“…CEC represents the bulk of cations associated to the biochar surface. The CEC of soil tended to increase effectively after the addition of biochar due to the presence of the functional group and negative charge on the surface of biochar [41]. The results were similar to the findings of Peng et al [38] who reported that RS-derived biochar significantly raised the pH value by 0.1 to 0.46 units in soil and increased the CEC of soil by 17%.…”

The current study is aimed at deriving biochar (BC) from rice straw (RS-BC) and waste bones (WB-BC), being wasted without adequate return at the expense of environmental degradation. The RS and WB feedstocks were pyrolyzed at 550 oC, and the potential of derived biochar as a slow nutrient releasing soil amendment was examined during the growth of ridge gourd. Proximate analysis of the prepared biochars showed significant improvement in ash content and fixed carbon as compared to their raw biomasses. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) analysis of RS-BC and WB-BC displayed a diverse range of functional groups viz. derivatives of cellulose and hydroxylapatite (HA); macro and microporosity; multiple nutrients. Application of RS-BC and WB-BC in potted soil alone and as biochar composite (RS-BC+WB-BC) at 5, 10 and 15% (w/w) and chemical fertilizer (CF) resulted in a significant increase in soil pH, electrical conductivity (ECe), cation exchange capacity (CEC) and water holding capacity (WHC) in exchange for growth and yield of ridge gourd. However, there were insignificant differences in the growth of plants in response to RS-BC, WB-BC alone and CF with biochar composite at 15% amendment. For giving insignificantly different growth results than CF, the prepared biochar composite showed outstanding potential as an organic fertilizer applicable in agrarian soils to elevate soil properties and yield of agricultural commodities.

“…It indicated that the appropriate concentration of biochar addition could enhance the accumulation of N and the fixation of C, and possibly accelerate the progress of plant life activities, resulting in the accumulation of more nutrients [ 50 ]. The reasons for this may be the addition of biochar directly affects the microbial activity in the rhizosphere of the moss crusts to promote the conversion of nitrogen and phosphorus, thereby increasing the nitrogen and phosphorus content of the moss crust, and finally the C: N: P stoichiometric ratio of the moss crust is changed, and the C content also increases [ 51 , 52 ]. Furthermore, several studies have shown that biochar not only increased the K concentration in soil but also increased the plant nutrient use efficiency of K, which is important for plant growth.…”

The biogeochemical cycling of soil elements in ecosystems has changed under global changes, including nutrients essential for plant growth. The application of biochar can improve the utilization of soil nutrients by plants and change the stoichiometry of carbon (C), nitrogen (N), and phosphorus (P) in plants and soil. However, the response of ecological stoichiometry in a moss crust-soil continuum to local plant biochar addition in a desert ecosystem has not been comprehensively explored. Here, we conducted a four-level Seriphidium terrae-albae biochar addition experiment (CK, 0 t ha−1; T1, 3.185 t ha−1; T2, 6.37 t ha−1; T3, 12.74 t ha−1) to elucidate the influence of biochar input on C: N: P stoichiometry in moss crusts (surface) and their underlying soil (subsurface). The results showed that biochar addition significantly affected the C, N, and P both of moss crusts and their underlying soil (p < 0.001). Biochar addition increased soil C, N, and P concentrations, and the soil N content showed a monthly trend in T3. The C, N, and P concentrations of moss crusts increased with the addition levels of biochar, and the moss crust P concentrations showed an overall increasing trend by the month. Moreover, the soil and moss crust C: P and N: P ratios both increased. There was a significant correlation between moss crust C, N, and P and soil C and N. Additionally, nitrate nitrogen (NO3−N), N: P, C: P, EC, pH, soil moisture content (SMC), and N have significant effects on the C, N, and P of moss crusts in turn. This study revealed the contribution of biochar to the nutrient cycle of desert system plants and their underlying soil from the perspective of stoichiometric characteristics, which is a supplement to the theory of plant soil nutrition in desert ecosystems.

“…A meta-analysis conducted by Li et al (2020) has concluded that biochar properties govern soil microbial biomass, whereas soil properties determine soil microbial diversity. A clear effect on the microbial growth, diversity, and community compositions in soil was observed after the addition of biochar, which provides growth promotion due to the change in soil properties (Dai et al, 2021). This was governed by the porosity, labile C, alkaline pH, and CEC of biochar, and it varies with biochar types, production temperature, and feedstock type (Dai et al, 2021).…”

Benefits of Biochar Addition in a Sustainable Agriculture Practice: Soil Nutrients Dynamics, Enzyme Activities and Plant Growth

Biochar is a carbon-rich material resulting from the pyrolysis of plant and animal biomass. Biochar has a long history as a soil amendment for centuries since the Mayan civilization. Attaining sustainability in agriculture is not easy; however, the addition of biochar may reduce the adverse effects of numerous malpractices in conventional agriculture. Biochar benefits soil physicochemical properties such as soil bulk density, aggregate stability, porosity, water holding capacity and soil organic carbon content. However, it is essential to focus on the negative aspects of biochar in terms of atmospheric emissions during the production and occupational health and safety at the time of use. Still, there are many benefits and detriments of the application of biochar, i.e., the priming effect; thus, this review highlights the importance of further research on the application of biochar as a soil amendment. It has been understood that the lack of long-term field studies in various soils using commercially produced biochar may restrict the knowledge of biochar's true potential and effect on soil nutrient dynamics, microbial structure, and crop yield.
