The USDA March 31 Prospective Plantings report set out 2017 row crop and spring wheat intentions, and the market's focus has shifted to spring and season weather. Conditions are mostly favorable, with California moving from drought concerns to flood control after heavy rains and snowpack.
Favorable planting weather points to adequate crop supplies, which is bearish for feed grain prices, though the season is still open to weather risk.
