Abstract Saline acid sulphate soils are commonly ameliorated using traditional amendments like lime and cow manure. Biochar, derived from crop residues, is another potential remedy for this type of soil. Their combined use may create synergistic effects, necessitating further investigation. This study aims to assess the impacts biochar with on soil quality, properties rice yield. A field experiment was established six treatments: no‐amendment (control), lime, manure, biochar, manure ( Oryza sativa ) planted in four replicates. The revealed that effects these were driven by their inherent characteristics secondary processes, such as neutralization. Combining significantly increased pH (6.2), exchangeable calcium (648.6 cmol(+) kg −1 ), while reducing aluminium (11.83 iron (37.5 compared control. Meanwhile, combining notably enhanced Mehlich‐1 phosphorous (3.4 mg organic carbon (4.99%), ammonium (27.0 cation exchange capacity (17.2 ). Biochar exhibited greater synergetic quality than when lime. Consequently, combinations improved index, which a strong correlation yield biomass its value below 0.4. finding indicates exhibit insignificant growth. Further research needed elucidate findings explore optimal application rates concerning management practices.

Abstract Arsenic (As) detoxification in polluted soils by iron-based materials can be mediated the endogenous soil organic matter (SOM), nevertheless mechanisms remain unclear. Herein, SOM a paddy was substantially removed to understand its roles on As immobilization biochar-supported zero-valent iron (ZVI/BC). The results demonstrated that ZVI/BC application significantly decreased bioavailability 64.2% compared with control under anaerobic condition. XPS and HR-TEM suggested mainly invoked formation of ternary complexes (i.e., As-Fe-SOM). However, depletion compromised efficacy for 289.8%. This is likely because increased fulvic acid OH − contents soils. Besides, proportion As(III) available fraction, but altered associated As(V) reduction. That is, reduction resulted from reductive capacity ZVI pristine soil, As(V)-reducing bacteria contributed greater SOM-depleted soil. Additionally, boosted abundances Fe(III)- such as Bacillus Ammoniphilus soils, which enhanced dissimilatory arsenate Thus, this work highlighted importance remediation As-contaminated ZVI/BC.

Nowadays, the scarcity of energy resources is promoting search for alternative sources, boosting interest in use forest lignocellulosic residue sector. In this study, focus on recovery from two residues originated during pruning ornamental trees (Horse Chestnut, CI, and False Acacia, FA). Both conventional flash pyrolysis techniques were applied. The experimental variables obtained study thermal behaviour thermogravimetric analysis. It was carried out under 5 heating rates kinetic parameters estimated using Flynn-Wall-Ozawa method. Results denoted higher maximum mass loss rate values same release temperature regions FA experiments. Also, samples had lower final processes. However, activation so close both species. also linked to faster reactions according frequency factor outcomes. Conventional a horizontal oven original design at 25 °C/min, 750 °C 60 min permanence that temperature; tested 850 °C. these processes, three fractions obtained: bio-char, bio-oil gas. physicochemical attributes bio-chars suggested their potential utility as biofuels (28.4–29.8 MJ/kg), adsorbent precursors or soil additives. bio-oils dominant monoaromatic hydrocarbons nature, with phenols being most abundant (≥60%), while contain mainly polycyclic aromatic hydrocarbons. gases contained up vol% CO2; high combustible gas content (CO, CH4, H2) low CO2 (<25 vol%). As result, calorific value (18.06 MJ/kg) exhibited threefold increase compared produced through (6.04 MJ/kg).

The effect of biochar addition on enzyme stoichiometry and regulatory mechanisms in saline-alkali soil is still vague. We studied how five years (2018–2023) applying 10 t ha−1 yr−1 influences soil’s chemical microbial properties, element utilization efficiency, resource limitations the Tarim River basin. Low, medium, high nitrogen fertilization (kg N ha−1) irrigation (W) (mm) with or without (B) were as follows: low (LNLW, 100/140), mid (MNMW, 200/220), (HNHW, 300/320), LNLWB, MNMWB, HNHWB. Biochar application (LNLWB, HNHWB) increased organic carbon (+61%, +55%, +59%), total (+9%, +16%, +8%), phosphorus (+6%, +5%, +27%), (+75%, +86%, +28%) P use efficiency (+60%, +45%, but decreased biomass (−6%, −29%, −45%), −7%, −7%). alleviated C limitation MNMW HNHW. In conclusion, a 1/3 reduction compared HNHW (MNMW), can greatly alleviate improve fertility saline-alkaline soils.
