# U.S. grains: Soy, corn rise on decline in crop conditions - Grainews

> US soybean and corn futures rose on 17 July after USDA reported that good-to-excellent ratings fell to 69% for soybeans and 72% for corn, down from the prior week. Hot, dry weather drove the decline, and traders also hoped for a resolution to the US-China trade dispute.

## Why it matters
