Soybeans Could Yield 100 Bushels Per Acre

Inside Dakota Ag

A field of soybeans that could yield 100 bushels per acre is a pretty amazing sight.

I saw a field of soybeans in South Dakota that I think could yield 100 bushels per acre.

It was on the Kory Standy farm south of Platte.

The soybeans were about chest high -- probably 4-½ feet tall -- and loaded from the top to bottom with pods.

Last year, Standy won the South Soybean Yield Contest with an entry of nearly 90 bushels per acre.

He’s thinking these will do a little better.

What’s his secret?

It’s part Mother Nature and part technology.

The field lies on a bend of the Missouri River. The soil is nearly pure silt, deposited Missouri River floods.

The field is subsurface drip irrigated. Water from the river is pumped through a 5/8-inch-diameter poly drip tape buried 14 inches below the soil surface and spaced 60 inches apart.

Standy puts 0.27 inches of water on the field every day, unless it rains.

And that’s it. Everything else he does is pretty conventional.

Next to the beans is a field of subsurface drip irrigated 112-day corn that looks good, too. Standy is thinking it might yield 250 bushels per acre. His corn seed rep thinks it will be better -- maybe 285.

Both fields were pretty amazing.
