Applications:
1. Soil Application: Base application with other fertilizers during land preparation to condition the soil and build a nutrient reservoir.
2. Fertigation/Drip Irrigation: 100% water-soluble, it will not clog filters or emitters. Ideal for continuous feeding through irrigation systems.
3. Foliar Spray: Can be tank-mixed with compatible pesticides and fungicides, providing a direct and rapid nutrient boost through the leaves.
4. Seed Treatment: Soaking seeds or coating them in a solution improves germination rates and encourages strong early seedling development.
Crops & Dosage:
1.For Field Crops (e.g., Corn, Wheat):
(1)Drip or Flood Irrigation: Apply 7.5 to 15 kg per hectare every 15-20 days during the growing season. Use 2-3 times in total.
(2)Foliar Spray: Use a dilution ratio of 1:1500 to 1:2000. Spray 1-2 times from the seedling to the grain-filling stage.
(3)For Cash Crops (e.g., Vegetables, Strawberries):
(4)Drip Irrigation: Apply 4.5 to 7.5 kg per hectare every 10-15 days. Increase the rate slightly to 500-800 grams during flowering and fruiting periods to support heavier yields.
(5) Foliar Spray: Dilute at a 1:1500 to 1:2000 ratio. A single application during both the seedling and flowering stages is effective.
2. For Fruit Trees (e.g., Apple, Citrus):
(1)Soil Application: For mature trees, mix 50-100 grams of flakes with organic fertilizer and apply to the base. For young trees, use half this amount.
(2)Drip Irrigation during the growing season: Apply 10-20 grams per tree (or 15-22.5 kg per hectare). Apply once before flowering and again during the fruiting stage.
3. Specialized Use
Seed Soaking: For improved germination, soak seeds in a solution of 1:500 to 1:800 for 4-6 hours. Be sure to dry the seeds completely before planting.
