Abstract Soil physical properties and soil organic carbon (SOC) are considered as important factors of quality. Arable land, grassland, forest land coexist in the saline-alkali reclamation area Yellow River Delta (YRD), China. Such different uses strongly influence services ecosystem to induce degradation loss. The objective this study is evaluate variation texture, aggregates stability, affected by uses. For each use unit, we collected samples from five replicated plots “S” shape profiles...
Enhancing nitrogen (N) use efficiency (NUE) and reducing urea N losses are major challenges in ensuring sustainable agriculture. The aim of this study was to investigate the effect humic acid on losses, soil microbial nutrient balance NUE through leaching experiments, incubation experiments field maize-wheat rotation. We set up four gradients (240 kg hm−2, 216 192 168 hm−2) two fertilizer types (urea urea) make five treatments, with no application as control. results showed that reduced by...
To improve the availability of inorganic phosphorus (P) in soil, we investigated role three macromolecular organic acids (MOAs), including fulvic acid (FA), polyaspartic (PA), and tannic (TA), reducing fixation P fertilizer soil. AlPO4, FePO4, Ca8H2(PO4)6·5H2O crystals were chosen as insoluble phosphate representatives soil to simulate solubilization process by MOAs. The microstructural physicochemical properties determined scanning electron microscopy (SEM), Fourier-transform infrared...
With the random discharging of industrial and agricultural wastewater, a large amount cadmium (Cd) has accumulated in soil, which seriously affects growth crops people’s food safety. In this study, alfalfa was used as material for studying effects inoculation Piriformospora indica (P. indica) on photosynthesis, osmoregulatory substances, antioxidant enzymes seedlings at different Cd concentrations (0, 5, 10, 30, 50, 100 mg/L) through hydroponic experiments. The results showed that with...
Soil carbon (C), nitrogen (N) and phosphorus (P) are important soil properties linked to nutrient limitation plant productivity in terrestrial ecosystems. Up 90% of the Yellow River Delta (YRD), China has been affected by salination due groundwater overdraft, improper irrigation, land use cover change. The objective this study is evaluate impact different communities on quality a saline-alkaline system YRD. We investigated vertical distribution seasonal variation C, N, P, C:N ratio choosing...
The ecological impact of nitrogen (N) deposition has gained significance since the advent industrial revolution. Although numerous studies have examined N on soil organic carbon (SOC), certain arid and barren rocky mountainous regions, which experience more pronounced limitations, been overlooked. This study was conducted in Yimeng Mountains, examining eight treatments created by four addition levels (0 kg ha−1 yr−1, 50 100 yr−1 200 yr−1) two tree species (Quercus acutissima Carruth. Pinus...
The irrational land use patterns in the Yellow River Delta (YRD) have resulted an imbalance ecological stoichiometry, leading to secondary salinization and soil degradation. However, there is limited knowledge about long-term response of enzyme stoichiometry use. This hampers our ability optimize YRD alleviate nutrient limitation thus promote stoichiometric balance. We investigated carbon (C), nitrogen (N), phosphorus (P) three (Alfalfa artificial grassland, AG; wheat–maize rotation field,...
Abstract The reclamation area of the Chinese Yellow River Delta (YRD) has experienced frequent land use changes in recent decades. consequence such on stocks and allocation ecosystem‐scale carbon is not known. Here, we assessed four representative uses YRD area: (1) purple alfalfa (LAL), (2) reed Aeluropus littoralis (RAE), (3) cotton (ECO), (4) tamarisk (CTA). results showed that overall stocks, aboveground, litter, roots, soil were notably different among uses. native CTA had largest stock...
The conversion of land uses was frequent in the saline-alkali reclamation region Yellow River Delta (YRD), China. However, knowledge combined effects carbon (C), nitrogen (N), and phosphorus (P) stoichiometry for soil enzyme under different use patterns is limited. We investigated C, N, P extracellular activities three representative (Alfalfa artificial grassland, AG; wheat-maize rotation field, WM; native PC). results showed that average AG, WM, PC 31.32: 1.74: 1, 34.05: 1.46: 26.58: 1.14:...
