In the present study, we investigated the impact of different combinations of wheat straw biochar, compost and biogas slurry on maize growth, physiology, and nutritional status in less productive soils. The experiment was performed as a completely randomized block design in a greenhouse pot experiment. The compost and biogas slurry were applied with and without biochar. The results revealed that a combination of biochar, compost, and biogas slurry enhanced the cation exchange capacity (31%), carbon (83%), phosphorus (67%) and potassium (81%) contents in the soil. Likewise, a significant increase in soil microbial biomass carbon (15%) and nitrogen (37%) was noticed with the combined use of all organic amendments. Moreover, the combined application of biochar, compost and biogas slurry enhanced soil urease and β-glucosidase activity up to 96% and 67% over control respectively. In addition, plant height, chlorophyll content, water use efficiency and 1000-grain weight were also enhanced up to 54%, 90%, 53% and 21% respectively, with the combined use of all amendments. Here, biochar addition helped to reduce the nutrient losses of compost and biogas slurry as well. It is concluded that biochar application in combination with compost and biogas slurry could be a more sustainable, environment-friendly and cost-effective approach, particularly for less fertile soils.

“…This result agrees with the findings of Zhang et al (2015), who reported a decrease in BG activity in response to the amendment of the biochars (1.5%) obtained from the slow pyrolysis of three feedstocks at 550 °C in a fine-textured clay soil during 206 days of a greenhouse experiment. BG activity also decreased in biochar-amended soils with medium and coarse texture (Wu et al 2013;Chintala et al 2014;Bera et al 2016;Li et al 2018;Günal et al 2018;Teutscherova et al 2018). Conversely, addition of corn biochar to an alkaline clay soil enhanced the activity of BG due to the stimulation of microbial activity (Wu et al 2018).…”

“…This C-hydrolyzing enzyme plays a key role in stimulating microbial growth and activity, and the regulation of the global C cycling and C sequestration in soils (Stott et al 2010;Peregrina et al 2014), but its activity is sensitive to agricultural management practices and changes in environmental conditions (Acosta-Martínez et al 2004;Knight and Dick 2004;Zhang et al 2010;Moscatelli et al 2012) and thus it has been proposed as a good indicator of soil quality (Turner et al 2002;Knight and Dick 2004;Stott et al 2010;Moscatelli et al 2012;Bera et al 2016). Application of different organic amendments including biochar can affect the catalytic behavior of soil BG under different environmental conditions, but the effects were depended on different experimental settings such as the type of soil and biochar (feedstock type), biochar production conditions (pyrolysis temperature and duration, particle size), application rate and the duration of the experiment, laboratory or field conditions (Bera et al 2016;Al Marzooqi and Yousef 2017;Günal et al 2018;Simarani et al 2018;Wu et al 2018).…”

“…Biochar, the end product of pyrolyzed organic feedstocks, can increase (Bailey et al 2011;Paz-Ferreiro et al 2014;Kaurin et al 2018;Simarani et al 2018) or decrease (Zhang et al 2015;Bera et al 2016;Chen et al 2017;Benavente et al 2018;Li et al 2018;Günal et al 2018;Teutscherova et al 2018) the potential activity of BG, but the underlying mechanisms for this variable response are not well understood. Biochar increases the potential activity of BG and other enzyme activities by improving physical (e.g., aggregation, aeration, water retention), chemical (e.g., pH, nutrient addition) and microbial (e.g., labile carbon, microbial activity and biomass, shifts in microbial community structure) properties of soil (Gul et al 2015;Al Marzooqi and Yousef 2017;Khadem and Raiesi 2019;Palansooriya et al 2019), and by improving interactions between enzymes and substrates, and also due to interactions of enzymes with the biochar surface (Daoud et al 2010;Lammirato et al 2011;Lehmann et al 2011;Gul et al 2015;Khadem and Raiesi 2019).…”

Soil β-glucosidase (BG), the rate-limiting enzyme in the final step of cellulose hydrolysis, plays a key role in microbial metabolism, carbon (C) cycling and sequestration in terrestrial ecosystems. Biochar application is known to affect soil BG activity; however, most of the biochar studies have focused on the potential activity of BG, and it is not clear how biochar influences the kinetic and thermodynamic behavior of BG in the soil. The objective of this study was to investigate the effect of maize residue biochar on soil BG kinetic and thermodynamic parameters. Soil BG kinetic (V max and K m ) and thermodynamic (E a , ΔH a and Q 10 ) parameters were determined within soils (clayey and sandy loam soils) amended with either maize residue (as positive control) or its biochar (600 °C) at 0.5 and 1.0% ratios (w/w), and the mixtures were incubated for 90 days. BG showed an increase in potential enzymatic activity (81%), enzyme concentration (higher V max value) (25%) and substrate affinity (lower K m value) (32%) in the biochar-amended sandy loam soil only at high addition rates compared with the control, and an increase by about 86% of the catalytic efficiency (V max /K m ). In the clayey soil, biochar addition decreased potential BG activity (by 10-29%), increased the V max value (by 20-25%) and had no impact on enzyme-substrate binding affinity, but still increased the catalytic efficiency by 47-72%. Adsorption of soil BG by biochar particles did not affect the catalytic efficiency in the soil. Generally, application of maize residue biochar to the soil decreased the E a , ΔH a and Q 10 values of BG compared with the negative controls at both biochar rates in the light-textured soil and only at low biochar rate in heavy-textured soil. The direction and magnitude of BG responses (activity, kinetics, and thermodynamics) to biochar were more related to the soil characteristics. Biochar would increase soil BG thermal stability and decrease its sensitivity to increasing temperature and global warming.

“…On the contrary, high soil moisture levels impede microbial respiration by reducing O 2 diffusion (Moyano et al, 2013). Extracellular enzyme activities that provide information on soil microbial metabolic functioning (Stott et al, 2010) are also strongly influenced by soil moisture (Acosta-Martinez et al, 2007) and soil texture (Günal et al, 2018). Despite the critical role of soil moisture in regulating SOC mineralization, the soil moisture sensitivity of terrestrial C cycling has received less attention in comparison to soil temperature sensitivity (Wang et al, 2019).…”

Soil microbial respiration is one of the largest sources of carbon (C) emissions to the atmosphere in terrestrial ecosystems, which is strongly dependent on multiple environmental variables including soil moisture. Soil moisture content is strongly dependent on soil texture, and the combined effects of texture and moisture on microbial respiration are complex and less explored. Therefore, this study examines the effects of soil moisture on the mineralization of soil organic C Soil organic carbon in three different soils, Ultisol, Alfisol and Vertisol, collected from mixed forests of Georgia, Missouri, and Texas, United States , respectively. A laboratory microcosm experiment was conducted for 90 days under different moisture regimes. Soil respiration was measured weekly, and destructive harvests were conducted at 1, 15, 60, and 90 days after incubation to determine extractable organic C (EOC), phospholipid fatty acid based microbial community, and C-acquiring hydrolytic extracellular enzyme activities (EEA). The highest cumulative respiration in Ultisol was observed at 50% water holding capacity (WHC), in Alfisol at 100% water holding capacity, and in Vertisol at 175% WHC. The trends in Extractable Organic Carbon were opposite to that of cumulative microbial respiration as the moisture levels showing the highest respiration showed the lowest EOC concentration in all soil types. Also, extracellular enzyme activities increased with increase in soil moisture in all soils, however, respiration and EEA showed a decoupled relationship in Ultisol and Alfisol soils. Soil moisture differences did not influence microbial community composition.
