biochar soil fertility crop yield arid regions soil amendments nutrient retention

Soil degradation in arid and semi-arid regions poses significant challenges to agriculture, necessitating sustainable management practices that enhance soil fertility while maintaining ecological balance. This study investigates the effects of biochar amendments on soil properties and crop productivity in dryland farming systems. Using a field trial conducted over two growing seasons, we evaluated soil chemistry, moisture retention, and crop yield responses to varying rates of biochar application. The findings indicate that biochar significantly improves soil organic carbon content, enhances nutrient retention, and increases water holding capacity. These improvements translate into higher crop yields, particularly under conditions of water stress. The study concludes that incorporating biochar into soil management practices offers a promising strategy to combat soil degradation and boost agricultural productivity in challenging environments. Further research is recommended to optimize biochar characteristics and application techniques tailored to specific soil and crop conditions.
