A systematic review of factors that influence farmers' adoption of sustainable crop farming practices: Lessons for sustainable nitrogen management in South Asia

Journal of Sustainable Agriculture and Environment, 2022
Despite the fact that sustainable agricultural technologies and practices have been developed and introduced to farmers in both developed and developing countries, there are concerns about low levels of adoption.

Quantifying N response and N use efficiency in Rice-Wheat (RW) cropping systems under different water management [PDF]

, 2009
About 0·10 of the food supply in China is produced in rice¿wheat (RW) cropping systems. In recent decades, nitrogen (N) input associated with intensification has increased much more rapidly than N use in these systems.

Using a field radiometer to estimate instantaneous sky clearness Radiômetro de campo para cálculo da clareza instantânea do céu

Revista Brasileira de Engenharia Agrícola e Ambiental, 2006
Reflectance measurements of crop plants and canopies show promise for guiding within-season, variable-rate nitrogen (N) application. Most research results have been obtained around solar noon with clear skies.

Agroecosystems, Nitrogen-use Efficiency, and Nitrogen Management

AMBIO: A Journal of the Human Environment, 2002
The global challenge of meeting increased food demand and protecting environmental quality will be won or lost in cropping systems that produce maize, rice, and wheat. Achieving synchrony between N supply and crop demand without excess or deficiency is the key to optimizing trade-offs amongst yield, profit, and environmental protection in both large ...

Pennycress as a Cash Cover-Crop: Improving the Sustainability of Sweet Corn Production Systems

Agronomy, 2020
Commercial sweet corn (Zea mays convar. saccharata var. rugosa) production has a proportionally high potential for nutrient loss to waterways, due to its high nitrogen (N) requirements and low N use efficiency.

Self-reseeding annual legumes for cover cropping in rainfed managed olive orchards

Spanish Journal of Agricultural Research, 2015
Given the environmental impact of nitrogen (N)-fertilizer manufacture and use, the sustainable management of agro-systems should be sought by growing N-fixing legumes.

Climate Change Increases Nitrogen Concentration in Rice With Low Nitrogen Use Efficiency

Earth's Future, 2021
Growing evidence indicates that climate change has significant impacts on crop production. However, the spatial variability and extent of the impacts on N concentrations in crops have yet to be explicitly described, although N concentration is a critical

Accumulation of Wheat Phenolic Acids under Different Nitrogen Rates and Growing Environments

Plants, 2022
The health benefits of whole wheat grains are partially attributed to their phenolic acid composition, especially that of trans-ferulic acid (TFA), which is a powerful natural antioxidant.
