“…The microbial biomass carbon and nitrogen were extracted by the chloroform fumigation method and 0.5 mol/L K 2 SO 4 extraction method, where the conversion coefficients were 0.45 and 5, respectively ( Jien and Wang, 2013 ; Khan et al, 2020 ). The urease activity was determined by the indophenol blue colorimetric method ( Yang et al, 2017 ), The activity of urease was defined as milligrams of ammonia nitrogen relieved per Gram of soil in 24 h. Catalase activity was measured by the KMnO 4 titration method ( Yin et al, 2014 ); sucrase activity was measured by reducing sugar titration method ( Guan et al, 1986 ); and soil phosphatase activity was measured by disodium p -nitrophenyl phosphate colorimetry method ( Guan et al, 1986 ).…”

“…This strategy becomes an important way to eliminate fecal pollution and realize the harmless utilization of feces in the large-scale livestock and poultry industry ( Crane-Droesch et al, 2013 ). With a further application of these biochars as soil amendments, the soil fertilities can be improved due to the increased soil nutrient availability, soil organic matter content, and improved physical and biochemical characteristics of the soil ( Jien and Wang, 2013 ; Khan et al, 2020 ). Therefore, the studies of the effects of swine-manure biochar on the tea garden soil functions are of great significance to improve tea garden soil qualities, which would in turn promote tea qualities.…”

Animal-manure biochar used as a sustainable amendment to garden soil has been widely applied, and the animal-manure pyrolysis temperatures would also have a regulatory effect on soil functions because of their affections on biochar physio-chemical properties. Here we studied the effects of different dosages of swine-manure biochar on tea garden soil functions, with the swine-manure pyrolysis temperature differed at 350 and 500°C. The results showed that the improvement of soil microbial biomass carbon and nitrogen and enzyme activities was closely related to the addition of 0.5–2% (biochar wt/soil wt) swine-manure biochar. Under different conditions of different carbon application rates and carbon type, the addition of 2% swine-manure biochar pyrolyzed at 350°C showed the best effects on soil enzyme activities and microbial biomass carbon and nitrogen contents. Compared to the control, after the addition of 2% swine-manure biochar, sucrase, phosphatase, catalase, and urease activities increased by 63.3, 23.2, 50.3, and 27.9%, respectively. Microbial biomass carbon and nitrogen contents also increased by 36.4 and 34.3%, respectively. Our study indicated that the effectiveness of using animal-manure swine-manure biochar as a sustainable amendment to soil would provide evidence of tea garden soil improvement and the environmental response to the usage of biochars.

“…The reason for the increase in the weighted diameter rate may be attributed to Table (1)When charcoal is added to the formation of hard materials when decomposed by microbial activity and the release of organic acids that help stabilize aggregates such asFulvic acid and polysaccharides that play an important role along withnegativesMultiple shipmentsCa+2 and Mg+2, which together contribute to increasing the stability of the aggregates and thus increasing the weighted diameter ratio [13], and attributed [4]. The role of biochar in increasing the average weighted diameter of the soil indicates that the organic matter resulting from decomposition coagulates clay suspensions, which leads to the binding of soil particles to aggregates, whilepointed out [15].…”

BackgroundBiochar can enhance phytoremediation in petroleum hydrocarbon polluted soils, making it an intriguing soil amendment option for remediating polluted soil. Biochar can improve the fertility of depleted soils through a range of mechanisms. This study can contribute valuable insights into the origin of biochar and enhance our understanding of the efficacy of different biochar types in remediating petroleum hydrocarbon polluted soils.AimsTo assess the efficacy of different biochar types and plant growth in remediating petroleum hydrocarbon polluted soils.MethodsA field experiment was conducted at the automobile workshop (commonly called mechanic village) from July to October 2021, using a randomized complete block design. The land was sectioned into designated plots with three replicates. Maize stalk biochar (MSB) and nipa palm biochar (NPB) were treated differently in each plot at a rate of 20 t ha−1. Plots containing no biochar were used as controls. Initial and final soil analyses were conducted.ResultsPreliminary soil assessments revealed higher values of soil bulk density (1.51 g cm−3), moisture content (35.02%), organic carbon (41.01 g kg−1), cation exchange capacity (13.27 cmol kg−1), total petroleum hydrocarbon content (PHCt) (775.83 mg kg−1), cadmium (Cd) (5.41 mg kg−1), chromium (Cr) (25 mg kg−1), lead (Pb) (33.51 mg kg−1), and zinc (Zn) (0.91 mg kg−1) in the polluted soil than in the unpolluted counterpart. The polluted soil displayed lower hydraulic conductivity (Ks) (1.17 cm h−1), available phosphorus (69.46 mg kg−1), manganese (Mn) (6.38 mg kg−1) and iron (Fe) (4.18 mg kg−1) contents than the unpolluted soil. The PHCt, Cd, and Cr were significantly decreased following the application of biochar. NPB recorded the lowest petroleum hydrocarbon (19%), lead (37%), manganese (57%), and zinc (69%) contents, whereas MSB had the lowest cadmium (50%) and chromium (27%) contents when compared with the control. Between heavy metal accumulations in the leaves and fruits, a greater accumulation of Cd, Cr, and Pb was found in the leaves, whereas Ni accumulation was found in the fruits. The highest Cd (47.0 mg kg−1) and Ni (8.3 mg kg−1) accumulations in the leaves were recorded in NPB treated plots. Similarly, Cd (5.3 mg kg−1), Cr (3.7 mg kg−1), Pb (21.6 mg kg−1), and Ni (23.4 mg kg−1) accumulation in the fruits recorded the highest values in the NPB treated plots. The NPB plants were the tallest compared with the other treatments. In addition, NPB plants had the widest leaf area compared with other treatments.ConclusionThe results indicated that the amendment of NPB may be suitable for the phytoremediation of soils polluted with petroleum hydrocarbons.
