Description

Secondary Nutrient Fertilizer Detailed Specifications

DONGKWANG Secondary Nutrient Fertilizer provides essential secondary nutrients—calcium (Ca), magnesium (Mg), and sulfur (S)—to strengthen plant cellular structure, enhance nutrient balance, and support healthy development throughout the growing season.
These nutrients play key roles in chlorophyll formation, enzyme activation, root growth, protein synthesis, and nutrient mobility, making secondary nutrient fertilization critical for high-yield and high-quality agricultural production.

Engineered for modern farms, DONGKWANG formulations deliver high availability, strong compatibility with NPK blends, and excellent field performance across diverse soils.

Key Features & Agronomic Advantages

1. Strengthens Plant Structure & Cell Wall Formation

Calcium supports strong cell walls, improving plant rigidity, storage life, and resistance to physiological disorders.

2. Enhances Chlorophyll & Photosynthesis

Magnesium is the central component of chlorophyll, increasing photosynthesis efficiency and overall crop biomass.

3. Improves Nitrogen & Protein Synthesis

Sulfur promotes amino acids, enzymes, and vitamin formation, improving crop quality and protein content.

4. Corrects Secondary Nutrient Deficiencies

Solves Ca, Mg, and S deficiencies common in sandy soils, high-rainfall regions, and intensive cropping systems.

5. Compatible with NPK Programs

Can be applied with base fertilizers or added to blends to improve balanced plant nutrition.

6. Supports Higher Yield & Quality

Improves fruit firmness, sugar content, oil content, color, and grain filling across many crop types.

Field Crops

Maize, wheat, rice, barley, sorghum, canola, soybeans.

Vegetables & Horticulture

Tomatoes, potatoes, leafy greens, onions, peppers, melons.

Fruit Trees & Orchards

Citrus, apples, grapes, bananas, berries, avocados.

Industrial & Plantation Crops

Cotton, sugarcane, coffee, tea, rubber.

Greenhouse & High-Value Crops

Ideal for crops requiring tight nutrient control and consistent Ca–Mg–S supply.

Usage Guidelines

  • Conduct soil and leaf analysis to determine Ca–Mg–S requirements.

  • Apply through broadcasting, top-dressing, fertigation (soluble grade), or incorporation.

  • Combine with NPK fertilizers for balanced nutrient programs.

  • For deficiency correction, apply higher rates in split applications.

  • Avoid mixing calcium fertilizers directly with phosphate or sulfate-rich liquids unless compatibility is confirmed.

Packaging & Storage

  • Packaging: 25 kg / 50 kg woven PP bags, 500–1,000 kg jumbo bags

  • Storage: Store in a cool, dry, ventilated warehouse; protect from moisture and direct sunlight

  • Shelf Life: Stable under proper storage; anti-caking treated for long-term handling
