“…In addition, Jeffery et al (2011) in a meta-analysis indicated biochar-treated soils increased crop productivity averagely at 10% (-28% to 39%) compared with plots without mulching. Residual impact of biochar on soil fertility largely accounted for an increase in crop yield under co-application of plastic film mulched ridge-furrow with biochar treatment (Rehman & Razzaq, 2017).…”

Background China is the leading consumer of plastic film worldwide. Plastic film mulched ridge-furrow is one of the most widely adopted agronomic and field management practices in rain-fed agriculture in dry-land areas of China. The efficiency of plastic film mulching as a viable method to decrease evapotranspiration (ET), increase crop yields, and water use efficiency (WUE), has been demonstrated extensively by earlier studies. Methods A comprehensive evaluation of how co-application of plastic-film mulch and biochar in different agro-environments under varying climatic conditions influence ET, crop yield, WUE, and soil microbial activity were assessed. We performed a meta-analysis using the PRISMA guideline to assess the effect of plastic-film mulched ridge-furrow and biochar on ET, yield, and WUE of wheat (Triticum aestivum L.), potato (Solanum tuberosum L.), and maize (Zea mays L.) in northern China. Results The use of plastic film increased average yields of wheat (75.7%), potato (20.2%), and maize (12.9%) in Gansu, Ningxia, Shaanxi, and Shanxi provinces, respectively due to the reduction in ET by 12.8% in Gansu, 0.5% in Ningxia, and 4.1% in Shanxi, but increased in Shaanxi by 0.5% compared to no-mulching. These changes may be attributed to the effect of plastic film mulch application which simultaneously increased WUE by 68.5% in Gansu, 23.9% in Ningxia, 16.2% in Shaanxi, and 12.8% in Shanxi, respectively. Compared to flat planting without mulching, in three years, the yield of maize increased with the co-application of plastic film and biochar by 22.86% in the Shanxi and Shaanxi regions. Conclusion Our analysis revealed co-application of plastic film with biochar is integral for improving soil and water conservation in rain-fed agriculture and as an integrated practice to avert drought while simultaneously mitigating runoff and erosion.

“…Nowadays, agricultural residues with high carbon content, such as palm shell, coconut coir, and rice husk have been studied as potential alternative adsorbents for AC (Sun et al, 2013;Ahmad et al, 2014;Mook et al, 2016;Mi et al, 2016). Typically, they can be applied to produce biochar by thermal degradation in oxygen-limited conditions, and consequently utilized as a low-cost adsorbent for pollutant separation from air, or heavy metals as well as textile dye removal from wastewater (Mi et al, 2016;Moazzam et al, 2017;Rehman and Razzaq, 2017). Biochar adsorption has been intensively studied because it has excellent adsorption capability and satisfies the need for cost effective adsorbents.…”

A solid agricultural waste, coffee husk, was applied as an adsorbent for reactive dye-polluted wastewater treatment. Coffee husk biochar was pyrolyzed at 450 °C and then chemically activated using 50% ZnCl2 solution. The surface of activated coffee husk biochar was modified using a cationic surfactant, Cetyltrimethylammonium bromide (CTAB), to create CTAB-modified coffee husk biochar (MCH), to improve reactive adsorption of anionic dyes from synthetic wastewater. The selected reactive dyes were reactive yellow 145 (RDY145), reactive red 195 (RDR195), and reactive blue 222 (RDB222). The adsorption kinetics fit well using a pseudo-second order model for all three dyes. The adsorption isotherms matched well with the Langmuir model .The removal efficiency of RDY145 (83.7%) was the highest, followed by RDR195 (71.1%) and RDB222 (59.6%). The amount of RDY145 adsorbed by MCH was about 9-fold that adsorbed by conventional activated carbon. Additionally, the solution pH had no effect on reactive dye removal efficiency using MCH.

“…It can be used to enhance degraded soils so that they can be utilized for agricultural production that helps mitigate the effects of climate change (Lehmann & Joseph, ). Many studies have shown the beneficial effects of biochar on soil properties such as pH (Masulili, Utomo, & Syechfani, ), nutrient availability (Chan, Van Zwieten, Meszaros, Downie, & Joseph, ), nutrient retention, microbial properties (Rehman & Razzaq, ), and hydrological properties (Sandhu & Kumar, ). Due to its higher surface area and pore space, biochar provides habitat for soil microbes that are beneficial for soil health and helps in nutrient retention by binding important anions and cations (Rehman & Razzaq, ).…”

Biochar and manure application can modify soil microbial community structure and enhance biochemical activities. However, the studies about the influence of biochar and manure on the microbial communities on different geomorphological landforms (depositional and eroded landscapes) are scarce. In this study, we investigated the responses of soil biochemical activities and microbial communities to the addition of pinewood biochar, dairy manure (DM), and the dairy manure and pinewood biochar mixture (DMP) at a rate of 10 Mg ha−1, respectively, in comparison with control (CNT) at eroded and depositional landscape positions over 5 years. Data showed that the DMP treatment significantly increased cold‐water‐soluble organic carbon and hot‐water‐soluble organic carbon at the depositional landscape than CNT soils. Application of DMP increased total phospholipid fatty acid (PLFA) and bacterial PLFA by 31% and 20% compared with the CNT at the depositional landscape, respectively. At eroded landscape, total PLFAs and total bacterial PLFAs biomass concentrations were found 39% and 90% higher with DM than CNT soils. The addition of DM and DMP increased the activities of enzymes that are involved in the major nutrient cycling at depositional and eroded landscapes. At the phylum level, the proportion of Bacteroidetes was found lower in DMP, but the proportion of phylum Proteobacteria and Acidobacteria were increased. In conclusion, our study revealed that DMP influenced the labile nutrient pool, altered the microbial community structure, and increased bacterial composition and enzymatic activities at both the landscape positions.
