A spreader for spreading treatment products on soil to improve the quality thereof are disclosed. The spreader consists of a vehicle including a frame (103) slidably housing an assembly (105, 106) of a hopper and a metering device. The frame also supports soil shearing means (114) located ahead of the hopper, and mixing means (112) located behind the hopper for mixing together the spread product and the loosened soil. As a result, soil treatment may be enhanced and the nuisance caused by spreading may be diminished.
