Root hypoxia stress and soil nutrient turnover have been related to reduced crop productivity. Aerated drip irrigation (ADI) can effectively enhance productivity yield. However, the response of bacterial community different water dissolved oxygen (DO) concentrations remains elusive due extreme sensitivity microorganisms environmental variations. We investigated effects aerated with DO on properties agronomic performance cucumber, as well contribution community. performed experiments cucumber cultivation in Shouguang, China, including methods (ADI: O2–10 O3–20 mg L−1, non-aerated groundwater: O1–5 L−1) nitrogen (N) application rates: 240 360 kg N ha−1. ADI (particularly O2) significantly improved properties, root growth, yields, use efficiency (IWUE), appropriate fertilizer increased yields. Furthermore, these changes were associated diversity, aerobic bacteria abundance, consolidated population stability within network module. Environmental factors such respiration rate (Rs), DO, NO3−-N significant communities. The FAPROTAX results demonstrated enhanced nitrification (Nitrospira) nitrite oxidation by under ADI, promoting accumulation effective fertility Appropriate concentration is conducive involvement communities regulating growth performance, which are vital for sustainable development facility agriculture.

Background: Vegetation restoration influences soil properties considerably, which in turn interact with microbial community structure and regulate ecosystem stability. However, the influence of physical on has been poorly characterized. Methods: We investigated changes physicochemical bacterial fungal diversity composition after natural (grasslands (GL)) afforestation (artificial forests (AF)) for more than 40 years a karst faulted basin China. Results: Compared that undamaged (NF), AF enhanced organic carbon nutrient contents markedly, whereas GL improved water stable aggregate, bulk density, pH. Alpha analyses suggested vegetation had no significant effect Chao 1 index Shannon communities. according to nonmetric multidimensional scaling analysis results, dissimilarities between NF were distinct those NF. Such diverse responses largely explained by Additionally, pH, porosity, field capacity significantly correlated ( P < 0.05). Conclusion: ecologically fragile areas should focus understanding interactions chemical as well properties.

The current study was undertaken to investigate the dynamic characteristics of tomato crop, such as its plant height and leaf area index (LAI), based on effective cumulative temperature. This assessed under aerated drip irrigation (ADI) conditions application a specific nitrogen (N) dose, their relationship with yield crop formulated. conducted in greenhouse located Zhengzhou, Henan province, China. assessment were two methods, ADI conventional (CK), three N rates, i.e., 0, 140, 210 kg ha−1. logistic Richards models used fit equations for LAI different treatments quantify characteristic parameters understand yield. results revealed that growth fitted well model at R2 > 0.98 (p < 0.01), regardless treatments. found significantly increase maximum rate average over rapid period LAI.

Due to the enclosed environment of greenhouse grape production, supply CO 2 required for photosynthesis is often insufficient, leading photosynthetic downregulation and reduced yield. Currently, optimal concentration production in greenhouses unknown, precise control actual levels remains a challenge. This study aims investigate effects different concentrations on characteristics yield grapes, validate feasibility gas irrigation system, identify production. In this study, system combining enrichment techniques was used with 5-year-old Eurasian variety ( Vitis vinifera L.) ‘Flame Seedless.’ Four treatments were applied: 500 ppm (500 ± 30 µmol·mol −1 ), 700 (700 850 (850 1,000 (1,000 ). As increased, chlorophyll a, b, carotenoids leaves all reached maximum values at during same cycle, while a/b ratio lower than other concentrations. The net rate (Pn) water use efficiency (WUE) highest ppm. transpiration stomatal conductance significantly those light saturation point apparent quantum their ppm, followed by Additionally, rate, carboxylation efficiency, electron transport activities SOD, CAT, POD, PPO, RuBisCO higher concentrations, recorded 14.54 t·hm −2 .

The increasing use of antibiotics in livestock poses environmental risks, leading to contamination agricultural soils and propagation microbial antibiotic-resistant genes (ARGs). This study examined the impacts wood- manure-derived biochar (BC) on antibiotic residues, ARGs, communities sandy loam clay amended with manure Cynodon dactylon pastures. We hypothesized that BC amendments would influence degradation structure based their physicochemical properties soil types. Our results demonstrated wood reduced concentrations tetracycline sulfonamides, particularly soil, due its larger surface area hydrophobic properties. In contrast, provided additional nutrients supported atmospheric nitrogen-fixing groups, especially while exhibiting variable efficiency reducing residues lower higher ash content. These findings underscore differential each type, emphasizing need for tailored applications type effectively mitigate promote sustainable practices. conclusion, was more effective enhancing health by improving diversity, soils, beneficial nutrient cycling soils.
