Abstract

Abstract:

Biochar, produced via biomass pyrolysis, is increasingly recognized for its potential in soil health enhancement. This study investigates the impact of compost, biochar blended with sheep manure in 50:50 ratio (BS1), biochar blended with sheep manure and biogas station residue in 33:33:33 (BS2), and 30:50:20 (BS3) ratios on chemical characteristics and organic substances in the leachates, focusing on the interplay between these components. The experimental design included leaching tests with the abovementioned treatments in a controlled environment. Results indicate significant differences in pH, electrical conductivity, and the content of organic substances between the treatments, suggesting that biochar substrates can positively influence physico-chemical characteristics and nutrient dynamics after their incorporation into the soils. Notably, the BS1 demonstrated enhanced water-soluble salts, cold-water-soluble carbon, and humic substances release potential compared to the other studied treatments. Principal component analysis further elucidated the complex relationships between the measured parameters, indicating the importance of biochar-based substrates careful mixing for sustainable agricultural practices to improve soil fertility and carbon sequestration.
