"We examined the effect of biochar application to different soils on crop growth, phosphorus and nitrogen balances under greenhouse conditions in Thua Thien Hue Province, Vietnam. Results showed that : (1) Komatsuna growth in sandy soil less than clay and organic soils. Biochar improved crop yield in clay and organic soils, but it did not improve in sandy soil. (2) Biochar increased P and N uptake in leaves and roots in clay and organic soils. (3) Biochar reduced P leaching; furthermore biochar reduced TN leaching in organic soil. Besides, biochar reduced NO3-N leaching in clay and organic soils. We further study the N dynamics in soil treated with biochar materials."
