19 Mar Enhanced efficiency fertilizers cut nitrous oxide emissions in spring wheat

Posted at 14:59h in Soils and Fertility

Nitrification-inhibitor products – either alone or in combination with an urease inhibitor – reduced N2O emissions by 38% to 43% compared to untreated urea in spring wheat in southern Manitoba. However, there were few yield or grain protein benefits to using the EEFs products. Environment and...

24 Oct Reduced emissions with EEF fertilizer but little agronomic benefit

Posted at 19:28h in Soils and Fertility

At 4 of 6 site-years, SuperU reduced N2O emissions by 30% to 57% compared to conventional urea, for all placement methods. However, there was no yield or economic benefit derived from the use of the enhanced efficiency fertilizer (EEF). Nitrous oxide (N2O) is a major greenhouse...

22 Sep EEFs did not reduce nitrous oxide emissions in winter wheat

Posted at 17:36h in Soils and Fertility

Three enhanced efficiency nitrogen (N) fertilizers applied at seeding or in split applications between fall and spring did not reduce nitrous oxide emissions compared to conventional urea or UAN fertilizer when applied at 80% of recommended rate. A split application of 30% N at seeding...
