Water-Saving Irrigation Solutions: Intelligent Control and Integrated Water and Fertilizer Management

Against the backdrop of increasingly scarce agricultural water resources, precision irrigation with intelligent control at its core, combined with integrated water and fertilizer management technology, constitutes the core solution for modern water-saving irrigation. This solution aims to achieve "on-demand water supply and on-demand fertilization" through refined management, maximizing the efficiency of water and fertilizer utilization while ensuring crop growth.

Intelligent control is the "brain" of precision irrigation. The system acquires real-time moisture status of crop roots through monitoring equipment such as soil moisture sensors installed in the field; it also monitors environmental data such as rainfall and evaporation through small weather stations. Based on this real-time data and a preset crop water requirement model, the intelligent irrigation controller can automatically determine when and how much water is needed, and automatically start or stop water pumps and field valves. Managers can also remotely monitor and manually adjust via mobile phone or computer, truly realizing the transformation from "irrigation based on experience" to "irrigation based on data," avoiding the over- or under-irrigation that may occur with traditional timed irrigation.

Integrated water and fertilizer management is the "artery" of precision fertilization. This technology integrates irrigation and fertilization, precisely and evenly delivering soluble fertilizers to crop roots through an irrigation system. The system mainly consists of a fertilizer applicator, a fertilizer storage tank, a filtration device, and an irrigation network. During irrigation, the intelligent control system precisely mixes the fertilizer solution into the irrigation water according to a preset ratio, achieving simultaneous water delivery and fertilization. This not only significantly reduces fertilizer volatilization and loss, improving fertilizer utilization, but also allows for flexible adjustment of fertilizer formulas and dosages according to the needs of different crop growth stages, promoting healthy crop growth and reducing agricultural non-point source pollution.

Deeply integrating intelligent control with integrated water and fertilizer technology can create a highly efficient, closed-loop management system. For example, the system can trigger irrigation based on soil moisture and automatically apply the fertilizer formula required for the current crop growth stage. Practice shows that this integrated solution can achieve comprehensive benefits such as 20%-40% water saving and 30%-50% fertilizer saving, while simultaneously improving crop yield and quality. It is an important technological path to promote resource-saving, environmentally friendly, and sustainable agricultural development.
