Biochar is the carbonaceous material produced by the pyrolysis of organic material (plant/animal) which can be used for long term storage of C and as soil conditioner. The steady decrease in fertility by continuous cultivation practices is compensated by the addition of fertilizers but decrease in SOC is a serious issue. Only biochar can slow or reverse this trend. Three types of biochar viz :- pine needle biochar, poultry biochar and bagasse biochar were prepared at 500ÂșC. The experimental study include 6 treatment : T1 - control, T2 - Pine needle biochar treatment, T3 - Poultry biochar treatment, T4 - Bagasse biochar treatment, T5 - Mixed biochar treatment and T6 - urea treatment. The effect of biochar on chemical properties were determined and it was found that biochar significantly increased the SOC, SOM, total N, available P, available K, exchangeable cations - Ca2+, Mg2+ and Na+. Micronutrients Fe and Mn increases while Zn decreases and Cu concentration was not significantly affected. The data was analyzed by applying Tukey HSD test of post hoc treatment in SPSS 16.00 Software package. Thus the study indicates that biochar can be used as a reclamation for acidic soil, increases nutrient retention, decreases need of chemical fertilizers and can be regarded as best environment friendly soil conditioner. - See more at: .
