The decline in soil quality is becoming a significant process of degradation. Optimizing organic fertilizer incorporation practices cropland essential to enhancing crop productivity and health. However, that requires comprehensive understanding yield reaction across an application gradient fertilizer. We investigated the effect on yield, quality, fauna feeding activity from fluvo-aquic soils wheat ( Triticum aestivum )-maize Zea mays ) rotation field. six treatments included were unfertilized N control (UC), traditional chemical (TF, 600 kg ha −1 year ), recommended fertilization (RF, 400 with no rate, low-level 15.0 (RFLO), medium-level 30.0 (RFMO), high-level 45.0 t (RFHO) application, respectively. research findings show increased 26.4%–44.6% for 12.5%–40.8% maize compared RF plots. long-term rate carbon 54.7% 110.6% versus UC plots 27.9%–74.0% (TF RF) treatments, total nitrogen content 41.8% 59.2%, 24.6%–39.2%. inorganic combined significantly enhanced sucrose (30.1%–51.9%), urease (28.4%–38.3%), β-1,4-glucosidase (34.6%–122.4%) activity. Still, nitrite reductase, polyphenol oxidase, catalase lower 27.3%–49.9%, 8.5%–26.3% 23.3%–34.3% than single applications groups. Meanwhile, results showed improved by 35.2%–42.5%, excessive reduced level fauna.

Soil microorganisms play a key role in regulating soil organic carbon (SOC) accrual. Organic amendments with distinct stoichiometry may lead to imbalanced supply of (C), nitrogen (N), and phosphorus (P) the microbiome, causing changes microbial community composition their life strategies, as well enzyme production. However, response these imbalances whether adaptive strategies are related fate SOC pools remain largely unknown low-fertility paddy soil. To address this uncertainty, soils were sampled from 12-year experimental fertilisation trial under integrated application mineral fertilizers three types materials (green manure, rice straw, cattle manure). Stoichiometric between microbes available resources, activities, composition, linkages particulate (POC) mineral-associated (MAOC) C investigated. The results showed that despite equal input, strongest increase MAOC occurred smallest C:N imbalance C:P imbalance, suggesting alleviation N P limitation was inductive accrual stable fraction. Additional lower C: nutrient ratios shifted towards prevalence r-strategists, manure addition supporting copiotrophic bacteria green favouring fungi. Importantly, relative abundances Proteobacteria, Gemmatimonadetes, Actinobacteria belonging copiotrophs negatively but positively POC MAOC, while Chloroflexi, Basidiomycota Glomeromycota oligotrophs exhibited reversed relationships. In addition, greater associated an biomass decrease biomass-specific P-acquiring activity. Random forest analysis partial least squares path model revealed played important indirect shaping by concurrently biomass, production, whereas pool predominantly directly controlled proportion macroaggregates. These provide empirical evidence for stoichiometric control communities feedback pools, highlighting low C:nutrient ratio long-term storage persistence intensively managed soils.

Abstract Continuous cropping has a negative effect on soybean yield. In this study, positioning experiment was conducted starting in 2015, with three treatments: maize–soybean rotation (SMR), 2-year maize, (SC2), and 8-year continuous (SC8). We determined yields (2015–2022) analyzed soil microbial communities, functions, metabolites composition the 0–20 cm tillage layer using metagenomics technology GC–MS during flowering 2022.

Application of Manure Rather Than Plant-Origin Organic Fertilizers Alters the Fungal Community in Continuous Cropping Tobacco Soil

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: April 19, 2022

Continuous cropping leads to the development of serious fungal diseases in tobacco plants and depleted yield ( Nicotiana tabacum ), which can be mitigated by organic fertilization. Yet, we know little about how fertilizers affect community continuous soil. In this study, investigated soil after 11 years planting with chemical fertilization (CF) or combined obtained from plant animal origin, including oil cake (CFO), straw (CFS), farmyard fertilizer (CFM). The predominant phyla Ascomycota (70%) Mortierellomycota (15%) were identified all treatments. A significantly higher proportion Pyrenochaetopsis lower relative abundance Sordariomycetes observed CFM group compared controls. Compared CF non-fertilized control (CK), CFO CFS led species richness P < 0.05), while a less uniform community, indicated Shannon Simpson diversity indices 0.05). Pearson’s correlation redundancy analysis suggested that fertilizations primarily influenced altering nutrient conditions, among carbon total phosphorus correlated composition Notably, FUNGuild annotation other treatments showed no significant effect on trophic modes, strongly increased saprotrophic fungi more than 30% thus preventing prevalence potential pathotypes symbionts. results suggest type is essential long-term effects application animal-origin manure seems better choice plant-origin materials fields.

Abstract Biochar has been considered an effective approach as soil amendment for decreasing incidences of disease and regulating microbial populations in continuous-cropping soil. Although researches have extensively focused on changes microbes unbalance nutrition soil, the relationship between properties pathogens by biochar application remains poorly understood. In this study, we applied ITS ribosomal RNA gene profiling to analyze tobacco root microbiota non-biochar treatment a 3-year field, comparing firstly planting control. We found that decreased relative abundance fungal ( Ceratobasidium Monosporascus ), which are prime rot Using RDA, co-occurrence PLS-PM approaches, provided evidence there was negative correlation genera (especially ) polyphenol oxidase (PPO) activity (R 2 incidence rate = − 0.930, R index 0.905, both p < 0.001). The PPO up-regulated different intensities. Together, demonstrated regulated suppress pathogens, further decrease rot. Notably, forward continuous cropping more improvement than other treatments. data should help appropriate timing alleviating obstacle. Graphical abstract
