“…Basal respiration in the Valečov soil reached the average amount 1.32 in the control and 1.56, 1.32, 1.52 in biochar amendment samples at the rates of 0.5, 1 and 3%, respectively (amounts are given in mg CO 2 /h/100 g). In the Čistá soil, basal respira- Mitchel et al (2015) and Xu et al (2016) observed significantly higher respiration rates after biochar treatment; these results were found out after 5 months and 6 months. Rutigliano et al (2014) observed that the respiration rate increased in the first 3 months and was statistically significantly higher than control, but after 14 months there were no differences between samples.…”

ABSTRACTŠlapáková B., Jeřábková J., Voříšek K., Tejnecký V., Drábek O. (2018): The biochar effect on soil respiration and nitrification. Plant Soil Environ., 64: 114-119.Soil microorganisms play a main role in the nutrient cycle and they also play an important role in soil health. This article studies the influence of three rates of biochar (0.5, 1 and 3%) in comparison with control (0 biochar) in two different soils (Valečov and Čistá) on soil microbiota activities. The biochar was prepared from 80% of digestate from Zea mays L. and 20% of cellulose fibres by pyrolysis (470°C, 17 min). The biochar ability to influence microbial processes in soil was determined by respiration and nitrification tests. There were no significant differences between basal respiration of control samples and biochar-amended samples. Basal respiration in the Valečov soil reached average amounts from 1.32 to 1.52 mg CO 2 /h/100 g. In the Čistá soil, basal respiration reached average amounts from 1.40 to 1.49 mg CO 2 /h/100 g. No significant differences were proved also in nitrification tests of both soils. Nitrifying potential was the highest in 3% rate of biochar amendment. There were no negative changes in the measured soil parameters. CO 2 efflux was not higher in biochar-amended soil.

“…Moreover, modified biochar effectively reduced the risk of N leaching in the meadow cinnamon soils of northern China (Xu et al, 2016). On the other hand, research has also shown that biochar amendment accelerates the leaching of nitrite from soils (Eykelbosh et al, 2015).…”

“…Many studies that have suggested that biochar addition reduces the loss of NO 3 − -N via leaching or increases soil accumulation were conducted over relatively short incubation periods (days to months) (Novak et al, 2010;Angst et al, 2013;Eykelbosh, 2015;Xu et al, 2016) …”

“…For bacteria, the V3-V4 hypervariable regions of the bacteria 16S rRNA gene were amplified with primers 338F (5 0 -ACTCCTACGGGAGGCAGCAG-3 0 ) and 806R (5 0 -GGACTACHVGGGTWTCTAAT-3 0 ) by thermocycler polymerase chain reaction system (Xu, Tan, Wang, & Gai, 2016; GeneAmp 9700, ABI, USA). Fungal Internal Transcribed Spacer (ITS) Region 1 was amplified using ITS1F (5 0 -CTTGGTCATTTAGAGG AAGTAA-3 0 ) and ITS2 (5 0 -GCTGCGTTCTTCATCG ATGC-3 0 ) primer pair (Bokulich & Mills, 2013;Kerfahi, Tripathi, Dong, Go, & Adams, 2016).…”

The ecological consequences of converting tropical forests to rubber plantations on the soil microbial compositions and diversity remain unknown. By using an Illumina MiSeq sequencing analysis, we assessed the compositions and diversity of bacterial and fungal community in soils of rubber plantation (or rubber forest, RF), secondary tropical forest (STF), and tropical seasonal rainforest (TSR) in Xishuangbanna, southwest China. Our findings revealed that (a) for bacterial composition, Bacillaceae was the most dominant family (13.60%) in RF soil, while it only accounted for 4.13% in STF and 6.92% in TSR. For fungal composition, the largest family in soils of RF was Basidiomycota_unclassified. However, the largest family in STF and TSR was Russulaceae. (b) Number of operational taxonomic units, Chao index, and Shannon index of bacterial community in soil of RF were significantly higher than those of TSR and STF. However, these diversity indices of fungal community in RF were significantly lower than those of TSR and STF. (c) Soil pH and total phosphorus were very important drivers for bacterial community, whereas soil organic matter and total nitrogen were the most important factors for fungal community. (d) The microbial biomass carbon in RF was relative lower than those in STF and TSR, which suggested that the total microbial biomass decreased after forest conversion. To protect the total diversity of this region, the individual farmers should use herbicides as little as possible to reserve ground vegetation. And the government could outline a land-use policy that prohibits the cultivation in areas of natural vegetation.
