Cover crops (CCs) are widely promoted for reducing nitrate leaching and enhancing soil fertility, yet their role in regulating winter nitrous oxide (N 2 O) emissions remains poorly understood. This field study assessed how termination timing of oil radish ( Raphanus sativus ) influenced soil mineral nitrogen (SMN) dynamics and winter N 2 O emissions across five site-years in a humid temperate climate (Germany) on contrasting s...

Winter cover crops (CCs) provide substantial agronomic and environmental benefits, yet their influence on nitrogen (N) fertilization requirements and yield outcomes for subsequent crops remains underexplored. This study investigates the economic optimal nitrogen rates (EONRs) and corresponding yield effects for first (silage maize or sugar beet) and second (winter wheat) succeeding crops following CCs. Four CC species from dif...

Nitrogen (N) fertilization to crops might lead to formation and release of reactive N—e.g. nitrate, ammonium, ammonia, nitrous oxide (N 2 O) —, contributing to eutrophication, atmospheric pollution, and climate change. Use of nitrification inhibitors and splitting of N fertilizer may reduce the N 2 O emission from arable soils cropped with winter wheat. We tested different N fertilizers treated with 3,4-dimethylpyrazol phospha...

Winter oilseed rape (WOSR) is the major oil crop cultivated in Europe and the most important feedstock for biodiesel. Up to 90% of the greenhouse gas (GHG) emissions from biodiesel production can occur during oilseed rape cultivation. Therefore, mitigation strategies are required and need to focus on direct nitrous oxide (N 2 O) emission as one of the largest GHG contributors in biodiesel production. Earlier studies show that...
