Does a Japan-Korea FTA Increase Nitrogen Pollution from Agriculture?: A Nitrogen Balance with the GTAP Model

~esigning a Long-term Nitrogen Balance Experiment

The answers to many agronomic questions can only be obtained from long-term experiments in which the evolution of responses to experimental treatments can be observed for several years. In this paper, we describe our experience in designing and running an experiment set up to study changes in the nitrogen balance associated with a continual rotation of summer and winter crops grown on a Tokomar...

Nitrogen balance after injuries.

An increased excretion of nitrogen after injuries in experimental animals and in man was described by Cuthbertson (1930). In a series of papers he and his colleagues discussed and explored almost all the facets of this phenomenon which have since been studied (see, e.g., Cuthbertson, 1929, 1930, 1936, 1942; Cuthbertson & Tompsett, 1935 ; Cuthbertson, McGirr & Robertson, 1939). He investigated t...

management strategies to increase nitrogen use efficiency (nue) in agriculture

use of nitrogen fertilizers has contributed much to the remarkable increase in food production that has occurred during the past 50 years. however, environmental and economic challenges due to nitrogen application in agricultural have increased regard to nitrogen use efficiency (nue). studies conducted around the world shows that only half of nitrogen fertilizer inputs is taken up by crops. unf...

How Will the China-Japan-Korea FTA Affect the Inward FDI to Korea?

The Nitrogen Footprint Tool Network: A Multi-Institution Program To Reduce Nitrogen Pollution

Anthropogenic sources of reactive nitrogen have local and global impacts on air and water quality and detrimental effects on human and ecosystem health. This article uses the Nitrogen Footprint Tool (NFT) to determine the amount of nitrogen (N) released as a result of institutional consumption. The sectors accounted for include food (consumption and upstream production), energy, transportation,...
