Abstract
Studies on the Use of Locally Available Renewable Seaweed Wastes from Cox's Bazar and Saint Martin as Compost Organic Fertilizer Resources
This study evaluates the potential of Hypnea species, a red seaweed abundant along the coasts of Cox's Bazar and Saint Martin, Bangladesh, as a sustainable organic compost fertilizer. Rich in essential macronutrients (K, N, P), micronutrients (Fe, Zn, Mn), and bioactive compounds (carrageenan, auxins, cytokinins), Hypnea enhances soil health, plant growth, and crop yield. Its composting process is efficient, with rapid biodegradation and microbial activity producing nutrient-rich humus that improves soil structure, moisture retention, and pH balance while increasing plant resilience to drought and salinity. A six month field experiment in Sreemangal’s Khasia farming community tested three treatments: T1 (control), T2 (25g seaweed compost per tree), and T3 (50g seaweed compost per tree). The highest betel leaf yield was observed in T3 (2880 leaves/day), significantly surpassing T1 and T2 (2780 leaves/day; ANOVA: F = 14822.79, p ≈ 8.84 × 10??²). These findings demonstrate the economic viability of Hypnea-based compost as an alternative to chemical fertilizers, aligning with sustainability goals and the blue economy framework. Furthermore, sustainable seaweed waste management supports nutrient cycling, soil enrichment, and biodiversity, reducing environmental pollution while benefiting both marine and terrestrial ecosystems.
