in order to evaluate the efficiency of plant growth promoting rhizobacteria (pgpr) plus nitrogen and phosphorous chemical fertilizers on relative agronomic efficiency of p and n fertilizers and some agronomic parameters of wheat (triticum aestivum l.) cultivar n-80-19, an experiment was conducted at sari agricultural sciences and natural resources university during growing season of 2008-2009. ...

Use of enhanced-efficiency N fertilizers (EENFs) in row crop agriculture has not been well studied despite increasing interest in these N sources to increase crop yield while decreasing N loss. A field study was conducted in Central Alabama from 2009 to 2011 to compare EENFs to standard N sources in a high-residue conservation cotton production system. Nitrogen fertilizers evaluated were: urea;...

N2-fixing methanotrophs play an important role in the methane-nitrogen cycle in rice paddies. We report here the draft genome sequence of Methylosinus sp. strain 3S-1 isolated from rice root in a paddy field without N fertilizer input.

The utilization of nano-sized nitrogen (N) and zinc (Zn) fertilizers through foliar application has gained considerable attention in agricultural research. This study focuses on investigating the effects such applications soil properties, including both chemical biological aspects, after harvest mustard (Brassica juncea L.). field experiment was carried out during October to March 2022 season a...

The aim of this study was to evaluate the long-term (16-years) nitrogenefficiency after the application of organic and mineral fertilizers at two sitesLukavec (S1) and Suchdol (S2) with different soil and climatic conditions in theCzech Republic (Central Europe) and to determine grain yield and nitrogen contentwith regard to the requirements of protein content for baking quality of wheat.After ...

In order to study of the effect of seed inoculation with PGPR on nitrogen and phosphorus use efficiency of spring wheat in different levels of nitrogen and phosphorus fertilizers, an experimental was conducted at the Research Farm of Mohageh Ardabili University, Ardabil, Iran during 2012 year. The combination of nitrogen fertilizer in three levels (0, 40 and 80 kg N/ha as urea) and phosphorus f...

Denitrification woodchip bioreactor two-phase column study: Evaluation of nitrate removal at various hydraulic retention times and effect of temperature on denitrification rates" (2012). The transport of nitrate to surface waters is an increasing concern in United States and throughout the world. Causal linkages have been established between nutrient loading from the Mississippi River Basin wat...
