Nitrogen fertilizer is applied in the spring following a harvest, herbicide is used in non-harvest years, and a pesticide is used every year.
Nitrogen fertilizer is applied at a rate of 56 kg N per application. N2O emissions from fertilizer and decaying biomass are calculated using the Farm Energy Analysis Tool (FEAT).
After 6 harvests (Year 21, counting site prep and nursery operations) the stumps are ground down on site and herbicide is applied to the soil.
Irrigation is only assumed to be needed for nursery operations.
Greenwood Resources has shown both irrigated and non-irrigated to be viable practices for poplar growth depending on location.
