“…This suggests that the addition of acidified rice husk can increase the content of nitrogen in soil and reduce nitrate leaching loss and N 2 O emission. These findings are consistent with those of previous studies [72][73][74]. In contrast, the single application of mushroom bran promoted ANRA, DNRA, denitrification, and complete nitrification.…”

Soil improvement methods can result in changes in the microbial community in blueberry soil. Bacterial communities play an important role in soil fertilizer and plant nutrient acquisition. In this study, the response of microbial community composition, microbial function, and the nitrogen (N) cycle to different improvement methods was analyzed using high-throughput sequencing to investigate the best soil improvement method from a microbial perspective. The results showed that the highest microbial diversity was observed in the treatment involving peat combined with mushroom bran (T2), followed by the peat combined with acidified rice husk (T2) both in the rhizosphere and roots. The dominant phyla were Proteobacteria and Actinobacteria both in the blueberry rhizosphere soil and roots. Interestingly, Acidobacterium and Paludibaculum, belonging to the Acidobacteria phylum, exhibited the most significant influence and were most predominant in the T2 treatment rhizosphere soil. The T2 treatment promoted the growth of N fixation functional bacteria both in the rhizosphere soil and roots. At the module level, the T2 treatment enhanced N fixation and suppressed the assimilatory and dissimilatory nitrate reduction reactions, denitrification, and nitrification in the blueberry rhizosphere. Additionally, the T2 treatment increased the abundance of root endophytic microbes involved in N fixation. Overall, our findings suggest that the addition of peat combined with acidified rice husk is the optimal soil improvement method for blueberry cultivation.

The article analyzes the use of biochar in various industries and the national economy (as a sorbent, fuel, reducing agent in the metallurgical industry, a component of coal coke blends, biocomposites, modification of explosives, fertilizers, etc.) It is noted that the direction of use depends on the quality and characteristics of biochar (size, physical properties, chemical composition), which are determined by the nature of the raw material, its chemical composition and carbonization temperature.

Global concern over climate change, driven by greenhouse gas emissions, has prompted widespread interest in sustainable solutions. In the agricultural sector, biochar has emerged as a focal point for mitigating these emissions. This study investigated the impact of continuous biochar application on CO 2 and N 2 O emissions during the spring cabbage cultivation period. Greenhouse gas emissions in the biochar treatment groups (soils treated with 1, 3, and 5 tons/ha of rice husk biochar) were compared to those in the control group without biochar. During the spring cabbage cultivation period in 2022, the total CO 2 emissions were in the range of 71.6-119.0 g/m 2 day, and in 2023, with continuous biochar application, they were in the range of 71.6-102.1 g/m 2 day. The total emissions of N 2 O in 2022 and 2023 were in the range of 11.7-23.7 and 7.8-19.9 g/m 2 day, respectively. Overall, greenhouse gas emissions decreased after biochar treatment, confirming the positive influence of biochar on mitigating greenhouse gas release from the soil. Nevertheless, further research over an extended period exceeding five years is deemed essential to delve into the specific mechanisms behind these observed changes and to assess the long-term sustainability of biochar's impact on greenhouse gas dynamics in agricultural settings.
