The number of ha doses is 1,6 as an average for all plant growth during the year 2000. It´s a rather normal figure for Wiggeby where grain are the dominating crops. If treatment will be with only herbicides in normal dose it gives the figure 1,0 ha doses. In the fields with nr 5,6,20,37 and 41 are grown oats and into field 21and 22 barley. With a well adapted equipment the doses are lower then recommended which results in a more low ha dose. In field nr 10,17,18,23,24,25 and 26 are grown winter wheat with a more high ha doses depending on treatment with both herbicides and fungicides.
