# Brazil crop concerns could provide support for U.S. Corn - Brownfield Ag News

> Analyst Jeff Peterson of Heartland Farm Partners says abnormally wet conditions in southern Brazil could slow first-crop corn planting. Dry conditions in northern Brazil could also delay soybean planting and therefore the safrinha corn crop, which makes up about 75% of Brazil's output.
