The intensity of milk production from pasture based dairy farming systems is often related to nitrogen (N) losses. This …

to the fossil fuels consumption (EF effect), (ii) the changes in fossil fuels consumption compared to the use of Nitrogen … in agriculture (FN effect), (iii) the change in use of Nitrogen in agriculture per ha of utilized agricultural area (NA … Netherlands, Belgium and Luxemburg respectively), which means that the use of Nitrogen per cultivated area is an important factor …

Winter legumes can substitute for applied nitrogen fertilization of corn. Stochastic dominance was used to order net … revenues from legume and applied nitrogen alternatives. Stochastic dominance orderings indicate that systems combining vetch … with low applied nitrogen fertilization (50 and 100 pounds/acre, respectively) were risk inefficient. By contrast, vetch …

Potential benefits of variable rate nitrogen application are illustrated and information needs identified. Lower costs …

This paper identifies optimal combinations of nitrogen in the form of urea, fresh litter and composted litter for rice … poultry litter and urea nitrogen depends on such factors as soil fertility, the yield response to litter application and the … relative prices of nitrogen and litter. The use of litter is more economical at high target yields than at low target yields. …

Soil acidity and cotton yields are influenced by cover crop, nitrogen, and tillage method. Applying half the … recommended lime rate may be possible without reducing cotton yields. Using a nitrogen intensive cover crop and applying less … nitrogen should mitigate the effects on soil acidity and yields. …

This paper deals with symbolic communication between the doses of nitrogen and mass content of gluten in wheat grain …
