In this study, the optimal operation factors for struvite crystallization for removing and recovering nitrogen and phosphorus from anaerobic digestive fluid of swine manure containing highly concentra...
Forests occupy one third of the world’s land area and govern carbon (C) transfers and influence nitrogen (N) content in the biosphere. Afforestation leads to soil changes of specific dynamics, often a...
The effects of highly volatile organochlorine solvents (1,1,1-trichloroethane, TCET; trichloroethylene, TCE; and tetrachloroethylene, PCE) on soil nitrogen cycle and microbial counts were investigated...
The content of nitrate or mineral nitrogen (Nmin = N-NO3 – + N-NH4 + ) in soil in autumn is recognized as the indicator of potential risk of N leaching during winter
This study was aimed at monitoring the relative and absolute stand heterogeneity of total carbon, total nitrogen and C/N ratio in Ah-Ae-Btg-Bt horizons of Gleyic Luvisol on one mountain meadow divided...
Time of planting plays a critical role in nitrogen (N) uptake by rye cover crop (CC). Even a few days of delay in planting can severely decrease CC performance. Evaluating the amount of N accumulation...
The application rate of a nitrogen fertiliser is one of the most important factors that affect the nitrous oxide (N2O) flux. Calk ammonium nitrate with 27% nitrogen content was spread by a fertiliser ...
A field study was conducted during 2008 and 2009 at El-Khattara farm station, Zagazig Uni-versity, Sharkyia, Egypt (30°36' N, 32°15' E) to determine the effect of three N rates (214, 273, and 333 kg N...
Effects of different levels of compost application on the amounts and percentage distribution of organic N forms in whole soils and particle size fractions were investigated. Soil samples were collect...
Assessment of soil quality is an invaluable tool in determining the sustainability and environmental impact of agricultural ecosystems. The study was conducted to assess the quality of the soils under...
A laboratory incubation experiment was carried out for 85 days to monitor the N mineralization during the decomposition of 15N labeled wheat and rice straws incorporated at 5 g kg-1 soil at varying te...
In this study, 15N-labeled organic materials were used to evaluate the nitrogen (N) dynamics associated with the application of organic materials to paddy fields. The decomposition of three types of o...
The nature of soil type is an important factor in the bioaccumulation of substances in plants. Application of nitrogen fertilizer is a common practice in vegetable farming. This study was therefore co...
Field experiments were conducted in 2006 to investigate the impacts of modified rice cultivation systems on: grain yield, N uptake, ammonia volatilization from rice soil and N use efficiency (ANUE, ag...
This research was carried out in order to determine the effects of nitrogen and phosphorus fertilization on yield, some fruit characteristics, hormone concentrations, and alternate bearing in pistachi...
