“…Depending on different kinds of soil disturbances or stresses, the extent of the effect of soil land-use type on crop productivity may also vary [68,69]. However, the availability and use of mineral nutrients (such as P, K, Fe, Mn, Zn, and Cu) by plants can be enhanced by using biochar, as well as their tolerance to salinity stress being supported [70]. Calcium absorption in the growing medium is reduced under salinity stress circumstances, probably due to an osmotic problem.…”

The natural environment of crops is exposed to a complex collection of biotic and abiotic pressures. Abiotic stresses cover a diversity of environmental elements that cannot be avoided, such as temperature, drought, salinity, cold, heat, light, and water stress. Biotic stress is caused by living organisms with which plants coexist and interact. Pathogens and herbivores are examples of biotic stressors that can threaten food security and result in significant economic losses. Agricultural production systems differ in the extent of stress towards cultivated crops; agroforestry is considered to provide a protective function against environmental stress. The concept of this review was to assess the impact of environmental change and the atmospheric variability on the plants in agroforestry systems. The application of trees in field crop production has become more and more involved in practice, especially in areas with an extreme climate and unfavorable soil conditions. The main reasons for the rising interest are the effects of climate change, soil degradation, and erosion. Most of the trees are used as hedgerows or farm boundaries, or as scattered planting on the farm to control soil erosion as well as to improve farm productivity, which requires a thorough understanding of each stress element.

“…These results indicate that lettuce plans responded by lowered synthesis of carotenoids to restricted availability of nutrients in the substrates amended with SS + Z-biochars, similar to chlorophylls. Ghassemi-Golezani et al [96] also described the decrease of photosynthetic pigments such as chlorophylls and carotenoids in safflower (Carthamus tinctorius L.) leaves in the case of salt toxicity of soil [96], but the application of biochar and particularly biocharbased nanocomposites of magnesium and manganese oxides reduced sodium accumulation and improved biosynthesis of photosynthetic pigments.…”

Background Sewage sludge (SS) has been considered a potent source of soil nutrients. However, its direct application to agricultural soils have been discouraged owing to its toxic nature. Therefore, conversion and modification of SS to decrease its toxicity has resulted in advanced methods. Co-pyrolysis of SS with other amendments is an ideal treatment resulting in an environmentally safe and nutrient rich final products with additional properties to sequester carbon. In the present study, a novel biochar was produced through the microwave pyrolysis of SS mixed with zeolite and sawdust. The pyrolysis product was thus characterized for elemental composition, polycyclic aromatic hydrocarbons, via Fourier Transform Infrared Spectroscopy (FTIR), and for its effects on soil microbial characteristics, soil health and plant biomass after soil application. Results Results revealed that, the SS modification resulted in stable product with higher nutrients which further depend on the type and ratio of feedstock used. Its application to soil significantly improved soil chemical and microbiological properties and altered lettuce biomass. Conclusions We concluded that sawdust feedstock promoted nutrient availability in the resulting biochar and induced higher activity of nutrient mineralizing enzymes, whereas zeolite slowed down the release of nutrients from soil and putatively immobilized enzymes. This joint effect of sewage sludge biochar, sawdust and zeolite benefited the plant acquisition of nutrients in comparison with the microbial nutrient uptake. We thus conclude that microwave pyrolyzed SS could be used as a soil enhancer. Graphical Abstract

“…As a result of osmotic and oxidative stresses, a high level of reactive oxygen species (ROS) that can damage nucleic acids and proteins can be generated (Farhangi‐Abriz & Nikpour‐Rashidabad, 2017; Napieraj et al, 2020). Metal oxide–biochar nano‐composites have proven effective in aiding the salinity adaptation of safflower (Ghassemi‐Golezani et al, 2020). Because of their high pore volumes, specific surface areas and CECs, both MgO– and MnO–biochar nano‐composites adsorb sodium effectively, thus reducing sodium uptake by plants.…”

“…Furthermore, magnesium and manganese are closely related to chlorophyll generation (Peng et al, 2019; Sun et al, 2001). Increased content of photosynthetic pigments after the application of these composites can also diminish the oxidative stress caused by salt toxicity (Ghassemi‐Golezani et al, 2020).…”

Engineered biochars are promising candidates in a wide range of environmental applications, including soil fertility improvement, contaminant immobilization, wastewater treatment and in situ carbon sequestration. This review provides a systematic classification of these novel biochar composites and identifies the promising future trends in composite research and application. It is proposed that metals, minerals, layered double hydroxides, carbonaceous nanomaterials and microorganisms enhance the performances of biochars via distinct mechanisms. In this review, four novel trends are identified and assessed critically. Firstly, facile synthesis methods, in particular ball milling and co‐pyrolysis, have emerged as popular composite fabrication strategies that are suitable for large‐scale applications. Secondly, biochar modification with green materials, such as natural clay minerals and microorganisms, align well with the on‐going green and sustainable remediation (GSR) movement. Furthermore, new applications in soil health improvement and climate change mitigation support the realization of United Nation's Sustainable Development Goals (SDGs). Finally, the importance of field studies is getting more attention, since evidence of field success is critically needed before large‐scale applications.
