As the price of fertiliser rises, so does the value of the straw that stays on your farm.
The Excel spreadsheet below allows you to calculate the economic cost of straw nutrient losses from your farm. The figures for bale weight (written in red text) can be altered to match your farm practice. Click the link to download the spreadsheet - then once you have opened it, click 'Enable editing' in the yellow row at the top of the spreadsheet. This allows you to alter bale size.
