Little has been reported on the effects of long-term fertilization rhizosphere soil microbial diversity. Here, we investigated continuous nitrogen (N) diversity and composition bacteria using data from a 10-year field experiment with five N application rates (0, 120, 180, 240, 360 kg hm-2). The results revealed varying degrees reduction in numbers bacterial operational taxonomic units (OTUs) response to different rates. highest wheat yield number proprietary OTUs were found input 180 hm-2....
Although conservation tillage has been widely implemented to address the challenge improve crop yield and soil quality with fewer environmental costs, its long-term effects on yields stoichiometry balance remain uncertain. Here, four different (17-year) practices (conventional (CT), deep scarification (DS), no (NT), ridge (RT)) were conducted in northern China evaluate their yield, nutrients, C sequestration, stoichiometry. The (DS, NT, RT) increased recent 5-year average by 12.2 %-20.1 %...
Inadequate water and nitrogen (N) supplies can limit the productivity of maize. Climate change will likely increase drought in many regions on a global scale. The determination N fertilizer rates under field conditions be critical toward reduction agricultural risk. For this study, drought-resistant/sensitive cultivars were selected as experimental samples. Our results revealed that stress reduced relative content (RWC) leaves, which resulted leaf curling, while decreasing photosynthesis...
The performance of fertilizers may differ significantly in different soils. Here, we quantify effects various phosphorus (P) on maize yield and P uptake soils with pH values, using a pot experiment. Five were used; monoammonium phosphate (MAP), diammonium (DAP), calcium superphosphate (CSP), magnesium (CMP) and, ammonium polyphosphate (APP). Two neutral fluvo-aquic soil (pH 7.2) acidic yellow cinnamon 5.0). Generally, restricted the root activity, dry matter accumulation, uptake, maize....
Abstract Nitrated phenolic compounds in the atmosphere are receiving increasing attention due to their light absorption and biological toxicity. In this study, particulate, gaseous, cloud water samples were simultaneously collected during events at summit of Mount Tai northern China spring, summer, winter contents 11 nitrated determined. The seasonal average concentrations total particles range 7.3–27.1 ng m −3 , a little lower than those measured gas‐phase (18.3–70.6 ). Their levels...
The stay-green leaf phenotype is typically associated with increased yields and improved stress resistance in maize breeding, due to higher nitrogen (N) nutrient levels that prolong greenness. application of N fertilizer can regulate the status plants, furthermore, impact photosynthetic rates leaves at productive stage; however, deficiencies excesses will reduce yields. Consequently, it necessary develop management strategies for different types maize. For this study, senescent cultivar...
The contributions of the different leaf layers to maize yields identified as middle > lower upper leaf, where vertical photosynthetically active radiation (PAR) in canopy gradually decreases. We hypothesized that allocation more PAR and nitrogen (N) highest contributing leaves will would be beneficial for higher N use efficiencies. application rate plant density effectively regulated light distribution. evaluated interactive effects on agronomic ecophysiological characteristics at...
Understanding the role of soil organic matter (SOM) in quality and subsequent crop yield input requirements is useful for agricultural sustainability. SOM widely considered to affect a wide range properties, however, great uncertainty still remains identifying relationships between due difficulty separating effect from other yield-limiting factors. Based on 543 on-farm experiments, where paired treatments with without NPK fertilizer were conducted during 2005–2009, we quantified inherent...

Abstract The maintenance and accumulation of soil organic carbon (SOC) in agricultural systems is critical to food security climate change, but information about the dynamic trend efficiency SOC sequestration still limited, particularly under long‐term fertilizations. In a typical Purpli‐Udic Cambosols subtropical monsoon southwestern China this study thus estimated dynamic, after 22‐year (1991–2013) inorganic and/or Nine fertilizations rice–wheat system were examined: control (no...
It is important to quantify nutrient requirements and optimize fertilization improve peanut yield fertilizer use efficiency. In this study, a multi-site field trial was conducted from 2020 2021 in the North China Plain estimate nitrogen (N), phosphorus (P), potassium (K) uptake of peanuts, evaluate effects recommendations regional mean optimal rate (RMOR) on dry matter, pod yield, uptake, Results show that compared with farmer practice (FP), (OPT) based RMOR increased matter by 6.6% 10.9%....
Potassium (K) is a critical plant nutrient that determines quality in myriad of crops and increases production yields. However, excessive application various types K fertilizers can decrease both the food yields, which translates as economic losses safety issues. The objectives this study were to 1) elucidate impacts different rates on garlic, with aim identify optimal most economical fertilizer dosage 2) compare effects applying two common (KCl 2 SO 4 ) determine combination. From 2018...
With the growth of industry, extensive use lead, and urban expansion in Northwestern Valley Cities (NVC) China, there is probable reason for presuming an increasing risk lead exposure. However, little known about exposure children less than 6 years old NVC. As a first investigation, this study uses survey to systematically determine influences various factors within family environment, parents’ background, children’s behavior, mother’s behavior during pregnancy, parental perception blood...
Soil organic carbon (SOC) sequestration impacts on food security and climate change may be affected by soil microbes in fertilized croplands. A 12-year field experiment under the rice–wheat system was used to evaluate effect of long-term fertilization SOC accumulation, culturable microbes, their interaction purple paddy soil. Results showed that varied fertilizations resulted a significant increase content stock plow layer, as well rise populations major including bacteria, actinomycetes,...

Abstract The accurate and nondestructive assessment of leaf nitrogen (N) is very important for N management in winter wheat fields. Mobile phones are now being used as an additional diagnostic tool. To overcome the drawbacks traditional digital camera methods, a histogram-based method was proposed compared with methods. Here, field level six different cultivars assessed to obtain canopy images, content, yield. stability accuracy index histogram mean value images were based on their...
Conservation tillage is widely believed to promote soil aggregate stability and carbon (C) nitrogen (N) sequestration, but the underlying mechanisms remain unclear. Here, we collected samples from an 18-year experiment in northern China that included conventional with straw removal (CT), deep scarification mulching (DS), no-tillage (NT) models. The results showed NT DS increased total organic (SOC) N by 9.3–16.4% 10.8–25.8%, respectively, addition increasing weight proportion of...
