Current heavy reliance on agricultural chemicals in US agriculture has raised many environmental and economic concerns. Farmers need to find a way of optimal application of agricultural chemicals. Among agricultural chemicals, nitrogen (N) is the most important and essential for growing crops. In this research, a nitrogen sensor was developed to assess nitrogen status of corn plants and to appl...

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...

The climate changes and increased drought frequency still more frequent in recent periods bring challenges to management with wheat straw remaining the field after harvest its decomposition. experiment carried out 2017–2019 Czech Republic aimed evaluate winter decomposition under different organic mineral nitrogen fertilizing (urea, pig slurry digestate without inhibitors of nitrification (IN))...

Abstract Purpose Charred materials are low in bioavailable nitrogen (N) due to gaseous losses and the formation of recalcitrant structures during pyrolysis. Enriching chars with N from wastewaters offers a possibility upgrade agronomic value manage liquids. For assessing practical feasibility approach, more information on extent retention release loaded is needed. Methods The ammonium-N (NH 4 -...

The use of chemical fertilizers in Thailand increased exponentially by more than 100-fold from 1961 to 2004. Intensification of agricultural production causes several potential risks to water supplies, especially nitrate-nitrogen (NO(3) (-)-N) pollution. Nitrate is considered a potential pollutant because its excess application can move into streams by runoff and into groundwater by leaching. T...
