Nitrogen (N) is a key macronutrient whose availability often determines maize growth and productivity. Improving nitrogen use efficiency (NUE) is critical to increase maize yield while reducing N inpu
High NUE (nitrogen use efficiency) has great practical significance for sustainable crop production. Wheat is one of the main cultivated crops worldwide for human food and nutrition. However, wheat gr
Grassland production is sensitive to both precipitation and plant N accumulation and utilization, such that change in one variable influences grassland response to the second variable. We investigat
