Acidic additives have garnered significant attention due to their ability reduce ammonia (NH3) emissions, enhance nitrogen retention, and balance function with cost-effectiveness. This study aimed investigate the potential of oxalic acid (OA) in reducing gas promoting compost humification, enhancing nutrient retention during co-composting chicken manure. Moreover, comparative analysis effects economic benefits was conducted among OA groups varying concentrations (OA1: 0.03 mol·kg−1, OA2: 0.10 OA3: 0.15 mol·kg−1) a sulfuric (SA) group (SA1: mol·kg−1). The results indicated that addition can extend thermophilic phase some extent achieve required composting maturity. As amount increased, NH3 emissions (p < 0.05) total loss rate decreased; however, this also increased cost. No difference observed between SA1 OA1 0.05). It is worth noting SA SO42− content, leading an increase 113.52% H2S emissions. In contrast, resulted reduction by 29.92–45.90%. terms analysis, most effective (OA1 > OA2 OA3 SA1). Thereby, proved be good alternative for manure, mol·kg−1 recommended.

Abstract. Soil humic substances (HSs) typically alter their electrochemical behaviours in the pH range of 1–12, which simultaneously regulates stability organo-minerals by modifying HS functionalities. This process facilitates both biotic and abiotic transformations, consequently leads to export degradative byproducts (e.g. components, nutrients) from soils into surrounding aquatic environments through water and/or rainwater discharges. However, solubility features, environmental consequences, mechanisms HSs, including acids (HAs), fulvic (FAs), protein-like (PLSs), under different pHs remain unclear. To respond these issues, we used two soil extracts were fractionated 12–1. The pH-dependent presence or absence fluorescence peaks individual components reflected functional group proton/electron exchange features at low high values, related insolubility. In particular, alkaline (≥pH 9) yielded anionic forms (-O- -COO-) phenolic OH carboxyl groups HACS, resulting decreased electron/proton transfer functionalities, as indicated decline peak maxima, whereas protonic functionalities –COOH, –OH) HSs lower resulted formation highly available remaining uncomplexed forms. HA fractions increases with increasing pH, insolubility decreasing determines initial precipitation 6 final 1, amounting approximately 39.1 %–49.2 % 3.1 %–24.1 total dissolved organic matter (DOM), respectively, soils. Elemental analysis results demonstrated that C N contents HALS-pH those O, S, H higher than HACS-pH 6, suggesting preservation without S acquisition possibly because being complexed minerals, which, turn, would determine fraction. FACS + PLSCS showed relatively O% respect FALS PLSLS, implying mineral protection. Fourier transform infrared (FTIR) show significantly reduced absorptions 3300–3600 800–1200 cm−1) existence strong intermolecular interactions among groups, due insoluble originally minerals. PLSLS exhibited stronger bands 3414–3429 1008–1018 cm−1 PLSCS, a interaction derived various organo-mineral complexes PLSCS. These indicate arises via organo-metal along HApH rainwater/water discharge, 2 FA PLS appears be soluble acidic thereby transported ambient waters discharge groundwater infiltration. Therefore, behaviour greatly contributes better understanding progressive transformation, mobility/transportation, immobility/accumulation conditions, relevant implications for sustainable management practices DOM dynamics.

Soil phosphorus is heavily restricted by soil acidification and salinization. There a need to determine biological solution for this issue replace the overuse of chemical fertilizer that aggravates adverse conditions, such as salinity, acidity, metallic toxicity. Therefore, study aimed at determining dynamics in terms soil, growth, yield rice under supplementation phosphate (P)-solubilizing purple nonsulfur bacteria (PNSB), Cereibacter sphaeroides ST16 ST26, salinized collected from An Bien district, Kien Giang province, Vietnam, greenhouse conditions. The experiment followed completely randomized block design with two factors four replications. In particular, reduced percentages P (A) were 0%, 25%, 50%, 75%, 100% P. supplementations C. strains (B) negative control, ST16, mixture both ST26. results showed supplying ST26 insoluble content 10.1–10.6% Fe-P, 10.3–12.2% Ca-P, 12.7–43.1% Al-P increased available 8.33–27.8%, leading total uptake plants increasing 29.4–56.1%. also Na+. growth components rice, greater 26.5–51.0%. Supplying each strain 50–100% recommended. Ultimately, inoculation bacterial allowed reduction percentage recommended but remained still.
