Corn and Soybeans declined on Monday as farmers increased planting of the two crops boosted by average rainfall that brought favorable planting conditions.

Corn futures for July delivery declined by 0.5 percent or 3 cents to $6.095 a bushel on the Chicago Board of Trade, and prices advanced by 3.9 percent last week reaching the highest record of $6.2425 on May 2.

The decline of corn decline was also attributed to a gain of the dollar that raised concern of the grain becoming more expensive to overseas importers.

Soybean futures for July delivery fell by 0.1 percent or 1.5 cents to $13.03 a bushel, and prices gained 9.8 percent in April.

Soybean futures rose by 78 percent in the past 12 months posting the highest gain of $15.8625 on March 3 after U.S. farmers reduced planting of the beans.

Planting of Soybeans was forecast to increase by 7 percent compared with 8 percent last year.
