Abstract Biochar and organic fertilizer are widely supported to maintain crop production sustainable development of agroecosystems. However, it is unclear how biochar alone or in combination regulate soil functional microbiomes their relationships ecosystem multifunctionality (EMF). Herein, a long-term (started 2013) field experiment, containing five fertilization treatments, was employed explore the effects applications on EMF (based 18 indicators productivity, nutrient supply, element cycling, microbial biomass) bulk rhizosphere [normalizing abundances 64 genes related carbon (C), nitrogen (N), phosphorus (P), sulphur (S) cycles]. Compared with single-chemical fertilization, inputs significantly enhanced most ecosystem-single functions and, particular, increased by 18.7–30.1%; taxa C-N-P-S cycles varying degree. The combined application showed better improvement these compared using them individually. Most populations soil, especially involved C degradation, nitrification, nitrate-reduction, P mineralization, S cycling positive associations at different threshold levels, which ultimately regulated pH availability. These results highlight strong links between agroecosystem functions, as well providing scientific support for inclusion agricultural services amendments. Graphical

Excessive use of chemical fertilizers negatively impacts crop productivity and farmland ecosystem, impeding sustainable agricultural progress. Consequently, there is an immediate need for a fertilizer reduction strategy that ensures improves soil quality the ecological environment farmland. This study implemented three-year (2018–2020) field experiment with two methods (direct organic substitution) to investigate their effects on wheat productivity, quality, heavy metal pollution risk microbial characteristics. The results showed substitution treatments (OF1, OF2 OF3) improved most plant (nutrient uptake yield its components) properties (soil nutrients carbon nitrogen fractions), leading increased index (CPI, by 9.18 %-16.39 % 14.14 %-23.36 %) (SQI, 84.67 %-138.86 104.11 %-175.91 compared conventional fertilization (CF) direct (RF1, RF2 RF3) in 2019 2020. Additionally, enhanced diversity network complexity bacterial community, while raising (SPI, 9.30 %-12.84 12.20 %-18.49 without causing pollution. Thus, it recommended adopt as primary production. approach will ensure yield, improve characteristics, but long-term application requires monitoring changes metals. Overall, this provides guidelines implementing scientific practices, thus contributing health sustainability ecosystems.

The Chinese Chernozems face extreme challenges of soil degradation and crop productivity decline. Biochar-based organic fertilizer (BOF) is effectively applied to improve yield quality. Nonetheless, the mechanisms involved in enhancement interaction with root traits, quality, microorganisms after BOF application remain unclear. Herein, a two-year field experiment three rates [3.0 Mg ha−1 (BOF3), 6.0 (BOF6), 9.0 (BOF9)] was conducted evaluate impact on microorganisms, no as control treatment (CK). Compared CK, increased maize by 9.1 ∼ 32.0 % second year application, highest (16.1 ha−1) obtained BOF6. plant growth index 29.7 98.9 %, mainly attributed increase volume (2.4 57.4 %), aboveground biomass (31.4 44.0 nitrogen (N) uptake (123.2 216.0 %). quality not only topsoil (27.7 31.1 %) but also subsoil (22.7 25.1 BOF, particularly two (BOF6 BOF9). This ascribed notable microbial carbon, total N, NH4+-N, N-acquiring enzyme activity (normalized leucine aminopeptidase alkaline phosphatase). Moreover, abundance Actinobacteria, Mortierellomycota at 0–40 cm, Chloroflexi 0–20 Acidobacteriota, Ascomycota 20–40 which confirmed their key roles activating nutrient subsequent enhancing stimulating growth. Overall, biochar-based rate promising regime enhance regulating keystone taxa, thereby boosting Chernozem soil.

Cereal plants form complex networks with their associated microbiome in the soil environment. A system including variations of numerous parameters properties and host traits shapes dynamics cereal microbiota under drought. These multifaceted interactions can greatly affect carbon nutrient cycling offer potential to increase plant growth fitness drought conditions. Despite growing recognition importance agroecosystem functioning, harnessing root remains a significant challenge due interacting synergistic effects between traits, properties, agricultural practices, drought-related features. better mechanistic understanding root-soil-microbiota associations could lead development novel strategies improve production In this review, we discuss for improving environment suggest roadmap benefits these drought-resilient cereals. methods include conservative trait-based approaches selection breeding genetic resources manipulation environments.

Environmental pollution is caused by the unsustainable use of nitrogen (N) fertilizers and pesticides. Biochar (BC) a carbon-based material applied to remove excess nutrients pesticides from environment. In pot experimental research, N fertilizer alone different biochar types were in soil evaluate cauliflower growth, quality, leaching agricultural contaminants. BC addition had increased nutrient availability based on feedstock origin. The surface structure results SEM showed that pore size was equal 8.94 7.24 µm for mixed wood biochar, respectively. Nitrate concentrations percolation water 43.78 76.82 mg/L treated with pesticides, NO3− 106.76 mg/L. Biochar’s binding depends its nature structure.

The use of organic fertilizers instead chemical can improve soil pH, help to maintain health and enable landowners achieve or ecological-status agriculture. Rapeseed cake, sheep manure, biofungal fertilizer are considered be effective amendments quality. However, there have been few studies on the effects three strawberry production, physicochemical properties, inter-root microbial community structure. In this study, field experiments were conducted investigate differences in growth, quality, yield, structure diversity bacterial fungal communities under four treatments: no (CK), rapeseed cake (T1), manure (T2) bio-organic (algae-optimized bacteria) (T3), relationship between properties analyzed. Our results shown that these promoted growth some extent. available phosphorus, ammonium nitrogen, sucrase, protease urease T2 treatment significantly increased by 50.62%, 54.14%, 276.50%, 129.47%, 232.61%, 232.00%, respectively, compared with control. fungi most abundant diversified treatment. Soil key enzyme activities varied different treatments, nutrient content carbon nitrogen metabolizing being highest A Pearson correlation analysis showed matter was closely related communities. redundancy (RDA) main variables included nitrate (NN) rapidly potassium (RAP), while alkaline dissolved (ADN) (AN). Overall, release transformation nutrients affecting soils, which beneficial supply improvement application had best effect.
