation.

As the sector faces increasing pressure to produce more with less, products like the D4000 PC represent an important option for sustainable agricultural expansion. For growers, the potential to convert previously unusable land into productive acreage may offer a path not only to increased yields but to a more resource-efficient future.
