China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

The Smart Integrated Water and Fertilizer Irrigation Control System is a new agricultural technology that combines irrigation and fertilization. Integrated water and fertilizer technology uses a pressure system to mix prepared fertilizer solution with irrigation water. Through spray and drip irrigation facilities, it delivers the mixture evenly, at fixed times, and in fixed quantities to the crop development and growth areas. This keeps the soil in the main growth areas consistently loose and at an appropriate moisture content, while adapting to the fertilizer requirements of different crops, soil environmental conditions, and nutrient content levels.
