activities. In this experiment, we have utilized four dissimilar feedstocks derived biochar amendments. The highest microbial
biomass carbon was found in Lantana camara (LC) biochar followed by pine needle (PN), maize stalk (MS) and lowest in
black gram (BG) biochar. The dehydrogenase activity in diferent biochar treatment increased signifcantly along with control
with increase in incubation days except pine biochar where dehydrogenase decreased. Biochar application in soil increased
acid phosphatase compared to control. The highest alkaline phosphatase was found in MS and it was 20.56, 31.27, 42.52,
57.62 and 69.56 at 1, 7, 30, 60 and 90 days of incubation, respectively. The highest urease was found in LC followed by BG,
MS and lowest in PN among the biochar at both the biochar application rate. The biochar application augmented the protease
enzyme activity in soil, which might be due to augmenting the accessibility of inorganic nitrogen. The highest fuorescein
diacetate was found in LC and it was 10.12, 17.62, 24.62, 32.86 and 37.56 at 1, 7, 30, 60 and 90 days of incubation, respectively. The increased biological indicator was more at 2.5 t/ha biochar application rate than 5.0 t/ha i.e. lower concentration
of biochar enhanced more than higher concentration. This laboratory study demonstrated that biochar application can proft
incubated acid soils by improving microbial biomass carbon up-lift while increasing potential soil enzyme activityNot Availabl

Experimental and theoretical studies on the corrosion inhibition performance of molecules containing tert-butyl benzyl group on mild steel in acid media
The inhibition by (4-tert-butyl-phenyl)-acetic acid hydrazide (TPAH), 5-(4-tert-butyl-benzyl)-[1,3,4] oxadiazole-2-thiol (TBOT) and 5-(4-tert-butyl-benzyl)-4H-[1,2,4] triazole-3-thiol (TBTT) of mild steel corrosion in 0.5 M HCl was investigated using gravimetric and electrochemical techniques. These inhibitors acted more effectively at higher concentration and at lower temperature; among these TBTT being the most efficient inhibitor, which showed highest efficiency of 92.6% at 303 K and 4.8 mM concentration. Adsorption of TPAH followed Freundlich isotherm, whereas TBOT and TBTT followed Langmuir isotherm. Energy of activation for corrosion increased after the addition of inhibitors. Free energy of adsorption showed that all the three inhibitors get adsorbed to the mild steel surface by both physical and chemical processes. EIS studies confirmed that all the inhibitors offered higher charge transfer resistance to the corrosion current and this led to decreased double-layer capacitance. Polarization studies showed that all inhibitors emerged as mixed type. Surface studies confirmed that the pits caused by corrosion were decreased by protective film of inhibitors. Corelation of experimental data with quantum chemical parameters like ELUMO, energy gap, dipole moment, hardness and softness confirmed the superior performance of TBTT as compared to TPAH and TBOT
