FERTIZER 15-5-25+4MgO+13SO3+TE is a high-efficiency, water-soluble fertilizer formulated to provide optimal nutrition for fruiting, flowering, and high-yield crops. With a balanced ratio of nitrogen (N), phosphorus (P), and potassium (K), plus essential magnesium (MgO), sulfur (SO3), and trace elements (TE), this fertilizer enhances plant vigor, improves chlorophyll production, and boosts crop productivity.

Its high potassium content (25% K2O) ensures strong fruit development, increased sugar accumulation, and improved drought and disease resistance, making it ideal for vegetables, fruit trees, and greenhouse crops. The addition of magnesium (Mg) and sulfur (S) further enhances photosynthesis, enzyme activation, and nutrient absorption.

Application Recommendations

  • Soil Application: 2-4 kg/da. Adjust the rate based on the specific needs of the crop and growth stage.
  • Foliar Application: 200-400 g/100L. Apply 3 times every 7-10 days during the active growth phase.
  • Best Practices:
    • Use during early mornings or late afternoons for foliar applications to maximize absorption.
    • Avoid mixing with calcium-based or sulfate-based fertilizers.
    • Conduct regular soil and tissue analyses to fine-tune application rates.

Packaging Options

Available in:

  • 1 kg and 5 kg packages for small-scale and home gardening.
  • 25 kg packages for large-scale farming operations.

General Storage Guidelines

  • Protect the fertilizer from frost, direct sunlight, and moisture.
  • Store loose materials indoors rather than in open areas. Keep doors closed and cover any heaped materials.
  • Since the product is moisture-sensitive, ensure protection from rain and standing water.
  • Follow hazardous material labels on the packaging where applicable.
  • Do not stack more than two pallets. Store only in the original packaging and use the product as soon as possible after opening.

Storage Temperature

  • Avoid exposure to frost and extreme heat.
  • Prevent significant temperature fluctuations during storage.
