Integrating a fertigation system into an existing watering system is feasible and beneficial for efficient nutrient delivery to plants. Fertigation combines irrigation and fertilization, allowing for precise control of nutrient application. To fuse a fertigation system, assess your current irrigation setup, ensure compatibility, and potentially upgrade components like pumps and injectors. Proper calibration and monitoring are essential to prevent over-fertilization and ensure uniform nutrient distribution. This integration can enhance plant health, save time, and reduce fertilizer waste.
