These tall weeds are what happened when a new field that did not yet have grasses established was allowed to grow without mowing or grazing. After the fields finally were grazed we ran the mower over and the tall weeds are no more. Though the cattle would wrap their long tongue around the top of the weeds and pull off the entire head. I believe these weeds were high in calcium because of their strong stems which benefited the cattle.
