You could very well be right, we'll need a maize drilling picture thread in a few weeks.Chalk not the best soil for maize so I like it to be warm. many of my fields turn white with the chalk when it rains after planting maize and i always think that the chalk is reflecting some of the heat.

Got all 70 acres of beans in last week same as you, did 12 of 70 acres of spring barley on the lighter side of the 70 acre field but the heavy land which is stubble/dead cover crop and will be drilled direct is going to take some drying out, so 58 acres still to do. Would normally be in by now with plough-powerharrow-tine drill system but patience required for spring strip-till drilling with the DTS. Your not the only one don't worry.ive got 185 acres still to put in, spring barley and wheat. The beans went in last week before the rain. I feel I'm the only one with something to do,make me feel better..
