Can stabilized nitrogen fertilizer sources reduce losses through multiple loss pathways?

Using Insurance to Enhance Nitrogen Fertilizer Application Timing to Reduce Nitrogen Losses

Nitrogen applied before planting is more vulnerable to lobs to the environment than nitrogen applied during the gro~ving season, but the growing season application can increase the risk o f lower yields c;iused by adverse weather that prohibits farmers to cornplete N application. An expected utility framework is used to illustrate the potential econo~nic benefit of insurance for :I farmer to re...

Aqueous And Gaseous Nitrogen Losses Induced By Fertilizer Application

Can Watercourse Groups Reduce Nutrient Losses?

Nutrient losses from agricultural land constitute an important part of the total flow of nutrient to lakes and seas in Sweden and the Baltic region. With the EU Directive on water, to be implemented shortly throughout Europe, the expectations on what can be achieved through the decentralisation of various responsibilities from authorities to groups in the civil society is increasing. An importa...

Arbuscular Mycorrhizas Reduce Nitrogen Loss via Leaching

The capacity of mycorrhizal and non-mycorrhizal root systems to reduce nitrate (NO₃⁻) and ammonium (NH₄⁺) loss from soils via leaching was investigated in a microcosm-based study. A mycorrhiza defective tomato mutant and its mycorrhizal wildtype progenitor were used in this experiment in order to avoid the indirect effects of establishing non-mycorrhizal control treatments on soil nitrogen cycl...
