Transforming Cyanobacterial Waste into Effective Organo-Mineral Fertilizers

Abstract:

The present research investigates strategies to alleviate aquatic nutrient enrichment through the upcycling of hypertrophic algal matter, specifically by converting residuals from anaerobic biomethanation into specialized organo-mineral soil amendments. Analytical assessments indicate that these resulting amendments comply with toxicological safety mandates, exhibiting no deleterious heavy metal accumulation. The material possesses a dense nutritional profile, characterized by total nitrogen (6.36%) and phosphorus (2.1%) concentrations, alongside substantial calcium and sulfur fractions essential for crop development. Phyto-stimulatory potential is further augmented by intrinsic humic and fulvic acid concentrations, which facilitate the restoration of soil health and enhance biological productivity. Biological assays involving Triticum durum L. and Pisum sativum L. underscored that growth promotion is strictly governed by application dosage. While elevated concentrations were found to trigger inhibitory effects due to localized osmotic stress, a 1:500 dilution ratio emerged as the peak performance parameter for bolstering seed vitality and plant robustness. To mitigate industrial application challenges, including malodorous emissions and particle aggregation (caking), the integration of natural mineral sorbents – specifically zeolites – is recommended. This optimization enhances the substrate’s physical stability, supporting its strategic deployment in reclaiming anthropogenically damaged landscapes and advancing the circular bioeconomy paradigm.
