Nowadays farmers can eliminate them from cereal crops using selective herbicides that don't kill members of the family of grasses (wheat, etc). But there is what is known as the fossil seed bank = a reservoir of seeds buried in the soil that can germinate after many years given the right conditions. Maybe this farmer had a new plough which went a little deeper, maybe it was the wet. The selective herbicides can't be used on rape, becaue it's not a grass, so they would kill it along with the weeds. Some farmers are choosing to reduce their agrochemical interventions to a minimum, anyway, and cornflowers don't do any harm to the crop. The cornflowers have always been there, but this year they were on top form.Pollygarterhttps://www.blogger.com/profile/10519711639714303756noreply@blogger.comtag:blogger.com,1999:blog-3373240096673970831.post-73808804345446839592014-06-18T09:37:53.076+02:002014-06-18T09:37:53.076+02:00How do you think the cornflowers got there?How do you think the cornflowers got there?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3373240096673970831.post-39752080906922204062014-06-18T07:33:27.833+02:002014-06-18T07:33:27.833+02:00It does look lovely and with a sand and gravel pit...It does look lovely and with a sand and gravel pit nearby it must be a great place to find all sorts of bees.
