The per-acre price reported here is the arithmetic mean of the parcel per-acre prices, what might be thought of as the price of a typical acre. This number is what you'll also find on the Farmland Sales section of MLE Map. If you want instead to calculate the average price of a sold acre, you should calculate first the sum of the total sale prices, then the sum of the parcel sizes. Dividing the first by the second gives you a size-adjusted mean.
