Soil properties and weather conditions are known to affect soil N availability and plant N
uptake; however, studies examining N response as affected by soil and weather sometimes …

Improved prediction of optimal N fertilizer rates for corn (Zea mays L.) can reduce N losses
and increase profits. We tested the ability of the Agricultural Production Systems sIMulator …

Nitrogen (N) fertilizer recommendation tools could be improved for estimating corn (Zea
mays L.) N needs by incorporating site-specific soil and weather information. However, an …

Abstract Maize (Zea Mays L.) yield responsiveness to nitrogen (N) fertilization depends on
the yield under non-limiting N supply as well as on the inherent productivity under zero N …

Nitrogen fertilizer application is an important method for the production of high-quality maize.
However, nitrogen fertilizer addition patterns vary according to regional climate, field …

Many soil and weather variables can affect the economical optimum nitrogen (N) rate
(EONR) for maize. We classified 54 potential factors as dynamic (change rapidly over time …

In Maine, potato yield is consistent, 38 t· ha− 1, for last 10 years except 2016 (44 t· ha− 1)
which confirms that increasing the yield and quality of potatoes with current fertilization …

One challenge in precision nitrogen (N) management is the uncertainty in future weather
conditions at the time of decision-making. Crop growth models require a full season of …

Applying at the economic optimal nitrogen rate (EONR) has the potential to increase
nitrogen (N) fertilization efficiency and profits while reducing negative environmental …

Core Ideas A 8‐yr study of corn N fertilization on high‐yielding fields in Québec, eastern
Canada. Grain yield response to N rates varied among site‐years. The economically optimal …
