Seedbed: Does fertilizing to crop removal make sense?

Keep in mind that every field will eventually reach a point where it just doesn’t make sense to keep adding more fertilizer with no possibility of an economic return

“I didn’t get around to taking a soil test. We’ll just replace what the crop is taking out. That should be close enough.”

Have you ever used this excuse? And have you ever thought about what it might be costing you?

The number of fields fertilized to crop removal seems to be increasing. Some of this may be an unfortunate consequence of including crop removal as part of the nutrient management software, implying that the Ontario Ministry of Agriculture, Food and Rural Affairs now “approves of” crop removal for fertilizer recommendations, the same as our neighbours to the south.
