After harvest a lot of straws are left behind. Some machine – I understand it is a roundpressmachine (one word in danish) – made a lot of rolls, compressing the straws for easier transportation. I also understand that a squarepresser uses more energy than the roundpresser, but squarepressed straws are cheaper to transport because of their form.
Round bales in the field make a beautiful pastoral picture!
Thanks for the information, too.
