An overview of crop nitrogen status assessment using hyperspectral remote sensing: Current status and perspectives
Nitrogen (N) is significantly related to crop photosynthetic capacity. Over-and-under-
application of N fertilizers not only limits crop productivity but also leads to negative …

Integrated nitrogen management strategies to improve seed yield, oil content and nitrogen efficiency of winter oilseed rape (Brassica napus L.): a review
Winter oilseed rape (Brassica napus L.) is the dominant oilseed crop in northern Europe.
Generally, it requires high amounts of nitrogen (N) but is characterized by low N-efficiency …
