August soybeans rose 13 1/4 cents, September corn gained 6 1/2 cents and wheat futures also advanced in early-week trade, leaving row-crop markets broadly higher Sunday evening.
Traders kept adding weather premium despite decent U.S. Grain Belt weekend rain and cooler forecasts, judging risks around upcoming corn pollination still high enough to support prices.
European drought added to that support, with corn and oilseed crops there seen facing serious production challenges that could tighten the global supply outlook.
The move extends last week's technically driven rally, which continued after late-June USDA reports landed without major surprises.
