Biochar–Microbial Synergistic Systems for Nitrogen and Phosphorus Removal in Polluted Waters: Mechanisms, Studies, and Insights (2025)

Eutrophication caused by increasing non-point source pollution has resulted in the accumulation of nitrogen and phosphorus in water bodies, leading to severe algal blooms, oxygen depletion, and ecosystem degradation. However, conventional remediation technologies often face limitations in efficiency and sustainability. Biochar, derived from organic waste, has gained attention for its strong adsorption capacity. Recent advances show that combining biochar with functional microorganisms—forming bi

Synergistic Effects of Biochar and Phosphorus Fertilization on Wheat Growth, Pollution Reduction, and Soil Enzymatic Behavior (2023)

This research, conducted in the wheat fields of West Mashhad, Iran, explores the synergistic effects of nano-technology and biochar on wheat cultivation and greenhouse gas emission. There is a growing global interest in recent years to decrease air pollution through augmentation of greenhouse gas emission. Moreover, this study investigated using a factorial experiment and various levels of phosphorus and biochar treatments, the study aimed to understand the dynamics of their combined influence o

Effects of biochar on nitrogen and phosphorus retention in the coastal wetland soil of the Yellow River Delta, China (2021)

Nutrient deficiency (nitrogen, phosphorus) strongly limited the productivity of the degraded coastal soils in the Yellow River Delta. Biochar (BC) is a kind of porous carbonaceous material. It has raised wide interests because of their multiple benefits in soil improvement. The effects of biochar on the retention of nitrogen and phosphorus varied with the types of biochar and soil properties. In this study, a maize straw derived BC was applied into a coastal salt-affected soil collected from the

Impact of Various Levels of Nitrogen, Potassium, Phosphorus and Biochar on Soil Physico-chemical Properties and Yield of Black gram (Vigna mungo L.) Var: Shekhar-2 (2024)

At the “Central Research Farm, Soil Science and Agricultural Chemistry Department, SHUATS, Prayagraj”, an experiment titled "Impact of various levels of Nitrogen, Potassium, Phosphorus and Biochar on Soil Physico-chemical Properties and Yield of Black gram(Vigna mungo L.)Var: Shekhar-2" was carried out during the Zaid season of 2023–2024. A randomized block design was used, consisting of three variables and three levels of NPK (at 0, 50, and 100% ha-1) and biochar (at 0, 50, and 100% ha-1). An e

Corn Stover Biochar Amendment Enhances Nitrogen and Phosphorus Transformations, Microbial Community Diversity, and Enzyme Activities in Agricultural Soil (2025)

Corn stover biochar amendment significantly influences nitrogen (N) and phosphorus (P) transformations, microbial community composition, and enzyme activities in continuous cropping soils. This study aimed to identify the optimal biochar application rate for enhancing N and P nutrient availability in Solanum lycopersicum L. continuous cropping systems, providing theoretical and technical foundations for mitigating continuous cropping obstacles. A soil experiment under rain-out shelters employed

Unravelling the role of biochar-microbe-soil tripartite interaction in regulating soil carbon and nitrogen budget: a panacea to soil sustainability (2025)

Abstract Global food requirements necessitating enhanced crop productivity have negative consequences such as soil degradation due to acidification and nutrient leaching escalated by excessive application of chemical fertilizers and consequently increasing greenhouse gas emission. This has sought sustainable organic approaches like soil amendment with biochar to mitigate the adverse consequences of these effects, ensuring balanced ecosystem functioning. Reconciling various studies, thi

Plant-soil nitrogen, carbon and phosphorus content after the addition of biochar, bacterial inoculums and N fertilizer (2020)

Abstract The use of biochar in combination with mineral or biological amendments in order to improve its influence on soil-plant properties has received growing attention. The changes of N, C and P content in Lactuca sativa var. capitata aboveground plant biomass and soil after the addition of beech wood biochar combined with the addition of bacterial inoculums (Bacofil and Novarefm) and N fertilizer have been studied using s

Dissolution of viscose rayon multifilament yarn in the ionic liquid 1-ethyl-3-methylimidazolium acetate studied using time–temperature superposition (2023)

Abstract Wide-angle X-ray diffraction (WAXS) and mechanical testing techniques are used to track the dissolution of a viscose rayon multifilament yarn in the ionic liquid 1-ethyl-3-methyl-imidazolium acetate [C 2 mim] + [OAc] − for different times and temperatures. In the dissolution process, the oriented cellulose II crystals in the regen
