Опубликована: Янв. 13, 2025

The appropriate application of nitrogen fertilizers and biochar to the soil is beneficial for soybean growth, a combination can improve low-nitrogen fertilizer utilization efficiency. However, effect on roots still unclear. Therefore, in this study, we investigate changes endophytic bacterial communities metabolites under different combinations treatments by setting fertilization levels using high-throughput sequencing non-targeted metabolomics techniques. results showed that applying 20 t/ha 180 kg/ha (C2N1) resulted highest yield. By studying community roots, it was observed dominant phyla were Proteobacteria, Bacteroidota, Actinobacteriota, genera Bradyrhizobium, Streptomyces, Rhizobacter. Moreover, metabolic pathway analysis revealed glycosylphosphatidylinositol (GPI)-anchor biosynthesis most significant C0N1 vs. C0N0 comparison group, glycerophospholipid metabolism C2N1 C1N1 group; they both associated with regulatory mechanisms such as plant growth promotion nutrient cycling. Structural equation modeling indicates bacteria have positive impact Bradyrhizobium Rhizobium are observable variables effects bacteria, while Phe-Thr 7-allyloxycoumarin metabolites. Endophytic not only direct crop yield, but also indirectly affect yield through their This study has important scientific value guiding significance improving yields.

Biochar in Sustainable Agriculture: Fertilizer from Natural Resources?

IntechOpen eBooks, Год журнала: 2025, Номер unknown

Опубликована: Янв. 20, 2025

Continuous and excessive use of synthetic fertilizers in food production generates strong pressure on agroecosystems. Therefore, it is necessary to study standardize alternatives that promote environmental health, such as biochar. Biochar (a blackish solid obtained from the pyrolysis vegetable waste, industry animal or water processing waste) characterized by its high content mineral carbon, presence functional groups, richness nutrients potassium (K+). Its soils improves organic matter cation exchange capacity (CEC), which promotes crop nutrition. In addition describing biochar manufacturing processes, this chapter aims emphasize role a fertilizer, stimulating effects soil microbiome enzymatic activity, positive plant health. Understanding biofertilizer can be considered an ecological strategy for production. However, agricultural sector must consider limitations fertilizer.

Exogenous carbon inputs alleviated salt-induced oxidative stress to cotton in salinized field by improving soil aggregate structure and microbial community

Frontiers in Plant Science, Год журнала: 2025, Номер 16

High concentrations of salt ions in salinized soils not only destroy soil structure, but also inhibit crop growth. Straw and straw-derived biochar have great potential improving reducing salinity, environment, alleviating stress. However, the effects mechanisms exogenous addition different carbon sources on aggregate structure microbial community with salinization degrees cotton fields as well antioxidant defense system are still unclear. In this column experiment since 15 March, 2023, three contents (1.5 (S1), 5 (S2), 10 (S3) g/kg) five treatments (straw incorporation: 6 t/hm 2 (C1), 12 (C2); 2.25 (B1), 4.5 (B2); CK: no straw incorporation) were designed. Then, incorporation particle size distribution aggregates, bacterial fungal communities, leaf S1, S2, S3 explored. The results showed that incorporation, especially B2, significantly reduced content soils, increased proportion macroaggregates by 7.01%–13.12%, 5.03%–10.24%, 4.16%–8.31%, respectively, compared those CK. C2, abundances Actinobacteria, Acidobacteria, Enterobacteriaceae, decreased Proteobacteria, Besides, superoxide dismutase (SOD) catalase (CAT) activities salt-stressed leaves, malondialdehyde (MDA) peroxidase (POD) activity, It should be noted effect stress gradually growth increase salinity. summary, could reduce diversity, alleviate cotton. This study will provide a scientific basis for improvement utilization soils.

Biochar is a soil amendment that has the potential to effectively improve salinization. However, there paucity of studies on sodium adsorption using biochar, and mechanism remains unclear. To better understand Na+ surface both pyrochar hydrochar were produced at different temperatures. The capacity influencing factors in biochar analyzed via batch experiments. Pore filling dominated concentration NaCl solution when it was ≤100 mg/L, where wheat straw (WB, 3.95–4.94 mg/g Na) poplar wood chip (PB, 0.62–0.70 presented release Na+, respectively. When >100 WB (25.44–36.45 mg/g) significantly higher than PB (4.46–6.23 mg/g). Both insufficient. In high solution, ion exchange became key determining pyrochar, which K+ contributed more 94% adsorption. findings proposed strategies for structural design used Na These will promote utilization solid biowaste salinization agriculture arid lands.

Soda saline–alkaline stress significantly impedes the rice grain filling process and ultimately impacts yield. Biochar has been shown to mitigate negative of on plants. However, exact mechanism by which biochar influences grain-filling rate in soda soil is still not fully understood. A two-year field experiment was conducted with two nitrogen fertilizer levels (0 225 kg ha−1) five application rates [0% (B0), 0.5% (B1), 1.5% (B2), 3.0% (B3), 4.5% (B4) biochar, w/w]. The results demonstrated that had a significant impact reducing Na+ concentration Na+/K+ ratio grown lands, while also improving its physiological conditions. B1, B2, B3, B4 showed notable increase average 5.76%, 6.59%, 9.80%, 10.79%, respectively, compared B0; time reach maximum weight saw increases ranging from 6.02% 12.47% 7.85% 14.68%, respectively. Meanwhile, particularly when used conjunction fertilizer, notably enhanced activities sucrose synthase (SuSase), ADPG pyrophosphorylase (AGPase), starch (StSase), branching enzyme (SBE) grains lands. Furthermore, yield increased 11.95–42.74% treatments B0 treatment. These findings improves regulating ionic balance, indicators, synthesis key activities, paddy fields.
