N uptake efficiency
Web16 okt. 2024 · The nitrogen use efficiency is the product of nitrogen uptake efficiency and nitrogen utilization efficiency, it varies from 30.2 to 53.2%. Nitrogen losses are too high, due to excess amount, low plant population, poor application methods etc., which can go up to 70% of total available nitrogen. Web7 apr. 2024 · Enhanced efficiency N fertilisers (EENF) including DMPP-urea (Entec®) can lower nitrous oxide emissions compared to urea, but evidence for higher agronomic efficacy—the ability to attain optimum grain yields at lower N application rates than standard urea fertiliser—is lacking. Three multi-N fertiliser rate trials were established in the …
