Guessing hay yields quantitatively is a fool’s game and I’ve been doing this on my own for 40 years. I know when we’re above or below average but almost never by how much. My long term average is slightly above 100 bales per ac but my first piece this year was less than 60/ac. I knew it was bad, just not how badIf the grasses are knee high, would it be possible to guesstimate the number of small bales per acre? My goal is to reach 40 bales per acre per cutting.
