“…Biochar average C and N concentrations were lower in C (78-79%), but within the range reported for N (0.4-0.9%) compared to data reported by Baronti et al (2014) and García-Jaramillo et al (2021). The hypothesis that addition of B+Com or planting cover crop in the vineyard's alleys will increase soil organic C in 0-30 cm soil depth was partially accepted for B+Com, but rejected for cover crop.…”

“…The hypothesis that addition of B+Com or sowing cover crop in the vineyard's alleys will increase soil total N in 0-30 cm soil depth was rejected, as B+Com did not affect, and cover crop reduced soil total N in 0-30 cm soil depth. García-Jaramillo et al (2021) reported an increase in soil total N only in one of the two studied vineyards with 35 Mg ha -1 undervine application of a wood-based biochar in Oregon, USA. Biochar is not considered as a sources of N in literature due to its low concentration of the N (Baronti et al 2014;García-Jaramillo et al 2021).…”

“…The positive effect of B+Com on soil organic C was only in 0-15 cm soil depth. Few studies have evaluated the effect of biochar application on soil C and N in vineyard's alleys (Baronti et al 2014;García-Jaramillo et al 2021) and only one study evaluated the effect B+Com on soil organic C (Niehues 2015). Our findings supported by García-Jaramillo et al ( 2021) who tested the effect of 18 and 35 Mg ha -1 undervine application of a wood-based biochar on soil organic C and total N six-month after application in two pinot Noir vineyards with loam to clay loam soil texture in Oregon, USA.…”

Effects of biochar-compost mixture (B+Com) and cover crop were assessed on soil and grapevine productivity in an irrigated Merlot (Vitis vinifera L.) vineyard in Okanagan Valley, British Columbia (BC), Canada from 2017 to 2020. The experimental design was a factorial arrangement of control, B+Com, cover crop, and combination of cover crop and B+Com (cover crop/B+Com) treatments in alleys with four replications. The B+Com comprised a 1:1 ratio of biochar and compost and was applied at a rate of 22 Mg ha-1 dry-weight basis in May 2017 and 2019. The cover crop consisted of a dryland forage mixture and birds foot trefoil (Lotus corniculatus L.). Biochar-compost treatment did not affect cover crop biomass or tissue C and N concentrations except for a 12% reduction in 2019 biomass. Biochar-compost and cover crop/B+Com increased soil C content averaged across sampling dates by 11 and 17% (P<0.05) only at the 0-15 cm soil depth compared to the control. Cover crop treatment did not affect (P<0.05) soil C content at two soil depths in all sampling dates. The soil N content was not affected by B+Com, decreased by cover crop by average of 12.5% in both soil depths, and increased with cover crop/B+Com by 4% only at the 0-15 cm soil depth averaged across sampling dates (P<0.05). Grape yield was increased by 32% by cover crop/B+Com relative to control only in 2020. The cover crop reduced petiole N and pruning weights in one or two years out of three.

“…Traditionally four of the 15 most common enzymes used as soil health indicators include β-glucosidase (C cycling), Acid phosphatase (P cycling), β-glucosaminidase (C and N cycling), and Arylsulfatase (S cycling). However, as protocols that measure each EA independently could be laborious and the consumption of resources is costly, there is an option in which multiple EAs are assessed simultaneously in the same soil sample to obtain a comparable potential soil biogeochemical-health index, CNPS activity [15] [16]. EAs have distinguished several agricultural management practices and help with redirection management and assessment.…”

Biochar offers several benefits as a soil amendment, including increased soil fertility, carbon sequestration, and water-holding capacity in nutrient-poor soils. Here, we performed a series of enzyme assays on pine biochar-amended soils, comparing multiple enzyme activities (EAs) simultaneously determined in the same soil sample vs. the sum of individual EAs involved in the C, N, S, and P cycles to provide information of the impacts of biochar on biogeochemical cycling. The combination of these four EAs has been considered an indicator of soil health due to their role in the reactions that release bioavailable nutrients in the cycling of C (β-glucosidase), N and C (β-glucosaminidase), P (acid phosphomonoesterase), and S (arylsulfatase) in soils. Comparisons of the theoretical EAs and the CNPS activity assay approaches in the biochar-modified soil revealed similar activity trends with the different concentrations of added biochar. Two years after adding biochar, study results showed the amended soils did not retain more pNP substrate than the un-amended control soils in three different pH buffers (5.5, 5.8, and 6.5) commonly used in EA reactions. Finally, we performed a third experiment to determine if the biochar previously added to the EAs interfered with the reactions' enzyme or substrate. The results indicated that greater activity was measured using the combined assay, which suggests the CNPS activity method was less affected by biochar than the individual EAs. Our findings indicate that the potential soil biochemical-health index, CNPS activity (combination of four enzymes) assay is more robust than the individual EAs and can be used as an alternative tool to monitor soil functioning.
