WHEAT - Up 1 to 4 cents

CBOT wheat Wv1 firm on a weak U.S. dollar and technical support. Improved soil moisture in parts of the Plains wheat belt following weekend rains capping the market.

CORN - Steady to 3 cents higher

Rainy weather slowed early planting progress in the U.S. Midwest.

CBOT May corn CK25 was last 3 cents higher at $4.85-1/4 per bushel.

SOYBEANS - Up 1 to 4 cents

Soybeans firm on a weaker dollar and relief that U.S. agriculture exports were shielded from port fees on China-built vessels. Gains capped by worries over rising U.S.-China trade tensions.

Rains across the U.S. Midwest stalled early planting progress.
