1. Supplementing Key Nutrients. Although required in small amounts, micronutrients are crucial for plant enzyme activity, photosynthesis, and hormone synthesis. For example:
Iron (Fe): Chlorophyll synthesis, preventing yellow leaf disease.
Zinc (Zn): Promotes auxin synthesis, preventing little leaf disease.
Boron (B): Promotes flowering and fruit setting, preventing flower and fruit drop.
Molybdenum (Mo): Participates in nitrogen metabolism, promoting nitrogen fixation in legumes.
2. Correcting Nutrient Deficiency Symptoms. Quickly alleviates physiological disorders caused by micronutrient deficiencies in the soil (such as terminal bud necrosis and leaf deformities).
3. Enhancing Stress Resistance. Strengthens crop resistance to drought, high temperatures, and pests and diseases.
4. Improving Quality. Water-soluble micronutrient fertilizers can improve fruit color, sugar content, and vitamin content (e.g., boron increases fruit setting rate, and zinc increases grain plumpness).
5. Environmentally Friendly and Highly Efficient. Compared to traditional fertilizers, water-soluble fertilizers have a higher utilization rate (up to 80% or more), which can reduce soil residue and is suitable for precision fertilization such as drip irrigation.
