Winter wheat genotype ability to recover nitrogen supply by precedent crops under combined nitrogen and water scenarios

M. D. Raya-Sereno et al.

Summary: The objective of this study was to test the ability of different wheat genotypes to take up nitrogen from preceding legume crops under different water scenarios. The results showed that drought-tolerant genotypes had higher nitrogen nutrition index, biomass, yield, and nitrogen output under low water and nitrogen inputs, while other genotypes performed better under non-limiting conditions. Therefore, this study confirms differences between wheat genotypes in nitrogen uptake from preceding legumes in crop rotations under different water levels and highlights the potential of nitrogen nutrition index to assess wheat nitrogen status.

Climate change unequally affects nitrogen use and losses in global croplands

Chenchen Ren et al.

Summary: Quantification of the impact of climate change on crop yield and nitrogen use efficiency reveals global inequalities in agricultural nitrogen use and losses. Farm size plays a crucial role in regulating nitrogen use for climate adaptation. The study emphasizes the importance of reducing global inequalities in agricultural nitrogen use and losses to sustain global agricultural production and reduce pollution.

Nitrogen dynamics in cropping systems under Mediterranean climate: a systemic analysis

Luis Lassaletta et al.

Summary: In Mediterranean cropping systems, sustainable nitrogen management requires practices to be specifically adapted to the local agro-environmental characteristics, with a special emphasis on water availability for rainfed and irrigated systems. This approach should also include a systemic analysis of nitrogen input into the territory driven by the configuration of the agro-food system.

Higher yields and more biodiversity on smaller farms

Vincent Ricciardi et al.

Summary: This study reveals that smaller farms have higher yields and biodiversity compared to larger farms, with little difference in greenhouse gas emissions and profits. The findings emphasize the importance of farm size in mediating environmental and social outcomes relevant to sustainable development.

Simultaneous assessment of nitrogen and water status in winter wheat using hyperspectral and thermal sensors

J. L. Pancorbo et al.

Summary: Remote sensing technology is a valuable tool for reducing environmental impact in agriculture by detecting crop nitrogen and water status. This study evaluated the potential of visible and infrared hyperspectral and thermal imaging sensors to assess nitrogen and water status with reduced confounding effects. The combination of spectral and thermal information improved the adjustment of N fertilization and irrigation to crop requirements.

Reshaping the European agro-food system and closing its nitrogen cycle: The potential of combining dietary change, agroecology, and circularity

Gilles Billen et al.

Summary: The article explores how nitrogen losses in Europe's agro-food system can be drastically reduced by changing dietary habits, promoting organic crop rotation systems, and reconnecting livestock with cropping systems, allowing for feeding the projected European population in 2050 without feed imports and with half the current level of environmental nitrogen losses.

Quantification of global and national nitrogen budgets for crop production

Xin Zhang et al.

Summary: Input-output estimates of nitrogen on cropland are essential for improving nitrogen management and understanding the global nitrogen cycle. While most datasets show similar patterns, some annual estimates vary widely, leading to large ranges of uncertainty. The comparison of nitrogen budget terms by country reveals areas for improvement.
