The soil microbial community is critically important in plant nutrition and health. However, this extremely sensitive to various environmental conditions. A pot experiment was conducted during the wheat seedling stage better understand influences of coupled application nitrogen (N) decomposing inoculants (MDI) on bacteria under different water regimes. There were two levels six fertilization. results reveal that stress increased relative abundance Acidobacteria decreased Firmicutes Proteobacteria. 250 kg N ha−1 altered diversity bacterial but nitrifying bacteria. Nitrous oxide (N2O) carbon dioxide (CO2) emissions negatively correlated with Myxococcota Methylomirabilota while positively Patescibacteria. These gases also bacteria, correlation more significant full irrigation regime. findings indicate MDI does not substantially influence its relationship greenhouse gas emission at would mainly depend rational control amount applied.

Groundwater drought is distinctive comparing with other droughts, featuring high concealment, long duration, and obvious hysteresis. It may have significant negative effects on agriculture, eco-environment, social economy sectors. Therefore, investigating the temporal spatial characteristics of groundwater its driving factors meaningful for monitoring assessing risks shortage. In this study, a index based storage anomalies (GWSAs) derived from GRACE satellites was developed to detect analyze events. The spatiotemporal variations trends historical droughts 2002 2021 in North China Plain were evaluated. addition, correlations between meteorological agricultural analyzed by detrended cross-correlation analysis. results indicated that (1) standardized anomaly (SGSAI) could better identify characterize eliminating heterogeneity GWSAs; (2) 2021, intensity, frequency, area showed an increasing trend; (3) had hysteresis (>9 months) correlation increased, while relationship decreased; (4) long-term overexploitation resources might be main factor exacerbating area.

The North China Plain is a crucial agricultural region in China, but irregular precipitation patterns have led to significant water shortages. To address this, analyzing the high-resolution dynamics of root-zone soil moisture transport essential for optimizing irrigation strategies and improving resource efficiency. Richards equation robust model describing across multiple layers, yet its application at large spatial scales hindered by sensitivity boundary conditions parameters. This study introduces novel approach that, first time, employs continuous time series near-surface as upper condition estimate Plain, thus enabling large-scale application. Singular spectrum analysis (SSA) was applied reconstruct site-specific series, filling missing singular values. Leveraging observational data from 617 monitoring sites covariates, we developed machine learning 1 km resolution. high-resolution, then served equation, facilitating estimation region. results indicated that achieved correlation coefficient (R) 0.92 estimating moisture. Analysis covariates showed atmospheric forcing factors, particularly temperature evaporation, had most substantial impact on performance, followed static factors such latitude, longitude, texture. With moisture, method accurately predicted multi-layer demonstrated applicability use. yielded R values 0.97, 0.78, 0.618, 0.43, with RMSEs 0.024, 0.06, 0.08, 0.11, respectively, layers depths 10 cm, 20 40 100 cm Plain.

Drip fertigation (DF) can improve yield, water use efficiency (WUE), and nitrogen (NUE, grain production per unit of the sum soil inherent mineral N fertilizer N), as well reduce risk environmental pollution compared with flood irrigation broadcast (FB). Previously, we showed that DF enhanced response yield to topdressing rate (NTR), but underlying mechanisms associated supply, root architecture, uptake remain unclear. We conducted a field experiment by testing six treatments (no applied, NTRs 0, 40, 80, 120, 160 kg ha−1, denoted N0, T0, T40, T80, T120, T160, respectively) under FB from 2021 2023. Compared FB, NUE WUE were 4.8–4.9% 10.0–10.5% higher DF. The was due an improvement in (6.1–7.7%) resulting aboveground (AGN). greater AGN attributed availability at depth 0–40 cm. decreased residual NO3−-N 40–200 cm increased In addition, combined T80 achieved high length density, surface dry weight density improved WUE. efficient utilization N, NTR threshold 61.75–119.50 which conditions similar those experimental site. Our results provide reference for high-efficiency usage irrigated winter wheat North China.

Long-term rotary tillage limit water infiltration and crop productivity in North China Plain (NCP). The practice of subsoiling to fracture plow pans has made beneficial impacts on soil surface structure infiltration. Further, appropriate irrigation method coupled with regime can improve condition. A three-year field trial (2020–2023) was carried out assess the effects winter wheat evapotranspiration (ET), grain yield (GY), (WP), partial factor from applied nitrogen (PPFN), economic analysis. three regimes were irrigated when moisture levels decreased 70%, 60% 50% capacity (referred as H, M L) two methods drip (SDI) micro-sprinkler (MSI). traditional flood 70% filed CK. results showed optimizing significantly influenced ET, GY, WP, PPFN, net incomes. As amount increased, ET first increased while incomes then slightly decreased. Based average, maximum GY 9454 kg ha−1 income 11089 yuan achieved SDI-M, which had WP 2.3 m−3 PPFN 39.4 kg−1. At same time, SDI-M did not result much increase (average 405.1 mm seasons). Considering comprehensively incomes, irrigate decreases by optimal strategy all aspects. These will provide a scientific reference for management NCP, well similar production areas worldwide.
