“…However, increasing production costs, exhaustion of mineral sources, consumption of energy, environmental risks, destroying the soil structure and breaking the soil's microecosystem, and groundwater pollution are the problems associated with the excess use of chemical fertilizers [5]. An important alternative soil management to reduce the harmful effects of chemical fertilizers is the use of biological approaches, such biofertilizers [6]. Improving soil fertility, soil bacterial diversity, water and nutrient uptake, and plant tolerance to stress promotes plant growth, and subsequently, increasing crop production is the advantage of biofertilizer application [7][8][9].…”

The indiscriminate use of hazardous chemical fertilizers can be reduced by applying eco-friendly smart farming technologies, such as biofertilizers. The effects of five different types of plant growth-promoting rhizobacteria (PGPR), including Fla-wheat (F), Barvar-2 (B), Nitroxin (N1), Nitrokara (N2), and SWRI, and their integration with chemical fertilizers (50% and/or 100% need-based N, P, and Zn) on the quantitative and qualitative traits of a rainfed wheat cultivar were investigated. Field experiments, in the form of randomized complete block design (RCBD) with four replications, were conducted at the Qamloo Dryland Agricultural Research Station in Kurdistan Province, Iran, in three cropping seasons (2016–2017, 2017–2018, and 2018–2019). All the investigated characteristics of rainfed wheat were significantly affected by the integrated application of PGPR chemical fertilizers. The grain yield of treated plants with F, B, N1, and N2 PGPR plus 50% of need-based chemical fertilizers was increased by 28%, 28%, 37%, and 33%, respectively, compared with the noninoculated control. Compared with the noninoculated control, the grain protein content was increased by 0.54%, 0.88%, and 0.34% through the integrated application of F, N1, and N2 PGPR plus 50% of need-based chemical fertilizers, respectively. A combination of Nitroxin PGPR and 100% of need-based chemical fertilizers was the best treatment to increase the grain yield (56%) and grain protein content (1%) of the Azar-2 rainfed wheat cultivar. The results of this 3-year field study showed that the integrated nutrient management of PGPR-need-based N, P, and Zn chemical fertilizers can be considered a crop management tactic to increase the yield and quality of rainfed wheat and reduce chemical fertilization and subsequent environmental pollution and could be useful in terms of sustainable rainfed crop production.

The biochar properties, such as high porosity and adsorption capacity, have also been suggested as favorable in the development of an N-carrier for sustainable agriculture (Chen et al 2019a, b;Sun et al 2021). The use of biochar-based N fertilizers (BBNFs) has been considered among the most effective strategy for reducing N loss and improving NUE (Liu et al 2019;Chen et al 2019a, b;Dong et al 2020).…”

Globally, nitrogen (N) fertilizer demand is expected to reach 112 million tonnes to support food production for about 8 billion people. However, more than half of the N fertilizer is lost to the environment with impacts on air, water and soil quality, and biodiversity. Importantly, N loss to the environment contributes to greenhouse gas emissions and climate change. Nevertheless, where N fertilizer application is limited, severe depletion of soil fertility has become a major constraint to sustainable agriculture. To address the issues of low fertilizer N use efficiency (NUE), biochar-based N fertilizers (BBNFs) have been developed to reduce off-site loss and maximize crop N uptake. These products are generally made through physical mixing of biochar and N fertilizer or via coating chemical N fertilizers such as prilled urea with biochar. This review aims to describe the manufacturing processes of BBNFs, and to critically assess the effects of the products on soil properties, crop yield and N loss pathways. Graphical Abstract

“…On the other hand, new and labile organic matter can increase the biomass and activity of microbial in soil and speed up the mineralization of nitrogen elements, which causes the increase of nitrogen content [23]. Sun et al [24] reported that biofertilizer and biochar addition could provide available energy sources to soil microorganisms to stimulate denitrification and enhance N 2 O emission, which reduces the content of alkali-hydrolyzable nitrogen. Because of the short experimental environment and time, the bamboo charcoal used was fresh, and the effect of the bamboo charcoal on soil improvement had not been fully revealed, the effect of bamboo charcoal application on available K was not significant.…”

Soil heavy metal pollution is becoming more and more serious. Biomass charcoal application can play an important role in alleviating the toxicity of heavy metals in soils. Compared with other biochar, bamboo charcoal has more unique properties and may have a unique effect on heavy metal pollution. Zhejiang Province of Southeastern China is rich in bamboo resources. However, few studies related to bamboo charcoal application for heavy metal remediation in farmland were reported. In this study, four treatments with different amounts of bamboo charcoal application were set up through a field experiment, namely BC0 (no bamboo charcoal application), BC1 (2500 kg⋅ha −1 ), BC2 (5000 kg⋅ha −1 ), and BC3 (10000 kg⋅ha −1 ), and each treatment was replicated three times. The results showed that (1) The application of bamboo charcoal significantly increased the soil pH and organic matter content. Compared with BC0, the pH and organic content of BC3 increased by 7.4% and 17.4% (P < 0.05) respectively. (2) The HCl-extractable Cd content of paddy soil in the BC1 treatment was significantly lower than other treatments (P < 0.05), and decreased by 15.3%, compared with BC0. The soil HCl-extractable Zn and Cu content did not differ significantly between treatments (P > 0.05). ( 3) With the increase of bamboo charcoal application, the Cd content in rice gradually decreased, the BC3 treatment significantly decreased by 39.0% (P < 0.05), and the Zn and Cu contents in rice did not differ significantly between treatments (P > 0.05), compared with BC0. (4) Soil pH, organic matter and Cd in rice seeds were significantly negatively correlated (P < 0.01). The heavy metal content in rice does not change with the change of heavy metal content with HCl-extractable state in soil. It means bamboo charcoal does not reduce heavy metal content in rice by simply declining the heavy metal content with HCl-extractable state. The mechanism of action is relatively complicated, and further study is needed.
