Abstract: This invention relates to an apparatus for travelling over a ground surface, the apparatus including detection means for detecting an area of the ground surface (or sub-ground surface) which has had a deposition of excreta, and treatment means for treating the area with at least one substance. The apparatus may preferably be automated. In a preferred embodiment, the excreta being detected may be cattle urine and the substance(s) used to treat the area of deposition of urine may be a nitrate inhibitor and/or a urease inhibitor.

Abstract: A truck mounted particulate material ground spreading apparatus mixes substantially dry particulate material with from 7-20% of water w/w immediately before supplying the wetted particles to a spreader disc to spread the wetted particles onto the ground. The apparatus (4) has a plurality of grinding discs (12a, 12b, 12c) above a mixing chamber (7) so that particulate material can be dry ground before mixing with water in the mixing chamber (7) and delivery to the spreader disc (19). The grinding discs (12a, 12b, 12c) and spreader disc (19) are mounted on a common shaft (14) driven by a hydraulic motor.

Abstract: A fertiliser composition in the form of granules or prills where urea has been coated with wet ground sulphur. The wet ground sulphur is preferably applied serially and/or simultaneously with one or both of a nitrification inhibitor and a urease inhibitor.
