The application of water-soluble fertilizers is crucial in agricultural cultivation. To maintain the healthy growth of crops, it is necessary to provide them with sufficient water and nutrients. Currently, many agricultural planting processes lack a standardized fertilization practice, which often leads to over-fertilization of the soil and issues with excessive water and fertilizer. To reduce such occurrences, many farmers are now turning to integrated water and fertilizer systems in their fields, making fertilization and irrigation more intelligent.

Integrated technology is a new agricultural technique that combines irrigation and fertilization. It integrates the soluble solid or liquid fertilizers with irrigation water through a pressure system (or natural terrain gradient), then combines the water and fertilizer before being sprayed evenly, at regular intervals, and in precise amounts in the crop growing area. This maintains the soil in the main development zone loose and with suitable moisture content. Additionally, it designs the requirements for different growth stages based on the characteristics of fertilizer needs, soil environment, nutrient content, and regularities, regularly quantifying water and nutrients and supplying them directly to the crops in proportion. The integrated system can also monitor irrigation in real-time and automatically control irrigation water supply time, fertilizer concentration, and flow rate. During the development of the integrated instruments, the entire system works in harmony, significantly increasing the efficiency of irrigation water usage and meeting reasonable irrigation requirements.

Integrated water and fertilizer application is a system that can be placed in various locations, suitable for both facility agriculture and large fields, enhancing the efficiency and accuracy of farmland production. This integration represents a new agricultural technology that combines irrigation and fertilization. It can be mixed with water and fertilizer based on soil nutrient content and the specific fertilizer requirements of crops. Proper irrigation ensures that fertilizers are absorbed by the crop's root system without being lost in the deeper soil layers. It not only meets the water and fertilizer needs for crop growth but also increases the utilization of water and fertilizers and protects groundwater from the impact of chemicals.
