Nitrogen (N) is an essential but generally limiting nutrient for biological systems.
Development of the Haber-Bosch industrial process for ammonia synthesis helped to relieve …

Interactions among soil water processes and the nitrogen (N) cycle govern biological
productivity and environmental outcomes in the earth's critical zone. Soil water influences …

Cover crops are well recognized as a tool to reduce NO3− leaching from agroecosystems.
However, their effectiveness varies from site to site and year to year depending on soil, cash …

Inclusion of a rye cover crop into maize-based systems can offer environmental benefits, but
adoption of the practice in the US Midwest is still low. This is related to the possible risk of …

Increasing nitrogen (N)-use efficiency (NUE) is key to improving crop production while
mitigating ecologically-damaging environmental N losses. Traditional approaches to assess …

Excessive phosphorus (P) applications to croplands can contribute to eutrophication of
surface waters through surface runoff and subsurface (leaching) losses. We analyzed …

Scientists have dedicated many decades and resources to studying the effects of tillage on
soil properties and crop yields. However, the literature lacks empirical data on corn/soybean …

There is a strong link between nitrate (NO 3-N) leaching from fertilized annual crops and the
rate of nitrogen (N) fertilizer input. However, this leaching-fertilizer relationship is poorly …

Subsurface nitrogen (N) losses represent a major environmental concern in agriculture,
particularly from fields containing artificial drainage to prevent saturated soil conditions and …

Progress on reducing nutrient loss from annual croplands has been hampered by perceived
conflicts between short‐term profitability and long‐term stewardship, but these may be …
