A bill to revise the price support level, and implement a marketing loan program, for the 1988 through 1990 crops of soybeans under the Agricultural Act of 1949.

Amends the Agricultural Act of 1949 to set 1988 through 1990 soybean support prices at $5.02 per bushel. (Currently such levels are a minimum of $4.50 per bushel for 1988 through 1990.)

Requires (current law authorizes) soybean loan repayment at the lesser of prevailing world prices or the crop loan level.

States that if producers of any crop are permitted to repay loans at less than the crop's loan level, cottonseed and sunflower seed prices shall be supported at traditional soybean-based levels.
