The Role of Biochar in Improving Soil Quality and Horticulture Crop Performance

Growing awareness of the detrimental effects of synthetic fertilizers and agrochemicals has spurred a shift toward organic inputs in agriculture. Biochar, generated through the pyrolysis process, emerges as a promising organic input, rich in carbon. The thermochemical breakdown of biomass at around 700 °C, irrespective of oxygen presence, produces biochar. Its incorporation into soils offers numerous benefits, including improvements in biological and physicochemical properties. Biochar enhances soil density, pore size distribution, color, pH, nutrient retention, cation exchange capacity, sorption capacity, moisture retention, aeration, and pollution remediation. Notably, it positively influences soil biological properties, impacting the microbial community’s habitat, biomass, enzyme activity, abundance, and diversity. These advantages, encompassing the addition of essential cations, micronutrients, and increased water-holding capacity, position biochar as a potentially cost-effective and eco-friendly solution for horticulture crop production. Properly administered, biochar-treated soil demonstrates positive growth performance in horticultural plants, reinforcing its potential in sustainable agricultural practices.
