“…In this study, experimental soil has the C:N varied around 24.0 (organic carbon and N contents were 6.27 %C and 0.27 %N, respectively). In this C:N level, available soil N may be released into soil solution throughout the processes of decomposition rice straw residues or mineralization (Weil and Brady, 2017;Kopittke et al, 2020;Dung et al, 2022). It explained why the organic carbon and available N contents in the treatment that applied 50 kg N ha -1 did not differ significantly compared to the treatment that applied 100 kg N ha -1 .…”

“…Dung et al (2021) reported that applying 50 kg N ha -1 could maintain the number of tillers, rice height, and grain yield of OM5451 and OM6976 compared to the traditional cultivation applied 100 kg N ha -1 . pH is the most important factor in the soil has directly affected the availability of soil nutrients (Weil and Brady, 2017). The change in soil pH is most dependent on the pH of biochar and soil pH.…”

“…However, this application could increase fertilizer costs and high-risk environmental pollution. In addition, rice plant often takes up only 40-50% of N fertilizer applied, and the remaining N fertilizer will be lost through NH3 and N2O volatilization, or runoff to the water environment (Wulf et al, 2002;Choudhury and Khanif, 2004;Weil and Brady, 2017). Soil degradation, which is the loss of soil functions capacity to reduce soil fertility and soil biodiversity, is the most serious problem in the world (Brusseau et al, 2019).…”

Intensive rice cultivation for a long time resulted in increasing soil degradation and less yield. This study aimed to evaluate effects of the combining reducing nitrogen fertilizer (N) with biochar amendment on soil chemical properties, rice growth parameters, and grain yield in the rice cultivation system in the Mekong Delta region, Vietnam (VMD). Field experiment was designed in the split-plot design with two factors, including N fertilizer (main plot) and biochar (sub-plot). Two N fertilizer rates were: (N50)—50 kg N ha–1 and (N100)—100 kg N ha–1, which is the farmer's practice. Biochar was amended with three rates: no applied biochar (B0), 5 t ha–1 (B5), and 10 t ha–1 (B10). The results indicated that reducing N fertilizer by 50% combined 5–10 t biochar ha–1 resulted in maintaining soil pH, soil electrical conductivity, soil organic carbon, cation exchange capacity, and rice biomass. Applying biochar at a rate of 5–10 t ha–1 significantly increased the available N, available P, and rice height compared to the treatment with no applied biochar (B0). Rice yield in the treatments applied with 5–10 t ha–1 was significantly higher than the treatment without the use of biochar by 11.6–14.7%. The findings of this study confirmed that reducing 50% N fertilizer combined with 5 t ha–1 or 10 t ha–1 of biochar could improve soil available N, available P, rice growth, and grain yield in intensive rice cultivation systems in the VMD region.

“…Absolute values of extractable potassium (Table 4) suggested no risk of deficiency, as reported for Pinus radiata [40], but the risk of imbalance between K and Mg should be addressed in future studies in these drier inland regions. Taking into account the critical role that potassium plays in plants' drought resistance [41], increasing the low K/Mg ratio in these dry inland regions could improve umbrella pines' resistance to drought. Among the micronutrients, the levels of iron, copper, zinc and boron were similar to those commonly found in coastal soils, where about 80% of the plots belonged to the medium to very high classes for iron and to the very low class for copper, zinc and boron [38,39].…”

Pinus pinea is widely distributed in the Mediterranean basin. In Portugal, it is predominantly located in the southwestern coastal area. Yet, there are also forest areas of Pinus pinea in inland southern Portugal. Four plots were settled to study the effects of soil chemical characteristics, air temperature and precipitation on Pinus pinea growth. In these plots, stand structure, soil texture, soil organic matter, soil content on macronutrients and micronutrients, air temperature and precipitation were analysed. The results indicate that the greatest growth was achieved in the plots with good availability of nutrients and the highest precipitation, whereas the lowest growth was observed in the plots with the lowest precipitation. There seems to be a trend toward the main limiting factor to Pinus pinea growth being the availability of water.

“…With the increasing rate of global warming, the change in the concentrations of greenhouse gases (GHGs) in the atmosphere is a source of concern in the scientific community (Cao et al, 2005). According to the World Meteorological Organization (WMO, 2018), the concentrations of carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) in the atmosphere have increased by 146 %, 257 %, and 122 %, respectively, since 1750.…”

Abstract. Gradual riparian wetland drying is increasingly sensitive to global warming and contributes to climate change. Riparian wetlands play a significant role in regulating carbon and nitrogen cycles. In this study, we analyzed the emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) from riparian wetlands in the Xilin River basin to understand the role of these ecosystems in greenhouse gas (GHG) emissions. Moreover, the impact of the catchment hydrology and soil property variations on GHG emissions over time and space was evaluated. Our results demonstrate that riparian wetlands emit larger amounts of CO2 (335–2790 mgm-2h-1 in the wet season and 72–387 mgm-2h-1 in the dry season) than CH4 and N2O to the atmosphere due to high plant and soil respiration. The results also reveal clear seasonal variations and spatial patterns along the transects in the longitudinal direction. N2O emissions showed a spatiotemporal pattern similar to that of CO2 emissions. Near-stream sites were the only sources of CH4 emissions, while the other sites served as sinks for these emissions. Soil moisture content and soil temperature were the essential factors controlling GHG emissions, and abundant aboveground biomass promoted the CO2, CH4, and N2O emissions. Moreover, compared to different types of grasslands, riparian wetlands were the potential hotspots of GHG emissions in the Inner Mongolian region. Degradation of downstream wetlands has reduced the soil carbon pool by approximately 60 %, decreased CO2 emissions by approximately 35 %, and converted the wetland from a CH4 and N2O source to a sink. Our study showed that anthropogenic activities have extensively changed the hydrological characteristics of the riparian wetlands and might accelerate carbon loss, which could further affect GHG emissions.
