Based on prices in 1950, adjusted for inflation to 2020, cotton should be $4.35/lb.

Accounting for yield increases and inflation, to gross the same money per acre as they did in 1950, the market should be $1.38 on an 850 lb yield.

Based on prices in 1950, adjusted for inflation to 2020, corn should be $16.32/bu. This assumes demand is unchanged.

Accounting for yield increases and inflation, to gross the same money per acre as they did in 1950, the market should be $3.53 on a 175 bu yield.

Based on prices in 1950, adjusted for inflation to 2020, soybeans should be $26.87/bu. This assumes demand is unchanged.

Accounting for yield increases and inflation, to gross the same money per acre as they did in 1950, the market should be $11.50 on a 51 bu yield.

Based on prices in 1950, adjusted for inflation to 2020, peanuts should be $2372/ton. This assumes demand is unchanged.

Accounting for yield increases and inflation, to gross the same money per acre as they did in 1950, the market should be $509 on a 4185lb yield.

Assuming my math is right, & based on the numbers figuring yield increases,

peanuts are underpriced ~27%
soybeans are over ~8%
corn is over ~25%
cotton is under ~85%

That’s partly why cotton farmers in GA are fed up. There is no $ to be made, and hasn’t been for several years.
