Shahid, et al (2024) Effect of biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges.

In recent years, biochar—a carbon-rich material produced from organic waste—has garnered attention for its potential to improve soil quality and plant resilience, particularly in drought conditions. A study published in Journal of Pure and Applied Agriculture explores how biochar affects the seed germination and growth of Glycine max L. (soybean) under induced drought stress.

The study tested various treatments with different biochar concentrations, ranging from 10 to 20 tons per hectare, in both normal and drought conditions. Although biochar did not significantly impact seed germination, it contributed positively to plant growth and stress resilience. Soybean plants treated with biochar exhibited improved root and shoot lengths, an increased number of leaves, and better soil moisture retention compared to those without biochar. In drought conditions, biochar enhanced root depth and soil water retention, alleviating the effects of water scarcity.

In addition to physical growth benefits, biochar also improved the biochemical composition of the soybean plants. The treated plants showed higher levels of chlorophyll, proline, and proteins—compounds critical for stress resistance and overall plant health. Biochar’s ability to enhance nutrient availability and soil structure was key to these improvements.

This research highlights biochar’s potential as a sustainable agricultural amendment to improve crop resilience in drought-prone regions. However, further studies are needed to refine biochar application techniques and assess its efficacy across diverse environmental conditions.
