Abstract The overuse of nitrogen fertilizers causes nutrient losses through leaching and volatilization. Replacing them partially with organic alternatives like microalgal biomass offers a sustainable solution, improving soil properties, reducing losses, minimizing environmental harm. We aimed to evaluate the use Spirulina platensisbiomass as partial replacement for chemical in brewing barley cultivation. Trials were conducted replace fertilizer S. platensis based on content. applications included in-row treatments (50% 100%) topdressing (10%, 20%, 40%). In addition, seed treatment trial using extract (5%, v/v) was also performed. maintained quality levels, highlighting its potential multifertilizer. Higher accumulation observed grains in-line lowest level (p<0.05). Greater phosphorus, potassium, calcium, magnesium grain trials that performed conventional (up 0.28%). There no difference productivity between treatments, indicating crop yield not affected by fertilizers. an increase 10% percentage first-quality when compared trial. Thus, fields enhances sustainability while maintaining productivity. Using agro-industrial residues production reduces impact supports economic ecological goals.
