“…Other bioenergy byproducts with highly available C have also found to cause a short-term immobilization of N [1]. Dehydrogenase is an intracellular enzyme participating in the biological oxidation of organic compounds in soil [37] and is frequently reported to be related to the organic matter availability in the soil [28,38]. In the few studies identifying the impact of biochar on soil enzymes, there are discrepancies and inconsistencies among the documented findings.…”

“…Soil total N and P contents were determined by sulfuric acid peroxide digest. Dehydrogenase activity analysis involved the reduction of 2,3,5-triphenylterazolium chloride (TTC) to triphenyle formazan (TPF) as described by Casida et al [27], with slight modification [28]. Briefly, 3 mL water and 3 mL TTC were added to 3 g of air-dried soil (<2 mm) and incubated for 24 h in darkness at 37˝C.…”

Abstract:The bioenergy industry produces a wide range of byproducts varying in their chemical composition depending on type of technology employed. In particular, pyrolysis and transesterification conversion processes generate C-rich byproducts of biochar (BC) and glycerol (GL), respectively, which can be added to soil. These two byproducts vary in their carbon availability, and comparing their effects when added to agricultural soil deserves attention. This study investigated the immediate and residual effects of a single application of BC and GL to a cultivated Brown Chernozem soil from the semi-arid region of southwestern Saskatchewan, Canada. In the first season following addition of amendments, BC and GL alone had no significant impact on all measured parameters. However, when combined with 50 kg urea N¨ha´1 (BC + UR), the yields obtained were similar to those with 100 kg urea N¨ha´1 alone. The GL with urea N (GL + UR) treatment had reduced crop yield and N uptake compared to urea alone in the year of application attributed to N immobilization, but had a positive residual effect in the second year due to remineralization. Both GL and GL + UR treatments enhanced dehydrogenase activity compared to other treatments whereas BC + UR tended to decrease microbial biomass C. The crop and soil response to application of biochar was less than observed in previous studies conducted elsewhere. Direct and residual effects of glycerol addition on the crop were more evident. An application rate greater than 2.8 t¨ha´1 and 3.5 t¨ha´1 for BC and GL, respectively, may be required to induce larger responses.

“…At the end of incubation, NO) --N in soils was then extracted with 0.5 mol L -I K 2 S0 4 for 1 h and the concentration was determined by an automated procedure (Autoanalyzer II, BRAN + LUEBBE, Norderstedt, Germany). Soil dehydrogenase activity was determined by the reduction of 2,3,5-triphenyltetrazolium chloride (TTC) to triphenylformazan (TPF) , as described by Serra-Wittling et al (1995) with modifications. Briefly, moist soil (4 g) was incubated at 37T for 24 h in darkness after 2 mL of 1% TTC and 2 mL of 1 % glucose solution were added.…”

“…Duplicate field-moist soil samples (1 g) were incubated at 378C for 1 h and the r-nitrophenol released was measured at 420 nm by spectrophotometry (Hitachi Corp., Tokyo, Japan). Dehydrogenase activity was determined according to the method described by Serra-Wittling et al (1995). Triplicate field-moist soil samples (5 g) were incubated at 378C for 24 h in the presence of triphenyltetrazolium chloride.…”

Lalande, R., Gagnon, B. and Royer, I. 2009. Impact of natural or industrial liming materials on soil properties and microbial activity. Can. J. Soil Sci. 89: 209Á222. Soil acidity is a major problem in agriculture because it limits plant growth and reduces crop productivity. The neutralizing potential of industrial by-products and their impact on soil properties were evaluated in two acidic soils characterized by contrasting textures, and submitted to intensive agriculture practices. Soil pH, microbial (dehydrogenase and alkaline phosphatase) activity, and Mehlich-3 extractable P, K, Ca and Mg were monitored in the year of soil incorporation of eight liming products and in the following 2 yr. In the sandy loam, liming products did not result in significant increases in soil pH in the 0-to 7.5-cm soil layer. Lime mud (LM) significantly increased soil pH by 0.4 units in the 7.5-to 20-cm layer compared with cement kiln dust (CKD). In the silty clay, calciumÁ phosphateÁmagnesium (CalPoMag) significantly raised pH by 0.65 units over both natural calcitic lime (NCa) and the magnesium dissolution product (MgD) in the first soil layer, and by 0.5 units over carbide lime (CL) treatment in the second soil layer. Activities of dehydrogenase and alkaline phosphatase were increased to various degrees by all liming materials, especially on the silty clay; LM and CalPoMag were the most beneficial materials. The exception was MgD, which did not result in any impact on microbial activity relative to the control. Both enzymatic activities were related to the increase in soil pH, particularly the alkaline phosphatase. Ion leaching was more pronounced in the sandy loam than in the silty clay soil, where large differences in the Ca and Mg ion levels were still detected in the 20-to 40-cm layer of the sandy loam. In this study, LM and CalPoMag are interesting liming products, particularly in the silty clay soil.
