The Soil Fertility Clock (SFC) concept is based on the assumption that the critical content
(range) of essential nutrients in the soil is adapted to the requirements of the most sensitive …

The agricultural sector is responsible for substantial amounts of greenhouse gas emissions
that exacerbate climate change. Such greenhouse gas emissions from upland crops are …

Groundwater nitrate contamination is a significant concern in agricultural watersheds
worldwide with it becoming a more pervasive problem in the last three decades. Models are …

As we face today's large-scale agricultural issues, the need for robust methods of
agricultural forecasting has never been clearer. Yet, the accuracy and precision of our …

In rainfed crop production regions such as the US Corn belt, the existence of a shallow water
table increases crop productivity, decreases inter-annual grain yield variability, and impacts …

CONTEXT Process-based models are increasingly used to explain and predict crop yields
and long-term changes in soil organic matter (SOM) and hence should be regularly …

CONTEXT While climate change threatens maize growth and production, appropriate N
fertilizer use (N) can help mitigate this threat and stabilize or improve maize yields. Accurate …

For decades, agronomists have invested time and resources to identify the optimum nitrogen
(N) rates for cereal crops. The most common method for estimating the agronomic optimum …

Limited knowledge about how nitrogen (N) dynamics are affected by climate change,
weather variability, and crop management is a major barrier to improving the productivity …

Multiple strategies are available that could reduce nitrogen (N) fertilizer use in agricultural
systems, ranging from voluntary adoption of new N management practices by farmers to …
