“…In this study, sediment organic carbon mineralization rates and cumulative carbon mineralization amounts in S. alterniflora habitats were larger compared to C. malaccensis habitat, and their values increased with S. alterniflora invasion chronosequences, especially at the surface layer in summer (Figure 3,4,5). Previous studies noted that sediment substrate availabilities were the main factor influencing organic carbon mineralization, and higher substrate contents can stimulate microbial activities and carbon mineralization (Chapman et al, 2019;Tito et al, 2021). Invasive S. alterniflora increased sediment TOC and labile fraction contents (Figure 2), which might be an important reason for the increase in carbon mineralization rates and their cumulative mineralization amounts.…”

Invasive Spartina alterniflora has significant impacts on sediment carbon pool and turnover in the tidal wetlands of estuaries and coasts. Yet, how this exotic S. alterniflora affects sediment organic carbon mineralization dynamics remains poorly understood. In this study, sediment geochemical properties, organic carbon fractions, and mineralization dynamics were examined in a native Cyperus malaccensis habitat and three invasive S. alterniflora habitats (6-, 10-, and 14-year-old) in summer and winter. We found that invasive S. alterniflora generally increased sediment total organic carbon and their labile fraction contents. The organic carbon mineralization rates and cumulative carbon mineralization amounts were significantly influenced by invasive S. alterniflora, and their values increased with this exotic plant invasion chronosequences. The mineralization rates and cumulative mineralization amounts were also characterized by higher values in surface sediment (0 – 10 cm depth) compared to subsurface sediment (10 – 20 cm depth) and by seasonal variations with higher values in summer than in winter. The sediment organic carbon labile fractions, rather than total organic carbon, were the most important factor affecting carbon mineralization dynamics. The cumulative carbon mineralization amounts exhibited an excellent fit to the first-order kinetic equation (R2 ≥ 0.93). The changes in modeled kinetic parameters (potential carbon mineralization amounts (C0) and carbon mineralization rate constant (k)) among these four habitats were similar to carbon mineralization rates, implying invasive S. alterniflora promoted the availabilities of organic compounds for microbial respiration metabolism. Overall, our findings highlighted the importance of S. alterniflora invasion in accelerating organic carbon decomposition and carbon dioxide release potential, although it also increases carbon accumulation.

“…Biochar has been used as a soil conditioner, as it reduces acidity and Al availability; increases pH and nutrient availability to plants (P and K, mainly); and influences the physical and water properties of the soil, increasing the field capacity, wilting point and available water (Mendes et al, 2021;Chaves et al, 2020). In addition to adding carbon to the soil, biochar also delays its return to the atmosphere in the form of CO2 (Tito, Fernandes, Chaves, Guerra, & Dantas, 2021).…”

Poultry litter biochar has shown to be promising in crop development and production. On this basis, this study was developed to investigate the influence of increasing rates of poultry litter biochar on the growth and production of maize hybrid BRS 2022. The experiment was laid out in a completely randomized design with six biochar rates (0, 2.0, 4.0, 6.1, 8.1 and 10.1 t ha-1) and four replicates. Plots consisted of pots with a volume of 20 dm3, with one plant each. The following variables were evaluated at 83 days after sowing: plant height; first-ear insertion height; stem diameter; number of leaves; leaf area; internode length and number; stem, leaf and total dry weights; ear weight; grain weight per plant; 1000-grain weight; and ear length and diameter. Biochar application influenced plant height; first-ear insertion height; stem diameter; leaf area; internode length; and stem, leaf and total dry weights, having a positive impact in increasing in ear weight, grain weight per plant, 1000-grain weight and ear length and diameter. For the conditions in which the experiment was conducted, the recommended biochar rate to obtain the best results is 6.4 t ha-1.

Sustainable use of croplands is facing a challenge to maintain organic carbon (C) in soil. Pyrolyzed coal or coal char (CC) is a porous C material produced from the pyrolysis of coal containing high organic C, large surface area, and low bulk density like biochar (BC). This study evaluates corn (Zea mays L.) grain yield and selected soil properties in soil amended with CC and BC at two rates (22 and 44 Mg ha−1) with farmyard manure (FM) (66 Mg ha−1) and without FM addition. This field experiment was performed in sandy loam soil at the University of Wyoming’s Sustainable Agricultural Research and Extension Center (SAREC), Lingle, WY, USA. Two years of field study results indicated CC and BC applied at 22 Mg ha−1 with FM resulted in significantly greater average corn grain yields (13.04–13.57 Mg ha−1) compared to the no char’s treatment (11.42 Mg ha−1). Soil organic matter (SOM) content was significantly greater in the higher application rates of CC and BC than in treatments without chars. Overall, soil nitrate nitrogen (NO3-N), phosphorous (P), and potassium (K) were found significantly greater in CC and BC co-applied with FM treatments. Soil water-holding capacity (WHC) significantly improved in sandy loam soil (up to 27.6% more than the no-char treatment) at a greater concentration of char materials. This study suggests that char materials applied at a moderate rate (22 Mg ha−1) with FM can improve soil properties and crop yield.
