- •
The agronomic efficiency of applied N varied from 5 to 14 kg DM yield per kg N applied.
- •
The physiological efficiency varied from 79 to 123 kg DM yield per kg N uptake.
- •
The average indigenous soil N supply was about 100 kg N ha−1 per harvest cycle.
- •
The yield performance of the unfertilized poplar is encouraging.
- •
The rise of N content is detrimental for the quality of the feedstock product.
