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: .
