Soil acidification poses a significant threat to the healthy development of agriculture. Traditional soil amendment involving lime (L) has notable limitations. Therefore, developing alternative methods address holds significance. In this study, calcium lignosulfonate (LC) was introduced different acidic purple soils assess its efficacy in reducing acidity and enhancing fertility. The density functional theory (DFT) calculation employed analyze potential interaction mechanisms LC decreasing acidity. results indicated that 2 ‰ addition improved pH by 2.8 organic carbon 26 % poor-quality extremely (with an initial 4.4) after 40-day pot experiment. findings from Fourier Transform infrared spectroscopy (FTIR) DFT suggested competitive adsorption between Al3+ Ca2+ on surface groups (e.g., –SO3- –OH) contributes immobilization exchangeable Al3+. These validate feasibility as application for amending underscore advantages fertility enhancement. molecular model extend understanding key mitigating acidification.

Introduction Anaerobic digestion of manure, together with other biowastes, produces biogas that can substitute fossil energy and thereby reduce CO 2 emissions post- greenhouse gas emissions. The final digestate the process is an organic fertilizer rich in plant nutrients recalcitrant constituents. characteristics quality depend on several parameters, such as input feedstocks operational conditions plants. In Denmark, rapid expansion sector recent years has resulted a great variety used first generation plants mainly treated industrial wastes, crops short retention times, while new are co-digesting manure higher amounts lignocellulosic operating longer times. This study evaluated whether this shift feedstock composition could impact post-digestion gases ammonia during storage application digestate. Methods Digestate samples from 2015 to 2023 were collected analyzed for residual methane yields. efficiencies solid–liquid separation applied investigated contents liquid solid fractions evaluated. Results discussion most evident change caused by transition was average increase 52% total solids content digestate, which negatively application. contrast, similar yields fresh matter basis approximately 5 L/kg indicated comparable risks storage. fraction industrially separated presented, average, nutrient concentrations those unseparated presented K, lower ammoniacal nitrogen, N P than basis. yield 101 volatile solids, calorific value 21 MJ/kg indicating its potential additional generation.

Abstract The use of livestock waste as an organic fertiliser releases significant greenhouse gas emissions, exacerbating climate change. Innovative management practices, such treating slurry with plasma induction, have the potential to reduce losses carbon and nitrogen environment. existing research on effectiveness plasma-treated at reducing nitrous oxide (N 2 O) methane (CH 4 ) however, is not comprehensive, although must be understood if this technology utilised a large scale. A randomised block experiment was conducted measure soil fluxes N O CH from winter wheat every two hours over 83-day period using automated chambers. Three treatments receiving similar amount plant-available were used: (1) inorganic (IF); (2) pig combined (PS); (3) (TPS). Cumulative TPS (1.14 g m −2 greater than those PS (0.32 IF (0.13 ). diurnal pattern in observed towards end for all treatments, driven by increases water-filled pore space photosynthetically active radiation decreases air temperature.

Abstract Manure management is a significant source of ammonia emissions in the EU. Ammonia can damage sensitive habitats, pose risk to human health and reduce crop available nitrogen supply from organic materials manufactured fertilizers. Total ammoniacal‐nitrogen liquid consists both un‐ionized gas ammonium solution which are at an equilibrium that pH temperature dependant. At <6 proportion very low, acidification recognized as technique for reducing materials. Air plasma treatment, fixes air using strong electric current, lowers around 5.5, 7–8 untreated A series seven replicated field experiments were used compare effects treated on emissions, yield use efficiency following application winter wheat. Results showed 28%–83% lower than similar mineral nitrate same experiments. The increased fertilizer value (compared with materials) by 45%. reduced requirement purchased applications meet optimum demand.

The application of biogas slurry in agriculture production is regarded as a sustainable method for mitigating the environmental impacts fertilization. To investigate effects on soil nitrogen loss and crop yield, field plot experiment was conducted within wheat–maize rotation system. This study assessed three levels substitution, 50% (BSF), 100% (BS), 150% (EBS), yield silage maize wheat, use efficiency, loss. findings revealed that first year (characterized by high rainfall), led to increased NH3 emissions leaching, resulting notable rise annual Additionally, it observed amount applied increased, also rose correspondingly. However, second (a period drought conditions), despite elevated from slurry, there significant reduction which resulted reductions 14.2% 20.0% BSF BS treatments, respectively, with comparable input fertilizer treatment. Throughout both years, did not decrease notably, treatment even enhanced utilization efficiency. Compared other EBS increase an rate; reduced efficiency N In conclusion, employing replace chemical (equivalent substitution) during years can enhance reduce loss, sustain yield.
