As slurry spreading systems get bigger in the move to greater output, there is a constant challenge between field surface damage and soil compaction both competing with the need to get the ground covered fast. Soil conditions are the ultimate arbiter of spreading ability and the poorer the soil conditions in terms of soil moisture levels, the more difficult the spreading challenge becomes.Tractor and tanker systems have notable problems in soft ground conditions, usually just when the slurry spreading season starts to open. These problems have forced many farmers and contractors to look at the advantages of umbilical or pipeline slurry spreading systems to minimise loading the soil.
