2, Granular Technology Advantage - High Tower Granulation Process

NPK 15-5-15 is manufactured using the high tower granulation process, which provides several benefits:

• Uniform Granule Size: Ensures even nutrient distribution and smooth application with minimal dust formation.
• Durable & Efficient: Granules are resistant to breaking or crumbling, making them easier to transport, store, and apply with both manual and mechanical spreaders.
• Controlled Nutrient Release: Provides a steady, controlled release of nutrients for better plant uptake and reduced nutrient loss.

3, Nitrate Nitrogen & Sulfate-Based Formula: Quick-Action and Long-Term Benefits

This fertilizer utilizes nitrate nitrogen (a readily available and easily absorbed nitrogen form) and sulfate-based potassium (SOP), offering multiple advantages:

• Quick Nitrogen Uptake: Nitrate nitrogen is immediately available to plants, promoting fast initial growth, green foliage, and enhanced photosynthesis.
• Sulfate of Potash (SOP): The potassium is sourced from SOP, which is chloride-free, making it especially suitable for crops sensitive to chloride. SOP also enhances potassium absorption, promoting stronger root systems, improved stress resistance, and better crop quality.
• Balanced and Efficient: The combination of nitrate nitrogen and sulfate potash delivers a balanced nutrient profile that supports plant growth without overstimulating vegetative growth, perfect for a variety of crops.

4, Recommended Crops & Application Guidelines

NPK 15-5-15 is a versatile fertilizer suitable for a variety of crops, especially those requiring balanced nitrogen and potassium for both vegetative growth and fruiting stages. Below are the recommended crops and usage guidelines:

• Leafy Vegetables (Lettuce, Spinach, Kale)
  Application Rate: 250-350 kg/ha
  Usage: Apply during the early growth phase, especially when plants are actively developing leaves. A split application can be beneficial to support continuous healthy growth.

• Fruiting Crops (Tomatoes, Peppers, Cucumbers)
  Application Rate: 300-400 kg/ha
  Usage: Apply before planting and during early flowering/fruit setting. The combination of nitrate nitrogen and potassium will boost fruit size, quality, and yield.

• Field Crops (Corn, Wheat, Rice)
  Application Rate: 200-300 kg/ha
  Usage: Apply at planting or during the early stages of growth. The fertilizer supports both early vegetative growth and continued plant development, enhancing crop productivity.

5, General Application Tips:

• Irrigation: Water thoroughly after application to ensure the fertilizer dissolves and reaches the root zone for efficient uptake.
• Soil Testing: Regular soil tests can help tailor the fertilizer application to meet specific crop nutrient requirements and soil conditions.
