Application of biochar to soil has increased considerably during recent years
because of its effectiveness as a soil amendment causing beneficial effects on
soil health. However, the effects have been reported to vary and depend
upon types of feedstock and pyrolysis conditions during biochar production.
Therefore, characterization of biochar is extremely important for its efficient
utilization as a soil amendment. In the present study, biochar was prepared
from agro-industrial by-products (rice husk and sugarcane bagasse) and
weeds (Parthenium and Lantana) under similar pyrolysis conditions. Lantana
biochar (LBC) showed the highest pH (10.4) while the lowest value (8.5) being
recorded in rice husk biochar (RHBC). The energy-dispersive X-ray spectroscopy
(EDS) analysis indicated that LBC and Parthenium biochar (PBC) were
superior with respect to potassium (K) content than sugarcane bagasse
biochar (SBBC) and RHBC. The Fourier-Transform Infrared Spectroscopy
(FTIR) study exhibited the existence of different functional groups in biochar.
All the biochar treated soils showed significantly higher microbial activities
with different degrees. Application of LBC and PBC at 4.50 g kg−1 soil
significantly increased K availability in soil. Lantana biochar and PBC amended
the soil at 9 g kg−1 significantly increased the soil pH thus makes these
biochar as potential liming materials.
