Abstract :

The excessive application of nitrogen (N) fertilizers can have detrimental environmental and economic impacts. Enhancing N use efficiency (NUE) through biochar application may help mitigate these losses while promoting plant growth. However, different biochar types may influence NUE differently. To investigate these effects, a greenhouse pot experiment was conducted to assess the impact of two biochar types on N dynamics. Four treatments were applied: control (CK), fertilizer (F), sawdust biochar + fertilizer (SBF), and rice straw biochar + fertilizer (RBF). A 15N tracer technique was used to evaluate N accumulation and NUE in C. camphora. Results indicated that biochar-fertilizer combinations significantly improved soil inorganic N (NH4+-N and NO3--N) retention, this was attributed to biochar's high surface area and functional groups enhancing N ion sorption. Additionally, biochar-amended treatments (RBF and SBF) increased soil total N, 15N content and plant N uptake. Notably, by the final sampling period, plant total N content in the RBF treatment was 34.62 %, 16.67 %, and 9.38 % higher than in CK, F, and SBF treatments, respectively. Furthermore, 15N content in the RBF treatment was significantly greater than in SBF and F, showing increases of 26.51 % and 30.19 %, respectively. Biochar application also markedly improved NUE, with increases of 103.77 % and 27.86 % in RBF and SBF treatments, respectively, compared to the F. Similarly, soil fertilizer N recovery was 49.92 % and 43.94 % higher in RBF and SBF soils, respectively, than in F. The enhanced urease and protease activity in biochar-amended soils likely contributed to these improvements in fertilizer recovery and NUE. Overrall, our findings demonstrate that first the magnitude of N retention and NUE enhancement varies with biochar type. Second, combining biochar with fertilizer improves fertilizer N retention, NUE, and recovery, ultimately enhancing C. camphora productivity.

Hydrogen Peroxide-Modified Biochar Alters Soil Inorganic Nitrogen Dynamics, Enzyme Activities and Enhances Fertilizer Recovery in Fertilized Soil: A 15N Urea Tracer Study SCIE

Abstract :

The adverse environmental consequences of inorganic nitrogen (N) loss from fertilized soils remain a global issue. The oxidation of biochar may improve its capacity for retaining N in soils; nevertheless, the rate-dependent N retention capacity of oxidized biochar derived from different feedstocks and their impact on the associated microbial enzymatic regulators remains uncertain in fertilized soils. Using the 15N tracer technique, oxidized biochar derived from poultry manure, rice straw, and tobacco stem was comparatively assessed with raw biochar from the same feedstock on inorganic N dynamics and N recovery in fertilized soil. Results revealed that oxidation enhanced the intensity of organic functional groups, cation exchange capacity (CEC), and surface properties for all biochar types, leading to an increase in NH4+ sorption and a decrease in NO3- concentration in oxidized biochar-treated soil. This modification resulted in an overall gain in the retention of N by 3%, 28%, and 27% in the treatments with oxidized biochar applied at 1% (w/w) for oxidized poultry manure biochar (OPBB), oxidized rice straw biochar (ORBB) and oxidized tobacco straw biochar (OTBB). Consequently, an increase in fertilizer N recovery rate of 13%, 46%, and 82% was recorded in OPBB, ORBB, and OTBB treatments compared to their raw biochar. Furthermore, plant-derived oxidized biochar increased N retention more than manure-derived biochar. In addition, the oxidized biochar treatments reduced soil urease activity, which was connected to a decrease in the quantity of NH4+ and increased the resident time of fertilizer N in the soil. This study demonstrates that, unlike raw biochars, oxidized biochars hold great potential for reducing inorganic nitrogen dynamics, which could reduce N loss from fertilized soils alongside increasing N resident time in the soil.

Mechanistic insights into enhanced nitrogen retention and microbial nitrogen cycling in soil-plant systems mediated by hydrogen peroxide-modified biochar SCIE
期刊论文 | 2025 , 464 | GEODERMA
Abstract&Keyword Cite

Abstract :

Minimizing nitrogen (N) loss from fertilized soils remains a critical environmental challenge. While modified biochars can improve N management, concerns about cost, pollution trade-offs, and secondary environmental risks underscore the need for cleaner alternatives. This study evaluated hydrogen peroxide-modified biochars from poultry manure and rice straw for their effects on N retention, plant uptake, and microbial dynamics. A column and pot experiments were conducted, with 15N-labeled urea applied in the pot experiment. Treatments included oxidized rice straw biochar at 1 % (ORBH) and 0.5 % (ORBL), its raw form (RB); oxidized poultry manure biochar at 1 % (OPBH) and 0.5 % (OPBL), its raw form (PB); fertilizer-only (F); and a control. The ORBH and OPBH significantly reduced ammonium leaching by 32 % and 29 % relative to F, and by 20 % and 8 % than their raw forms. Nitrate leaching decreased by 59 % (ORBH) and 61 % (OPBH) versus F, and by 51 % and 22 % compared to RB and PB, respectively. Enhanced N retention was attributed to improved surface properties of oxidized biochar that increased N sorption. Oxidized biochars also decreased urease activity and slowed N transformation, promoting better immobilization-mineralization turnover. Fertilizer recovery was significantly higher in ORBH (75 %) and OPBH (60 %) than in F (43 %). Predicted gene abundances of key N-cycling microbes were higher under ORBH and OPBH, potentially reflecting a slow-release N effect that enhanced plant uptake. These findings demonstrate that oxidized biochars can serve as effective soil amendments to enhance fertilizer N efficiency and reduce N losses.

Evaluation of long-term organic carbon dynamics and organic matter stability in a cultivated paddy soil using a carbon and nitrogen stable isotopes-based model SCIE

Abstract :

Understanding soil organic matter (SOM) stability and carbon storage under long-term intensive land management systems is vital for estimating the C sequestration potentials of agricultural lands. Available methods currently used for measuring the stability of SOM, such as radiocarbon dating, are expensive. However, a costeffective and reliable stable isotope-based model was developed for grasslands which utilizes the C/N ratio and delta 15N of soils to determine the stability of SOM. We applied this model to test for the first time its usefulness for evaluating SOM stability in the top and subsoils of a subtropical paddy field cultivated for 37 years. We also compared paddy soil's SOM stability and carbon storage under different fertilizer treatments. Treatments evaluated were a control (CK), inorganic fertilizer (NPK), NPK+cattle manure (NPKM), and NPK+rice straw (NPKS). Results showed that the C/N ratios and delta 15N signatures of POM and mOM proved effective in predicting SOM stability as predicted by the model. SOM stability increased with depth across the treatments, especially in NPKM and NPKS in the deeper soil layer compared to CK and NPK. Introducing delta 13 C as an indicator further strengthened the model, revealing higher delta 13 C accumulation in the subsoils, indicating higher C sequestration. Further insights showed that unlike in the CK treatment, the use of NPKM and NPKS significantly increased SOC accumulation by increasing the proportion of mineral-protected organic matter (mOM) compared to the microbial-accessible particulate organic matter (POM). The abundance of mOM associated with a lower rate of decomposition in the paddy fields and the incorporation of higher 13 C in the subsoils under NPKM and NPKS were key factors that enhanced the long-term increase in organic C and SOM stability. Thus, the stable isotopebased model proved a reliable proxy for estimating SOM stability in paddy fields.
