To know the fertiliser flow exiting onlyone adjustment shutter, divide the FT value by 2.DL: is the amount of fertiliser you wish to spread ex-pressed in (kg/ha).WL: is the working width expressed in (m).VL: is the working speed expressed in (km/h).Calculation of the fertiliser dose (kg/ha)DL = FT · 600WL · VL[kg/ha] (4.8)where:DL: is the amount of fertiliser you wish to spread ex-pressed in (kg/ha).FT : is the total fertiliser flow value (kg/min) exiting thefertiliser spreader.WL: is the working width expressed in (m).VL: is the working speed expressed in (km/h).Cod.
