“…However, studies evaluating the first years of biochar applications and their relationship to the microbial community have received less attention than its influences on soil physicochemical properties [2,8]. Our previous study showed that the first two years of pinewood biochar application to the sandy soil investigated experienced an 18% increase in TC, and showed signs of improvements in C sequestration and SOM dynamics [33]. The TC increase in biochar incorporated (10%-Inc) in the 0-15 cm soils support claims reported in other studies that suggest a contributing role of biochar in C sequestration [8].…”

“…Selected chemical analysis performed on all soil samples included gravimetric soil moisture, total C (TC) and total N (TN) content, active C (POXC), and pH analyses were published previously [33]. Briefly, gravimetric soil moisture was determined on 10 g subsamples by oven-drying at 105 • C for 24 h and subsequently used for soil dry weight correction.…”

“…The physicochemical properties of the soil samples are shown in Supplementary Table S1. The complete analysis of soil TC, TN, and POXC is discussed in Frene et al [33]. Briefly, the TC in the soils collected at 0-15 cm depth varied in response to the biochar application rates (p = 0.0116).…”

“…This project's related work has already demonstrated that pinewood biochar increased TC and macro-aggregates fractions, while active C decreased. Moreover, biochar significantly increased soil activity, as revealed by the biogeochemical cycle index, CNPS activity [33].…”

“…Soil physicochemical properties, including the SOM dynamics, were also used to explore the potential mechanisms influencing the changes in the soil microbial community. Based on previous results [33], we hypothesized that biochar would alter the soil microbial community structure and the soil EAs involved in nutrient cycling based on the depth of incorporation (incorporation and surface) and application rates (5% and 10%).…”

Biochar offers several benefits as a soil amendment, including increased soil fertility, carbon sequestration, and water-holding capacity in nutrient-poor soils. In this study, soil samples with and without biochar additives were collected for two consecutive years from an experimental field plot to examine its effect on the microbial community structure and functions in sandy soils under peach-trees (Prunus persica). The four treatments evaluated consisted of two different rates of biochar incorporated into the soil (5%, and 10%, v/v), one “dynamic” surface application of biochar, and a 0% biochar control. Fatty acid methyl ester (FAME) analysis was used to assess the microbial community structure, and enzyme activities involved in C, N, P, and S nutrient cycling were used as a means of assessing soil functionality. Total FAME and bacterial indicators increased by 18% and 12%, respectively, in the 10% incorporated and 5% surface applied treatments. Biochar applications increased β-glucosaminidase and arylsulfatase activities, 5–30% and 12–46%, respectively. β-glucosidase and acid phosphatase activities decreased by approximately 18–35% and 5–22% in the 0–15 cm soils. The overall results suggest that biochar’s addition to the sandy soils stimulated microbial activity, contributing to the increased mean weight diameter (MWD), C sequestration, and consequential soil health. The changes in microbial community structure and functions may be useful predictors of modifications in soil organic matter (SOM) dynamics due to the long-term application of pine biochar in these systems.

The production of bioproduct feedstocks such as switchgrass (Panicum virgatum L.) and willow (Salix spp.) on degraded lands provides an opportunity to grow dedicated bioenergy crops with the potential to capture and store carbon in the soil while reducing competition with land for food production. However, how the production of these crops alters plant–soil–microbe interactions that govern soil C accumulation in highly degraded soil is underexplored. The objectives of this study were to examine select biological and chemical properties related to stable soil organic matter (SOM) production from the growth of switchgrass and willow on marginal soil over two growing seasons and whether biochar amendment can positively affect these parameters. To address our objectives, paired former surface mined lands and non‐mine impacted marginal agriculture sites were selected across West Virginia, USA, and biochar and unamended control treatments were imposed. Through the first two growing seasons, microbial activity and demand for carbon (C) increased and was accompanied by a shift in extracellular enzyme investment for decomposition‐associated enzymes. Mineral‐associated organic matter C increased over the two growing seasons, and this increase was greater in the mine sites compared to the agriculture sites. Compared to each site's previous land use, C losses were observed under bioproduct systems in the agriculture, but not the mine sites. Biochar amendments did not impact microbial activity but did increase the C:N of SOM. Overall, our results suggest that the early growth of switchgrass and willow can result in C accumulation in marginal and highly degraded lands.
