Different fertilization regimes can substantially influence soil fungal community composition, yet fewer studies try to control for the effects of nitrogen input. Here, we investigated impact with equal upon properties and diversity composition in North China Plain a long-term field experiment. Long-term (32 years) were applied amounts nitrogen: no chemical fertilizer or organic manure; only; manure only, and; combination 1/2 manure. Then these four properties, composition. The results...
Results are summarized for the first 15 yr of an eight‐site, long‐term experimental network in China designed to assess sustainability cropping systems environments representing 70% Chinese cropland. Systems were wheat–maize double (two crops per year) at four sites, wheat–rice cropping, rice‐based triple and wheat or maize single cropping. Without fertilizers, yields mainly ≤1 t ha −1 , ≥2 With NPK fertilizer (rates averaging 154, 33, 54 kg crop N, P, K, respectively), ranged from 5 7 6 9 P...
A Gram-stain-positive, spore-forming, obligately anaerobic bacterium, designated LAM201(T), was isolated from sediment samples an alkaline-saline lake located in Daqing oilfield, City, PR China. Cells of strain LAM201(T) were non-motile and straight or spiral rod-shapes. Strain able to utilize glucose, fructose, maltose, trehalose sorbitol as the sole carbon source. Acetic acid, ethanol, iso-butanoic acid iso-valeric main products glucose fermentation. The major fatty acids C(16 : 0) (26.7%)...
Exploration of soil environmental characteristics governing microbial community structure and activity may improve our understanding biogeochemical processes quality. The impact especially organic carbon availability after 15-yr different inorganic fertilizer inputs on bacterial functional metabolic diversity communities were evaluated in a experiment Chang-ping County, Beijing, China. was wheat-maize rotation system which established 1991 including four treatments. These treatments...
Humic acid (HA) is a readily available and low-cost material that used to enhance crop production reduce nitrogen (N) loss. However, there little consensus on the efficacy of different HA components. In current study, soil column experiment was conducted using 15N tracer technique in Dezhou City, Shandong Province, China, compare effects urea with without addition weathered coal-derived components maize yield fate fertilizer-derived N (fertilizer N). The were incorporated into by blending...
Abstract This paper analyzed the compositional and structural changes of humic acid (HA) after combined with phosphate fertilizer (PHA), investigated its effects on growth maize seedlings four concentrations. The results showed that atomic ratios O/C (O + N)/N PHA were significantly lower than those HA, which indicated had poor hydrophilicity compared HA. spectra FTIR NMR suggested relative content carboxyl group in was higher X-ray photoelectron spectroscopy technology amount C–C while C–H...
Humic acids derived from Chinese weathered coal were oxidized with hydrogen peroxide (H2O2) under various conditions, and their chemical composition structure examined. The raw material humic (HA) (OHAs) characterized by elemental analysis ultraviolet visible (UV-Vis), Fourier transform infrared (FTIR), solid-state 13C nuclear magnetic resonance (NMR) spectroscopy. Our results show that aromatic functional groups accounted for more than 70% of the HA OHAs there significant differences in...
Abstract Humic acid (HA) can improve the use efficiency of phosphate fertilizer, although its optimal proportion in fertilizers remains unknown. In this study, we conducted soil column experiments over two growing seasons to compare effects different HA proportions fertilizer on wheat yield and phosphorus uptake, utilization, available phosphorus. At harvest, grain yields were 0.23%–13.21% higher under HA‐enhanced (HAP) compared treatments with conventional (P). Among HAPs, treated HAP 1.0%...
Summary Rhizosphere microbiomes are pivotal for crop fitness, but the principles underlying microbial assembly during root–soil interactions across soils with different nutrient statuses remain elusive. We examined in rhizosphere and bulk of maize plants grown under six long‐term (≥ 29 yr) fertilization experiments three soil types middle temperate to subtropical zones. The communities was primarily driven by deterministic processes. Plant selection interacted regimes shape structure...
Abstract Climate warming and anthropogenic nitrogen (N) loads are two major global change components interactively affecting carbon cycling. However, the effects of N forms amounts on temperature sensitivity (Q 10 ) soil organic matter (SOM) mineralization remain incomplete. With this goal, was sampled after 23 years mineral (or) fertilization, then incubated for one year at 10, 20, 30°C. For first time, we compared four approaches (Equal Equal C, 1‐C pool, 2‐C pool model) to evaluate Q SOM...
The aim of drip fertigation is synchronising the application water and nutrients with crop requirements, maintaining proper concentration distribution nutrient in soil. wetting patterns distributions under have been proved to be closely related strategies. In order find out critical factors that affect different fertigaiton strategies, a computer simulation model HYDRUS2D/3D was used simulate nitrate for various strategies from surface point source. Simulation results were compared observed...
A novel facultatively anaerobic, rod-shaped bacterium, designated LAM1188T, was isolated from the roots of rice (Oryzasativa) in Hubei Province. Cells LAM1188T were Gram-stain-negative and motile. The temperature pH ranges for growth 15–40 °C (optimum: 30 °C) 5–10 7), respectively. strain did not require NaCl but tolerated up to 3.5 % (w/v). Analysis 16S rRNA gene sequence indicated that isolate represented a member genus Chromobacterium , most closely related haemolyticum MDA0585T aquaticum...
A novel aerobic, halotolerant bacterium, designated strain LAM612(T), was isolated from saline-alkaline soil samples Lingxian County, Shandong Province, China. Cells of LAM612(T) were Gram-reaction-positive, endospore-forming, motile and rod-shaped. The optimal temperature pH for growth 35 °C 6.0, respectively.
