2,Granular Technology Advantage - High Tower Granulation Process

NPK 21-6-13 is manufactured using the high tower granulation process, offering the following benefits:

• Uniform Granule Size: Ensures consistent application and even distribution of nutrients in the soil.
• Enhanced Durability: The granules are robust and resistant to crumbling, reducing losses during transportation and handling.
• Controlled Nutrient Release: The slow, steady release of nutrients provides plants with a reliable nutrient source while reducing nutrient leaching and runoff.

3,Formulation Advantages with Nitrate Nitrogen & SOP

This fertilizer combines ~8% nitrate nitrogen and chloride-free sulfate of potash (SOP) to deliver superior performance:

• Quick Nitrogen Uptake: Nitrate nitrogen is water-soluble and immediately available for plant uptake, promoting rapid vegetative growth during critical stages.
• Balanced Potassium Supply: Potassium from SOP (sulfate of potash) is chloride-free, enhancing stress resistance, improving crop quality, and supporting photosynthesis without the harmful effects of chloride.
• Phosphorus for Root Development: The 6% phosphorus content supports robust root establishment, leading to better nutrient and water uptake.

4,Ideal Nutrient Balance for Versatile Crop Use

NPK 21-6-13 offers a balanced nutrient profile that promotes strong vegetative growth and supports reproductive stages for a variety of crops:

• Nitrogen (21%): Encourages lush foliage and vigorous growth.
• Phosphorus (6%): Aids in root development and flowering.
• Potassium (13%): Strengthens plant cells, improves drought tolerance, and enhances fruit and seed quality.

5,Recommended Crops & Application Guidelines

NPK 21-6-13 is suitable for a wide range of crops, including:

1. Vegetables (Tomatoes, Peppers, Cucumbers)
   Application Rate: 250-350 kg/ha
   Usage: Apply before planting and during early flowering/fruit setting to ensure strong growth and enhance fruit quality.

2. Field Crops (Corn, Wheat, Soybeans)
   Application Rate: 200-300 kg/ha
   Usage: Apply at planting or early vegetative stages to boost growth and yield potential.

3. Fruit Trees (Citrus, Apples, Grapes)
   Application Rate: 400-600 kg/ha
   Usage: Apply during early spring and mid-season to support flowering, fruit development, and stress resistance.

6,General Application Tips:

• Irrigation: For best results, water the field thoroughly after application to help dissolve the fertilizer and improve nutrient availability.
• Soil Testing: Regular soil analysis is recommended to optimize the application rates and ensure the best crop response.

7,Conclusion:

NPK 21-6-13, with its ~8% nitrate nitrogen and chloride-free SOP, is a high-performance fertilizer suitable for a variety of crops. It delivers a balanced supply of nutrients, supporting robust growth, strong root systems, and high-quality yield. This versatile fertilizer ensures that your crops receive the nutrients they need at critical growth stages.

Choose NPK 21-6-13 fertilizer for healthy crops, higher yields, and improved stress resistance throughout the growing season.
