July 30 (Reuters) - U.S. agriscience company Corteva ( CTVA )

on Thursday raised it forecast for full-year adjusted

profit, based on strong demand across key crop markets.

The acreage shift toward soybeans and away from corn is

expected to support demand for seed traits, as farmers adjust

planting decisions in response to higher input costs and tighter

margins.

In the second quarter, crop prices were mixed, as corn and

soybeans gained on expectations of reduced U.S. plantings, while

wheat remained under pressure from abundant global supplies.

The company now expects full-year adjusted earnings between

$3.60 to $3.80 per share, up from a prior view of $3.45-$3.70

per share.
