Abstract Biochar is an effective ameliorator for soil quality improvement and nutrient reuse from biomass; however, the effect of biochar application on potassium (K) availability, plant K uptake, underlying mechanisms have not been well‐elucidated. To address this, variation in forms, aggregate stability, aggregate‐associated concentration, as well maize were investigated a field experiment after 9 years amendment. The treatments included no NPK fertilizer (CK); treatment (F); applied...
Soil microbial organisms are conducive to SOC sequestration. However, little attention has been given the contributions of living MBC and necromass carbon pool under biochar straw amendments. The aims study were explore (1) effects maize on MBC, POC, MAOC, DOC carbon; (2) contribution pool; (3) relationships among soil community structure, other fractions application for nine consecutive years. Three treatments studied: CK (applied chemical fertilizer only), BC (biochar applied annually at a...
Urea is a commonly used nitrogen (N) fertilizer that contributes to world food production, and there have been increasing concerns about relatively low urea-N use efficiency. Biochar has shown the potential mitigate N loss, but how biochar influences urea hydrolysis underlying mechanisms are still unclear. In this study, long-term biochar-amended upland, paddy greenhouse soils were sampled at depths of 0–20 20–40 cm in Haicheng City, Northeast China. Soil contents, rates (UHRs), total,...
Biochar and sulfur are considered useful amendments for soil cadmium (Cd) contamination remediation. However, there is still a gap in the understanding of how combined biochar application affects Cd resistance rice, role accumulation iron plaque expression efflux transporter-related genes unclear this type treatment. In study, we screened an effective combination (0.75 % biochar, 60 mg/kg sulfur) that significantly reduced content rice roots (32.9 %) shoots (12.3 %); amino acids their...
The aim of this study was to investigate the changes that occur in molecular form and surface morphology aged biochar explore dynamics aging various types soil. For purpose, rice hull heated 500 °C for 30 min. Approximately 15% fresh incubated either acidic red soil, weak alkaline sandy or coastal solonchak 1 13 months. Aged biochars without soil were also prepared. characteristics analyzed terms elemental composition, specific area, pore size, together with scanning electron microscopy...
A three-year rice pot experiment was conducted to investigate the effects of biochar on cadmium (Cd) accumulation in and Cd fractions soil. The derived from farmland waste applied contaminated paddy soil at various application rates (0, 1, 2, 4%). dry matter accumulations rice, contents organs, fraction distributions were measured. In a 3-year experiment, results indicated that treatments reduced exchangeable concentrations by 28.5 59.4% soil, total 2.7 23.8%, promoted growth 0.7 3.9%. 2% 4%...
Biochar is a potential amendment for the remediation of Cd-contaminated soils. Although immobilization effect biochar on soil Cd has been studied under indoor laboratory conditions, rice uptake and fractions field conditions still poorly understood. Here, content different organs in were characterized three years after application amounts (0, 7.5, 15, 30 t ha−1, 3 ha−1 year−1). The brown rice, husk, leaf, stem sheath, root treatment could be maximally reduced by up to 26.25%, 20.16%, 20.74%,...
Abstract Soil nitrogen (N) transformation is vital in determining farmland N availability. Although many studies have investigated the effect of biochar on retention and loss via leaching gaseous emissions, few determined dynamics gross during crop growth long‐term biochar‐amended soils compared with that its feedstock. In this study, we conducted a five‐time field measurement soil turnover rates 15 isotope pool dilution maize 2021. Three treatments were employed, including no amendment,...
The study was carried to determine the labile carbon contents in biochar pyrolyzed under different temperatures and its effect on urea hydrolysis rate. Corn stovers were at highest temperature of 300°C, 500°C 700 °C produce fresh biochar. Soil incubation experiment conducted with application rate 0% 2% presence urea. results showed that biochars accelerated hydrolysis, high have more significant soil pH enhances acceleration than low temperature. Moreover, produced 300°C contains relative...
This study investigated the effect of corn straw biochar on decomposition, nutrient transformation, and bacterial community characteristics in decomposition process. A 90-day microcosm incubation experiment was performed to assess effects (500 °C, 1 h) process resulting product. Four amendment rates (0%, 5, 10, 15%, as mass fractions biochar) three different addition times (1st day, 30th 60th day) were set total. The results showed that significantly increased pH by 0.71–0.73 electrical...
Biochar as a soil amendment has been shown to improve quality and crop growth. However, biochar's effect on urea-N use efficiency in long term is not well elucidated. Here we studied (15N isotope) allocation plants the presence of maize (Zea mays L.) stover biochar (equivalent 46 t ha-1) during 4-yr pot trial. Results showed that only increased biomass (about 9%) with high amount urea addition, which indicates dry weight by application could be attributed synergistic effects between urea....
Excellent mechanical sensitivity: incorporating trinitrophenyl into azo-1,3,4-oxadiazole compounds results in a heat-resistant explosive with excellent impact and friction sensitivity, along good thermal stability.
ABSTRACT Straw biochar is an effective amendment at improving soil aggregate structure and increasing carbon potassium (K) content. However, little information available on the relationship between organic (SOC) aggregate‐associated K distribution under long‐term application conditions. To address this, a field trial established in 2013 was used to examine impact of (B 0 : B 1 2.625 t ha −1 year ) fertilizer (K 60 kg variation reveal associated influencing factors. A total four treatments ,...
Three kinds of cellulose nanocrystals (CNCs) were added into waterborne polyurethane (WPU) and nanocomposite films that prepared by solution casting. The influence different ionic function groups on microstructure properties composite was investigated. Compared with sulfated CNCs (SCNCs) TEMPO oxidized (TOCNCs), FE-SEM images showed cationized (CaCNCs) had better dispersion in films. thermal decomposition these delayed 15 °C compared pure WPU film. tensile strength fracture work CaCNC/WPU...
