Approximately 1,500 pounds of seed potatoes are needed to plant 1 acre with 30 rows and 15-inch plant spacing. This calculation is based on an average planting rate of 8-10 pounds of seed potatoes per 100 feet of row, which translates to around 400-500 pounds per acre.

Soybean yieldsAn acre is measured by an area whereas a bushel is measured by weight. An acre of ground is 43,560 square feet. Producers will plant soybeans on ground and depending on hybrid, weather, soil fertility and many other variables, the bushels of soybeans that the ground will produce will vary. The National average soybean yield is hovering around 40 bushels per acre. The record was in Missouri in 2010, at 160 bushels an acre.
In 2006, the US produced 3.197 billion bushels of soybeans from 74.6 million acres with an average yield of just under 43 bushels per acre.

An acre is a measurement of area, not weight. There is no number of pounds that make an acre. It's the same as a square inch, you can't ask how much it weighs because it isn't something you can weigh.
It can vary a lot by year, location, weather, and many other factors, but the US average over the last couple of years was about 800 pounds per acre.
