概要	Fertigation scheduling integrates irrigation and nutrient delivery to optimize plant nutrition while minimizing waste and environmental impact. By applying fertilizers through drip or sprinkler systems at precise times and rates matched to plant development stage and soil water availability, growers can improve nutrient use efficiency, reduce leaching, and boost yields. This method is now standard in commercial vegetable, orchard, and nursery production worldwide.	Hydroponic nutrient solution management involves formulating, monitoring, and adjusting the chemical composition of water-based growing media to deliver optimal nutrition without soil. This method combines analytical chemistry (nutrient analysis, pH, electrical conductivity) with plant physiology to diagnose deficiencies and optimize yield and quality. It is essential for commercial hydroponics, vertical farms, and propagation systems where precision nutrition directly impacts profitability.
