Alkaline Mineral Residues from Pulp Mills as a Sustainable and Economical Alternative to Lime Fertilizers

Key Points

• The research aims to evaluate the effectiveness of alkaline mineral residues from pulp mills as a substitute for traditional lime fertilizers in maintaining soil pH.
• Agricultural experiments using alkaline mineral residues
• Comparison with conventional lime fertilizers
• Soil pH measurement and analysis
• Alkaline mineral residues effectively increased soil pH similar to lime.
• Lower costs associated with using pulp mill residues were observed.
• Results indicate potential environmental benefits through reduced lime usage.
