Horticultural biochar, a form of charcoal, serves to enhance soil quality and promote plant growth. This substance is created by subjecting organic materials, such as wood or crop residues, to high-temperature combustion without oxygen, resulting in a durable, porous, and carbon-rich material that can persist in the soil for thousands of years.
Its benefits include improving soil fertility by preventing nutrient leaching and promoting the activity of beneficial soil microorganisms, aiding in the decomposition of organic matter and nitrogen fixation. Additionally, it contributes to enhanced soil structure, diminishing compaction and increasing aeration, thereby supporting improved root growth and water infiltration.
Furthermore, horticultural biochar aids in carbon sequestration by storing carbon in the soil, reducing greenhouse gas emissions from decomposition and fertilizer use. Application methods include direct soil application, mixing with compost or other organic amendments, and serving as a substitute for perlite in container plant potting mixes.
As an eco-friendly and sustainable practice, horticultural biochar emerges as a valuable means to bolster soil health and boost plant productivity in the field of horticulture.
