There are multiple ways that nitrogen (N) use efficiency (NUE) can be assessed, and NUE
indicators are documented in the scientific literature for measuring crop N uptake efficiency …

In temperate grassland, urea has been shown to have lower nitrous oxide emissions
compared to ammonium nitrate‐based fertilizer and is less expensive. However, nitrogen …

A progressive decline in soil fertility in taro (Colocasia esculenta L., Schott) production
systems has contributed to reduced crop productivity and farm profitability, and is recognized …

Global awareness and scrutiny of food production systems, including competition for land
between agriculture and nature-based solutions to climate change, has increased …

Accurate estimates of the quantity and rate of soil nitrogen supply (SNS) are essential to
increase soil and farm N use efficiencies, in particular for soils high in organic matter. The …
