Soil dehydrogenase activity

Soil salinity is a critical threat to global agriculture. In plants, the accumulation of xanthine activates xanthine dehydrogenase (XDH), which catalyses the oxidation/conversion of xanthine to uric acid to remove excess reactive oxygen species (ROS).

Soil microorganisms are supportive in the transformation of soil phosphorus (P) and are thus an important component of the soil P cycle. These are effective in releasing P both from inorganic and organic pools of total soil P through their respective solubilizing and also enhance the soil microbial and enzymatic activities.

A field experiment was carried out at Assam Agricultural University, Jorhat (Assam) in direct seeded rice (DSR) during autumn, 2018. The treatments consisted of three Plant growth-promoting rhizobacteria (PGPR) inoculations viz., Bacillus cereus, Pseudomonas fluorescens and no inoculation and four weed management practices viz., pretilachlor pre-emergence @ 0.75 kg/ha, pretilachlor pre- emergence @ 0.75 kg/ha followed by one hand weeding at 30 DAS, three hand weedings at 15, 30 & 45 DAS and weedy check.

Soil samples collected from two termite mound soils in Anna University campus, Chennai, Tamil Nadu were characterized for the various parameters such as pH, Electrical Conductivity (EC), Total organic carbon (TOC), Nitrogen (N), Phosphorus(P) and Potassium (K)and microbial activity. The dehydrogenase enzyme activity was found to be 25 and 23mg TriphenylFormosan (TPH) mg/g/h respectively for the two termite mound soils.

A field experiment was conducted in clay loam of Wetlands of TNAU farm, Coimbatore to study the impact of nutrient management technologies on Soil Microbial Biomass-Carbon (SMB-C) and Dehydrogenase Activity (DHA) of soil under lowland rice ecosystem. In the present investigation, integration of inorganics, Sesbania aculeata and biofertilizers have intensively triggered the microbial activities, which would have resulted in higher dehydrogenase activity.

The activity of dehydrogenase (µg TPF produced g-1 day-1 ) followed decreasing trend from before treatment imposition to 3 days after treatment imposition thereafter it showed increasing trend. Sulfonyl urea herbicides had the lower dehydrogenase activity immediately after herbicide application as compared to the other herbicide group’s viz., chloroacetamide, triazolepyramidine, pyramidinethiobenzole and aryloxyphenoxy propionate. Urease activity (g of NH4 + released g-1 soil 2 hr-1 ), increased from 0 DAT up to 45 DAT and thereafter it decreased.
