This invention relates to a vehicle for spreading a particulate material over a ground surface, the vehicle including at least one store of a particulate material, a spreading means for spreading the particulate material over the ground surface, a conveying means for conveying the particulate material from the at least one store to the spreading means. The invention further includes a wetting apparatus for wetting the particulate material prior to, or during, the spreading of the particulate material over the ground surface, by the spreading means. The invention may be particularly suitable for encouraging or maximising foliar uptake of fertiliser, as well as minimising spray drift during the spreading of the fertiliser.
