Biofertilizers Production from Lignocellulosic Biomass

Abstract

The addition of fertilizers to soil improves its physical and biological conditions and maintains its nutrient richness. That's why they have long been used to enhance the plants natural growth and for the rehabilitation of contaminated soils. This study assesses the effects of biochar, compost, and digestate sourced from lignocellulosic biomass on soil and plant parameters. Biochar demonstrated pH improvement by reducing soil acidity, contrasting with compost that reduced soil pH levels. Biochar-amended soil exhibited lower metal concentrations compared to compost-amended soil. Biochar modalities displayed higher germination rates, while a blend of biochar and compost notably enhanced plant biomass. Moreover, the digestate showcased a balanced C/N ratio, signifying its potential as a nitrogen-rich fertilizer. These findings underscore the efficacy of lignocellulosic-based biofertilizers in bolstering soil quality and fostering optimal plant growth
