Nitrogen Fertilization. A Review of the Risks Associated with the Inefficiency of Its Use and Policy Responses

Nitrogen (N) is a key input to food production. Nearly half of N fertilizer not used by crops and lost into the environment via emission gases or polluting water bodies. It essential achieve production levels, which enable global security, without compromising environmental security. The pollution level expected 2050 projected be 150% higher than in 2010, with agricultural sector accounting for 60% this increase. In paper, we review status from fertilizers worldwide make recommendations address situation. analysis reviews relationship between use, use efficiency, no-point pollution, role farmer management practices, policy approaches diffuse caused fertilization. Several studies show lack information as one main hurdles changes habits. objective study highlight gravity current non-point well need communication effort farmers aware their activity and, therefore, importance practices.
