Description

Granular Seaweed Fertilizer Detailed Specifications

DONGKWANG Granular Seaweed Fertilizer is formulated from high-quality marine seaweed extracts. Each granule contains organic matter, seaweed‑derived polysaccharides (such as alginic acid), trace minerals, and natural growth regulators, providing a sustained source of nutrients and bioactive compounds to improve soil and crop performance.

This formulation increases soil organic carbon, stabilizes soil structure, enhances moisture and nutrient retention, and promotes beneficial microbial activity for long-term soil fertility. Gradual decomposition of granules ensures continuous nutrient supply, stimulating root growth, improving nutrient uptake, and supporting uniform plant development across diverse crops and growing systems.

Key Features & Agronomic Advantages

  • Enhances Soil Structure & Fertility — Organic matter and seaweed polysaccharides improve soil aggregation, porosity, and water retention, providing optimal conditions for root growth and long-term soil fertility.

  • Sustained Nutrient & Bioactive Release — Slow-decomposing granules continuously release essential nutrients and bioactive compounds, supporting ongoing root development and plant growth.

  • Stimulates Root Development & Plant Vigor — Seaweed-derived natural growth regulators and minerals promote robust root systems, improved nutrient absorption, and healthier, more vigorous plants.

  • Improves Stress Tolerance & Crop Resilience — Bioactive compounds enhance plant resilience against drought, salinity, poor soil, and environmental stresses, contributing to stable growth and yield.

  • Promotes Soil Microbial Activity & Long-Term Soil Health — Organic seaweed matter nourishes beneficial microbes, enhancing nutrient cycling, soil biology, and ecosystem stability.

  • Boosts Yield Potential & Crop Quality — Optimized nutrition, improved root health, and enhanced soil conditions increase crop emergence, growth uniformity, yield stability, and produce quality.

  • Pre‑Plant / Base Soil Application: Incorporate granules into soil prior to sowing or transplanting to enhance soil structure and fertility.

  • Top‑Dressing / Mid‑Cycle Fertilization: Apply during crop growth to support roots and maintain nutrient supply, particularly effective for vegetables, fruit trees, and orchards.

  • Soil Restoration & Rehabilitation: Ideal for degraded, sandy, saline, or low-organic soils requiring structural improvement and enhanced microbial activity.

  • General Crop Cultivation: Suitable for cereals, vegetables, fruits, orchards, and landscaping plants in conventional or organic farming systems.

Usage Guidelines

  • Spread granules evenly and incorporate into topsoil or around root zones before planting or during soil preparation.

  • For top-dressing, apply around crop rows or root zones, gently mix into soil or irrigate after application.

  • Adjust dosage according to soil condition, crop type, and growth stage.

  • Combine with NPK or micronutrient fertilizers when additional macro-nutrient supply is required.

  • Maintain adequate soil moisture to facilitate decomposition and nutrient release.

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
