BT23 Updates for Med $70
BT23 update using the 2025 baseline and starting results in 2024 for Med $70 with updated budgets. Cost updates include: 1) Increased the nitrogen application for the following crops: willow, camelina, carinata, pennycress, and willow. 2) Removed roundup during establishment for the following crops: camelina. 3) Harvest costs were updated because the combine width was adjusted. This affected the following crops: barley, camelina, carinata, corn, oat, pennycress, rice, sorghum, soybean, and wheat. 4) Harvest cost was updated with biomass sorghum because an additional tractor was added to pull the high dump forage wagon, and the wagon width was adjusted to not constrain the harvest operation with the combine. 5) Added poplar in the ag budget database for regions 1 and 13.
