Title: A Sustainable Approach to Improve Soil Health. A Case Study for Western Bulgaria
Keywords: biochar, smart sustainable agriculture, soil

Abstract: The study investigates the effects of biochar, produced from alfalfa at 400°C and 600°C, on soil health in Western Bulgaria. Eleven soil samples were analyzed for pH, nitrate, phosphate, and potassium levels before and after biochar application. Results indicated that biochar improved phosphorus and potassium levels, essential for crop growth, while maintaining stable nitrate content, thus promoting sustainable agriculture. The research highlights biochar's potential to enhance soil fertility, reduce chemical fertilizer use, and support environmentally friendly farming practices, contributing to better soil management and carbon sequestration efforts.
