Overnight developments

Beans, corn & wheat are all a little firmer in overnight trade with beans up 10-15c in a rebound from last night's steep losses supported by the ongoing strike in Argentina.

Corn is mostly 2-4c firmer on speculation that weather-delayed planting will reduce yield potential

Wheat is around 7-8c firmer on demand prospects from Iran and Brazil. Before today however, wheat has fallen 4.1 percent this week, heading for the sixth straight weekly decline.
