“…Soil chemical parameters such as pH, cation exchange capacity, organic matter, soil carbon sequestration, soil nutrient content, and soil biological properties were also found to be improved. These changes in soil physiochemical and biological characteristics enhance soil fertility, plant growth, and development (Murtaza et al, 2023, Yue et al, 2023, Nyambo et al, 2023, Védère et al, 2023.…”

The copious amounts of data generated through publications play a pivotal role in advancing Science, Technology, and Policy. Additionally, they provide valuable and detailed information on research topics, emerging thematic trends, and critical issues that demand increased focus and attention. Over the last few decades, biochar has produced an extensive body of high-quality papers and played a crucial part in achieving the long-term Sustainable Development Goals of the 2030 agenda of the United Nations about “Climate Change,” “Sustainable Agriculture,” “Environmental Sustainability,” “Zero Hunger,” “Human Wellbeing,” and “Circular Bioeconomy”. However, most of the research is on biochar that has been modified or functionalized using various chemical reagents or catalysts and reported widely in peer-reviewed, high-quality journals. No prior work analyzed the bibliometric data on aging biochar with (a)biotic processes. This study presents an innovative data-driven bibliometric analysis technique and paradigm for extracting the essence of the available peer-reviewed literature data to offer new perspectives on the research opportunities and potential of aged biochar for agro-environmental applications. The bibliometric data analysis indicates that aging biochar research for agro-environmental applications received attention, advanced, and resulted in 165 high-quality publications in reputed journals between 2011 and 2023. However, it is evident that there is still a considerable need for further attention in this area. The identification of the research trends/frontiers shows that biochar production effectively employs various biomass resources, aging with different (a)biotic factors, characterization, effects on global climate change, long-term carbon sequestration in soil, soil nutrient dynamics, restoration of multi-polluted soils and sediments, and plant growth all require continuous attention both now and in the future.

“…Irrigation water deficit stress is one of the vital issues in the agricultural sector, where it is one of the factors leading to plant physiological disorders via raising the production of reactive Oxygen Species (ROS) The use of water-absorbent substances e.g., compost, biochar, zeolite, natural polymer ...... etc. to increase the soil's ability to retain irrigation water may be an effective solution to meet the water requirements of the plant (Nadeem et al, 2017;Védère et…”

OW, people in Egypt are under the water poverty limit a long time ago due to climate change and the shortage of water resources. These conditions hamper agricultural development in Egypt. Thus, a practical solution must be undertaken for confronting the water scarcity that hindered agricultural development in Egypt. So, two field trials were executed to assess three water levels of full irrigation [8000 m 3 ha -1 as traditional full irrigation (TFI) treatment followed in the studied area (100% of TFI), 6000 m 3 ha -1 (75% of TFI) and 4000 m 3 ha -1 (50 % of TFI)] as main plots. While different soil conditioners [without (control), biochar (at rate of 24 Mg ha -1 ) and plant compost (at rate of 24 Mg ha -1 ) in addition to both of them as combined treatment (at rate of 12 Mg ha -1 for each conditioner),1.0 Mg ʺmega gramʺ=10 6 g i.e., metric ton] were evaluated as subplots. Also, the foliar application of glycerol and sorbitol (0.0 and 500 mM L -1 ) represented the sub-sub plots. Maize was used as an experimental plant. Findings illustrate that treatments of 75 and 50 % of TFI led to a raise in the enzymatic antioxidants production after 60 days from sowing. While both soil conditioners (either solely or in combination) and the sugar alcohols led to a decline the values of these enzymatic antioxidants. On the contrary, at the period of 90 days from sowing (growth advanced stage), the grown plants without the studied substances (soil conditioners and sugar alcohols) cannot continue producing these enzymatic antioxidants under water deficit treatments. Also, the deficit irrigation (75 and 50 % of TFI) caused a significant decline in the performance and productivity of maize compared to traditional irrigation (100 % of TFI). For example, the highest values of fresh weight (951.64 and 965.61 g plant -1 , for 1 st and 2 nd seasons, respectively), leaf area (620.25 and 628.56 cm 2 plant -1 , for 1 st and 2 nd seasons, respectively) and chlorophyll content (40.55 and 41.42 SPAD for 1 st and 2 nd seasons, respectively) were realized under traditional irrigation (100 % of TFI) followed by those values achieved under deficit irrigation treatment (75 % of TFI), while the lowest one was recorded with 50 % of TFI treatment. Regarding the soil conditioners effect, the compost and biochar either solely or in combination improved the plant performance and productivity compared to the corresponding plants grown without soil conditioners. The highest values of growth criteria and productivity were realized with the combined treatment of compost and biochar followed by compost alone then biochar alone and lately control. Concerning sugar alcohols, the sorbitol was the superior, while the glycerol came in the second order and lately control treatment. Generally, it can be concluded that a combination of compost and biochar may hold enough amounts of irrigation water and nutrients and release them as required by the maize plant, thus enhancing plant growth performance with the limited supply of irrigation water. Also, sugar alcohols h...

“…Pinto et al (2023) report no positive effect of biochar on sugar cane plant development, while biochar positively influenced soil bacteria. This outcome may be linked to two plausible factors: firstly, the nutritional status of the soil may have already been optimal for the crop (Seehausen et al, 2017;Védère et al, 2023); and secondly, nutrient availability in wider soil may not have reached the threshold sufficient to saturate nutrient retention within biochar structures (Farhangi-Abriz et al, 2021).…”

Intensive agricultural practices have accelerated soil organic carbon mineralization, compromising soil health and function. This study evaluated the efficacy of microgranular biochar (MicroCHAR) and powdered biochar as soil additives enhancing soil function, and pea, maize and wheat growth and yield. We carried out a series of experiments with degraded drought‐prone soils in greenhouse and field conditions, combining biochar addition with arbuscular mycorrhizal fungi (AMF). The combination of amendments variously impacted soil nutrient status; availability of extractable potassium (K) increased in all cases, whilst that of calcium (Ca) was reduced when AMF inoculation was applied alone but not in combination with biochar. MicroCHAR positively affected root biomass and pea P content compared with the control, but biochar did not enhance N or K. Crop yield was not significantly increased by MicroCHAR amendment. MicroCHAR enhanced the mycorrhization rate of crop roots by 260%, an effect seen in the greenhouse and field conditions. This study suggests that credible benefits in some crops can be gained by the application of MicroCHAR to some soils. Observed effects may be soil and crop specific; future study of optimal nutrient and microorganism coatings on microgranular biochar opens exciting avenues for the improvement of crop yields in degraded agricultural soils.
