Abstract:

The soil nitrogen cycle and the dynamics of its transformation are closely related to the functioning of the forest ecosystem. This cycle, and the availability of nitrogen as a necessary nutrient in the soil, can be influenced by the process of thinning. The aim of this study is to describe the impact of silvicultural measures on the content of ammonium and nitrate nitrogen in forest soil. Attention is paid to the organic (spruce treatments) and organomineral horizon (beech treatments) in which the transformation of soil nitrogen is most pronounced.

The effect of water supply during grain growth on grain nitrogen concentration (GNC) and grain nitrogen yield (GNY) of winter wheat (<I>Triticum aestivum</I> L.) was studied in the field experiment on fertile loamy-clay soil in years 2004–2007. The water regime was differentiated using mobile rain shelter (water shortage, treatment S) and drip irrigation (ample water supply, treatment W); rain-fed crop served as the control treatment (R). Wheat was grown without addition of nitrogen and with 200 kg N/ha (N0 and N1, resp.). The effect of water supply on GNC was highly significant (&

Abstract:

Nitrogen-based fertilizers are widely consumed to increase productivity since they play an essential role in plant growth. Common commercial fertilizers contain “mobile” nitrogens that can be easily transformed into other nitrogen compounds. The approach method to decrease nitrogen loss is called controlled-release fertilizer (CRF), which is done by modifying fertilizers with coating inhibitors such as polyurethane to provide surface resistance that inhibits nutrient release. Multilayer coating is one of the alternatives to minimize the risk of losing nitrogen content from granular fertilizer.

Abstract:

The effect of nitrogen fertilization on root length (RL) distribution of winter wheat (Triticum aestivum L.) was investigated.

Two (N0, N1) and three (N0, N1, N2) treatments, unfertilized (N0), fertilized with 100 kg (N1) and 200 kg N/ha (N2) were studied in 1996&ndash;2000 and 2001&ndash;2003, respectively.

Weeds cause crop loss indirectly by reducing the quantity of resources available for growth.

Soybean is one of the most traded products. Naturally, soy fixes nitrogen through biological symbiosis. Its cultivation transforms natural inert atomic nitrogen into its reactive forms. The advancement of soybean can have environmental impacts, both locally and globally. This study estimated nitrogen flows and their use efficiency in the Brazilian soybean production chain applying material flow analysis. We innovate proposing a new indicator to estimate the “cascade effect of nitrogen” in a framework of 12 years (2007 to 2019). We hypothesized that it is capable to show accumulated nitrogen em

Abstract:

The influence o f landscape position on the dynamics of N in the soil-plant system has not been adequately studied. Our aim with this study on a predominantly Black Chernozem soil was to evaluate the effect of slope position (upper vs. lower) and N fertilizer application (none vs. 60 kg N ha-1) on soil and wheat (Triticum aestivum L.) N through the growing season. Landscape position had a dominant effect on soil NO3− and soluble organic N (SON) concentrations, especially in the surface 15 cm. These pools of soil N and net N mineralization were greater at the lower than at the upper slope posit

Abstract:

In order to clarify the response characteristics of tillering and nitrogen (N) uptake and utilization under micro-nano bubble aeration irrigation and nitrogen fertilizer level, the nitrogen uptake and utilization characteristics, tillering and yield of early rice under different irrigation methods and nitrogen levels were investigated. The results showed that micro-nano bubble aerated irrigation and nitrogen fertilizer have substantial influence on tillering of early rice, and the effect of N fertilizer was greater than the effect of oxygen. Nitrogen accumulation increased by 6.75–10.79% in mi

To reveal the characteristics of soil organic nitrogen components under different long-term fertilization methods in paddy fields, 7 typical paddy fields in the Yanbian Korean Autonomous Prefecture of Jilin Province were selected, and soil samples were collected from 0 to 10 cm and 10 to 20 cm. The samples were analyzed for available nitrogen, total nitrogen and inorganic nitrogen content and each component of organic nitrogen. The results showed that soil nitrogen decreased with increasing soil depth in the soil profile. Different fertilization methods had a significant or greater effect on t

We examined the effects of nitrogen and phosphorus fertilizer and paclobutrazol on flowering precocity and abundance in Eucalyptus nitens Deane & Maid. Trials to test these effects consisted of a factorial nitrogen by phosphorus experiment replicated on two sites and factorial nitrogen by paclobutrazol experiments conducted separately on reproductively immature and reproductively mature trees. The increase in tree size due to nitrogen fertilization increased the occurrence and abundance of precocious flower buds. However, the increase in tree size alone could not account for the nitrogen e

In this study, PVC soil column experiments and field experiments were used to evaluate the interception effect of soil amendments produced by green wastes on nitrogen and phosphorus leaching. The pH value, EC value, the nutrient contents of ammonium nitrogen (NH4 +-N), nitrate nitrogen (NO3 −-N), total nitrogen (TN), and available phosphorus (AP) in different soil layers and leaching solu

Abstract:

The intercropping of nitrogen-fixing and non-nitrogen-fixing tree species changed the availability of soil nitrogen and soil microbial community structure and then affected the regulation process of soil carbon and nitrogen cycle by microorganisms in an artificial forest. However, there is no consensus on the effect of soil nitrogen on soil microorganisms. In this study, the intercropping of mulberry and twigs was completed through pot experiments. Total carbon, total nitrogen, and total phosphorus in the rhizosphere soil were determined, and the composition and structure of the soil microbial

The experiments of high nitrogen steels refining have been researched with high pressure and bottom-blown nitrogen in laboratory. We can gain high nitrogen nickel-free stainless steels that its content is more than 0.9%. The research indicates that the temperature influences nitrogen content greatly in the processes of smelting and concreting. The results are shown that saturated nitrogen content in steel increased slightly. When the temperature is as high as 1913K, the nitrogen content can reach 1.191%.

Abstract:

We have observed a strong electrorheologial (ER) effect of a suspension of fine aluminum particles in liquid nitrogen. The particles have diameter ~ 10μm and an insulate surface. In an ac field, aluminum particles quickly form chains across the two electrodes. The chains vibrate vigorously as the liquid nitrogen has a constant random flow motion caused by bubbles. In addition to low temperature, liquid nitrogen has extremely low viscosity, and low conductivity. These special properties enable us to observe several interesting phenomena which are absent in ER fluids at room temperature. We have
