Abstract

Phosphorous (P) fixation in soils is a serious concern worldwide, and Biochar (B) is gaining attention daily due to its potential benefits for improving the agronomic benefits of applied P. The present study aims to enhance understanding of the P transformation process in a deprived sandy soil following biochar amendments (no-acidified Wheat Straw Biochar (WSB) and chemically modified (acidification with 0.01M C6H8O7 (AWSB)) along with or without P at 250mgkg-1.. A 54-day pot experiment was conducted with two bio-chars levels of 4% (B1), 8% (B2) w/w and control (CK, unamended soil), and two P-levels (without or with P). The results indicate that integration of AWSB with P resulted in increased available P in the soil. We conclude that incorporating acidified wheat straw biochar is a promising practice to potentially improve P availability in deprived soils. Further research is needed to explore site-specific P management for sustainable crop production.
