Widespread soil acidification due to atmospheric acid deposition and agricultural fertilization may greatly accelerate carbonate dissolution CO2 release. However, date, few studies have addressed these processes. Here, we use meta-analysis nationwide-survey datasets investigate changes in inorganic carbon (SIC) stocks China. We observe an overall decrease SIC topsoil (0-30 cm) (11.33 g C m-2 yr-1) from the 1980s 2010s. Total decreased by ∼8.99 ± 2.24% (1.37 0.37 Pg C). The average losses...
Compared to fluctuating soil water (FW) conditions, stable (SW) can increase plant use efficiency (WUE) and improve crop growth aboveground yield. It is unknown, however, how affect root vegetables. Here, the effects of SW FW were studied on cherry radish in a pot experiment, using negative pressure irrigation conventional irrigation, respectively. The assessed included agronomic parameters, physiological indices, yield, quality WUE radish. Results showed that under similarly average...
Strawberry (Fragaria × ananassa Duch.) has a unique flavor and nutritional value. To investigate the effects of deficit irrigation on growth, yield, quality, water use efficiency strawberries, “Zhangji” “Hongyan” varieties were assessed in greenhouse. Four levels set as 95% (CK), 75% (LS), 55% (MS), 35% (±5%) (SS) field capacity, respectively. Five successive plant growth stages analyzed. The results indicate that plants’ daily consumption intensity, well fruit yield titratable acidity,...
The pressure of the water supply is controlled to a negative value relying on soil matric suction and called negative‐pressure irrigation (NPI), subsurface method used improve use efficiency; however, impacts initial conditions emitter hydraulic conductivity movement under NPI remain unknown. To study effects management parameters NPI, 300 scenarios using different textures, potentials, conductivities, inside time were simulated Hydrus-2D software package. these variables analyzed following...
This study examined the effect of different negative pressures and soil textures on water salt movement to improve efficiency pressure irrigation (NPI). Four varying fineness (Loamy Sand, Loam, Silty Sandy Loam) three values (0, –5, –10 kPa) were used. As time increased, wetting front speeds decreased, as size decreased. Coarse soils had smallest under greater pressure. Next, infiltration rate decreased coarse lowest average Finally, content increased with distance from emitter Further,...
Uneven rainfall, in the context of global warming, can cause soil moisture fluctuations (SMFs) that harm crop growth, and it is not yet known whether nitrogen (N) mitigate caused by a strong SMF. This paper uses okra as test subject sets three SMFs 45–55% FC (W1), 35–65% (W2), 25–75% (W3) N applications 0 kg hm−2 (N0), 110 (N1), 330 (N2) to investigate effects SMF application on physiological biochemical aspects okra. The results demonstrated exhibited highest values stem diameter, number...
Weaker temporal variation of soil moisture can improve crop water use efficiency (WUE), but its physiological mechanism was still unclear. To explore the mechanism, an organized experiment conducted in Beijing from June to September. From jointing stage maturity maize, stable (SSM) and fluctuating (FSM) were established with Pressure Potential Difference-Crop Initiate Drawing Water (PCI) manual irrigation (MI), respectively, SSM maize WUE. Among them, PCI treatments set 3 pressure...
Reliable prediction of soil organic carbon (SOC) density and sequestration potential (CSP) plays an important role in the atmospheric dioxide budget. This study evaluated temporal spatial variation topsoil SOC CSP 21 groups across Hebei Province, China, using data collected during second national survey 1980s recent inventory 2010. The can be estimated by method that saturated content subtracts actual associated with clay silt. Overall, most increased from to 2010 varied between different...
Effects of continuous negative pressure water supply on consumption, growth and development, as well physiological mechanism quality Capsicum annuum L. were investigated in this paper. Meanwhile, the optimal conditions for C. screened out to achieve goals conservation, high yield quality, thus providing theoretical foundation its field production. The pot experiment within greenhouse was utilized; adopted; four treatments, artificial watering (CK), –5 kPa (T1), –10 (T2), –15 (T3) set; daily...
The study investigated the response to five levels of potassium (K) fertilizer addition on tomato (Solanum lycopersicum L.) performance and soil bacterial communities by negative pressure irrigation (NPI) over two consecutive years. application K fertilization positively affected under NPI, as indicated increased yield, quality, growth, nutrients' contents compared with no treatment. High-throughput sequencing rhizosphere revealed that additions significantly in diversity indices according...
This study explored the physiological and molecular mechanisms of yield increase in maize under stable soil water content (SW) conditions. Results showed that SW conditions, corn increased by 38.72 44.09% 2019 2020, respectively. Further, it was found dry matter accumulation, economic coefficient photosynthetic rate also 31.24 25.67%, 5.45 15.38% as well 29.60 31.83% 2020 However, results both activity antioxidant enzymes osmotic adjustment substances decreased When compared with moisture...
It is important to calibrate the potential evapotranspiration measured by Hargreaves method (ET0,HG) using Penman-Monteith (ET0,PM). However, substantial temporal variations in calibration coefficients (ET0 ratio two methods) have not been considered spatial analysis of coefficients. The objectives this study were investigate spatiotemporal distribution coefficient on scale Mainland China and compare accuracy calibrated ET0,HG with three alternative methods including over space or time. One...
