“…Then 150-ml headspace gas samples with three replicates were taken after 1 (at 4 h after incubation), 3, 7, 14, 28, 56 and 90 days to analyze soil CO 2 efflux and δ 13 CO 2 . The gas samples at 0 and 4 h after sealing the jars were collected with a gas-tight syringe fitted with a three-way stopcock and transferred into a 200-ml aluminum foil airbag afterwards (Dalian Hede Technologies Ltd., Dalian, China) (Pan, Li, Chapman, Khan, & Yao, 2016). The CO 2 concentration in the headspace was measured by gas chromatography (HP7890A, Agilent Technologies, Santa Clara, CA, USA), and the δ 13 C values of the samples were determined with an isotope ratio mass spectrometer (Delta Plus, Finnigan MAT GmbH, Bremen, Germany).…”

Considering the close connection between soil microorganisms with carbon (C) cycling, the aim of this study was to identify the specific bacterial and fungal microbes that assimilate 13C from incorporated rice straw and explore their dynamics and characteristics during straw decomposition in paddy soil. Soil microcosms based on 12/13C‐labeled rice straw were incubated with the determination of CO2 production at 1, 3, 7, 14, 28, 56 and 90 days after straw incorporation. Meanwhile, the targeted soil bacterial and fungal communities were characterized using a DNA‐based stable isotope probing (DNA‐SIP) approach combined with Illumina MiSeq sequencing. Rice straw decomposed rapidly in the first 2 weeks, coupled with a large turnover of soil native organic matter. During this process, Actinobacteria including the orders Streptomycetales, Caternulisporales and Corynebacteriales dominated the community utilizing rice straw‐derived C with a succession from Streptomyces, to Kitasatospora, to Catenulispora. At Days 56 to 90, the dominant orders assimilating rice straw‐derived 13C were Micrococcales, Sphingobacteriia, Gammaproteobacteria from phyla Actinobacteria, Bacteroidetes and Proteobacteria, respectively. The fungal orders Onygenales, Capnodiales, Sordariales and Pleosporales showed stronger ability of 13C utilization at late decomposition stage. Taken together, along with stimulation of soil organic matter mineralization after rice straw addition, dynamics of 13C‐assimilating bacterial and fungal groups with various characteristics were identified.

“…The application of straw to soil has received great attention because of its potential benefits such as fertility improvement and carbon (C) sequestration. Straw amendment significantly increased respiration rate, total phospholipid fatty acids (PLFAs) and 13 C-PLFA especially actinomycetes, Gram-positive bacteria and fungi (Pan et al 2016). Microbial diversity and their populations are the important factors that govern the enzyme activities in soil.…”

This study analysed the effectiveness of innovative (basalt meal, brown algae extract) and conventional (barley straw) substances which hypothetically alleviate the inhibiting effect of Cd2+ on biochemical properties of soil, with particular regard to the activity of arylsulfatase. An analysis of their potential was carried out based on the activity of arylsulfatase and the number of Pseudomonas sp. determined on the 25th and 50th days of the study. Cd2+ was applied in the following doses: 0, 4, 40, 80, 120, 160, 200 mg Cd2+ kg−1 of DM soil, in the form of CdCl2·2.5H2O. A complex formulation of the issue was obtained from the presentation of biochemical properties using the RS (resistance of soil) index. Cadmium caused permanent adverse effects in the soil environment, inhibiting the activity of arylsulfatase and the yield of spring barley. The consequences of stress connected with increasing Cd2+ pollution were intensified by an elongation of the accumulation time of the tested metal in the soil. Chances for regeneration of the soil may be sought, most of all, with the application of straw and, to a lesser degree, with basalt meal. Brown algae did not meet the expectations for its potential. An increase in the studied parameters also resulted from sowing the soil with spring barley.

“…It promotes an increase in the cation exchange capacity (CEC) and availability of nutrients to the soil, resulting in improvements in soil fertility (Lima et al, 2015). In the soil biological conditions, biochar acts by influencing the composition, diversity and microbial activity of the soil (Doan et al, 2014;Purakayastha et al, 2015;Wang et al, 2015;Pan et al, 2016).…”

Biochar has attracted the attention of the scientific community due to its promising applicability and contribution to the elevation of soil chemical and biological aspects, directly influencing the microbiota, fertility levels and yield of agricultural crops. The objective of this study is to determine the chemical and biological attributes of an acrisol cultivated with beans and submitted to the application of ouricuri biochar. The design was completely randomized in a 4 × 4 factorial scheme, with 4 replications. The factors were the combination of four granulometric bands: G1 (0.42 mm), G2 (0.84 mm), G3 (1.19 mm), G4 (1.68 mm) and four biochar doses (8, 16, 24 and 32 Mg ha -1 ). Then, a control treatment without biochar was added. Morphophysiological aspects of bean culture, and chemical and biological soil indicators were evaluated. Ouricuri biochar promoted improvements in some soil quality indicators. The dose of 32 Mg ha -1 of biochar positively influenced the vegetative development of the plants. The results of this study showed that there is a direct relationship between the particle size and the amount of biochar in the soil. This had a direct effect on the carbon stock of the soil and the microbial population.
