“…Biochar has recently been suggested as a possible alternative for mitigating the impact of salinity on crop growth and development (Thomas et al 2013;Akhtar et al 2015;She et al 2018;Farhangi-Abriz and Torabian, 2018;Huang et al 2019;Rezaie et al 2019;Ibrahim et al 2020;Xiao et al 2020). However, both biochars used in this study exhibited contrasting effects on most measured plant-related parameters, and none revealed clear effects in alleviating the impact of salinity stress relative to the control (0 dS m -1 and BC0 treatment).…”

“…Overall, most studies reported that biochar improved the plant germination rate and growth characteristics under saline conditions (e.g. Thomas et al 2013;Akhtar et al 2015;She et al 2018;Farhangi-Abriz and Torabian, 2018;Huang et al 2019;Rezaie et al 2019;Ibrahim et al 2020;Xiao et al 2020). Besides feedstock type, pyrolysis temperature is another major factor that largely influences the physical and chemical properties of biochar, and thereby its performance as a soil amendment and its other uses, including salinity stress mitigation Tomczyk et al 2020).…”

“…However, the magnitude of biochar effect in reducing salinity stress on plant growth and development widely vary, which depend on salinity level, biochar characteristics, soil type, and species (Thomas et al 2013;Dahlawi et al 2018;Xiao et al 2020;Tan et al 2021). Further studies are required to verify the potential use of biochar in alleviating the adverse effect of salinity on plant growth, especially under arid soil conditions, where several productivity constraints exist, such as alkalinity, high content of CaCO 3, and poor content of organic matter and nutrient.…”

Tremendous benefits of biochar (BC) amendment to soil have been reported, including their role in alleviating the impact of salinity stress in plants. The aim of this study was to evaluate the effects of BC produced at 300 ºC (BC300) and 700 ºC (BC700) on the germination rate (GR) and selected growth characteristics of corn plant irrigated with salinized water over a growth period of six weeks. The experimental treatments included: three biochar treatments [BC0 (control, without biocar addition), BC300 and BC700] and three salinity levels of irrigation water [0, 3, and 6 dS m-1]. The biochar was applied at a rate of 3%. The GR decreased with increasing salinity level, which was more evident in the first week. This stress impact was reduced when treated with the BC700 relative to the saline treatments without BC. Both BCs demonstrated contrasting effects on corn growth, nutrient uptake, and Na+ and K+ content in plant tissue. The effect of BC700 treatment on plant height and root length was limited, but the impact of salinity stress on chlorophyll meter readings, chlorophyll fluorescence parameter (Fv/Fm), dry matter yield, and N and P uptake were largely mitigated. It also increased K+ and decreased Na+ content in plant tissue. However, the BC300 treatment adversely affected plant growth parameters at each salinity level. Overall, the BC produced at a higher temperature significantly alleviated the impact of salinity stress on plant growth characteristics, which is probably attributed to their higher surface area and porosity, enhancing their salt ion sorption capacity.

Coastal soils in the Yellow River Delta (YRD) are characterized by high salinity and degraded physicochemical properties, which threaten agricultural production. Biochar has received growing interest as a sustainable soil amendment. However, the effects of biochar on coastal soil quality and the soil microbial response in the field are limited. In this study, the responses of soil properties and microbes to biochar amendment at low dosage (LBC, 18 ton/ha) and high dosage (HBC, 36 ton/ha) and no biochar treatment (CK) were investigated in a peanut field located in the YRD. The results elucidated that biochar-amended soils showed higher available nutrient (i.e., nitrogen, phosphorus, and potassium) contents and cation exchange capacity, but exhibited lower electrical conductivity. Generally, the bacterial community was more easily impacted than that of fungi in both LBC and HBC treatments. Furthermore, the LBC amendment not only improved the abundance of some beneficial bacteria (i.e., Sphingomonas and Nannocystis) but also increased the complexity, modularity index, and competitive interactions of the bacterial co-occurrence network. HBC-enriched Rozellomycota that is probably associated with peanut rot decreased the modularity index and competitive interactions, which might account for the decreased peanut yield under HBC treatment. It is encouraged to comprehensively consider the interaction among microorganisms when evaluating the effects of soil amendments on the soil environment, which plays a vital role in rhizosphere microecology and soil quality.

“…Coastal soils are important reserve land resources for food production; however, there is an area of 3.4-9.8 billion m 2 of them degrading every year worldwide [1,2]. Coastal soils face a series of problems, including high pH value and salinity, low water and nutrient retention capacity, poor air and water permeability, and low soil organic carbon concentrations [3][4][5]. These problems restricted the sustainable development of agriculture and food safety [6].…”

Biochar Enhanced Growth and Biological Nitrogen Fixation of Wild Soybean (Glycine max subsp. soja Siebold & Zucc.) in a Coastal Soil of China

The high salinity and nutrient deficiency in degraded coastal soil restricts crop growth and grain production. The development of effective and novel technology for coastal soil remediation is of great requirement. The effect of wood waste biochar (WB) on the growth and biological nitrogen fixation of wild soybean (Glycine max subsp. soja Siebold & Zucc.), a legume with high economic values and salt tolerance in coastal soil, were explored using a 42-day pot experiment. With the optimal rate of WB addition (1.5%, w/w), the biomass and plant height of wild soybean increased by 55.9% and 28.3%, respectively. WB addition enhanced the photosynthesis (chlorophyll content) and biological nitrogen fixation (nodule number) of the wild soybean. These results may attribute to the improvement of the soil properties including the SOM, NO3−-N content, and WHC. In addition, the shifted bacterial community following WB addition in the coastal soil favored the nitrogen fixation of wild soybean, which was evidenced by the increased abundance of nifH gene and Pseudarthrobacter, Azospirillum, and Rhizobiales. The results of our study suggested the potential of using biochar-based technology to reclaim the coastal degraded soils and enhance the crop growth to ensure food security.
