An agricultural material distribution means incorporated in a mobile spreading apparatus (141) for spreading wetted fertilizer materials or liming agents to the land is disclosed. The distribution means includes a plurality of agricultural material distribution heads (157), spaced apart from each other and operatively connected by a material supply means (200) wherein the flow of the fertilizer materials or liming agents into each of the distribution heads can be individually controlled. The mobile spreading apparatus further including a plurality of bins (115, 116, 143, 145, 149) or compartments adapted to contain and separate different materials for spreading, wherein the plurality of compartments are each operatively connected to the distribution means to allow the materials to be expelled via distribution heads. Preferably, the apparatus further includes a plurality of mixing means (161) adapted to mix the fertilizer material(s) or liming agent(s) with liquid, wherein the plurality of compartments, plurality of mixing means and the distribution means are operatively connected to each other so that the fertilizer material(s) or liming agent(s) from each of the compartments can be delivered via delivery means to be mixed together to the plurality of mixing means and then delivered to the distribution means to be expelled out from the each of the distribution heads of the distribution means. A control system capable of storing data or information relating to an area of land including the desired nutrient and/or lime application rates for specific regions of the area of land is also disclosed. Preferably, the apparatus includes a sensor adapted to sense at least one parameter of the soil or vegetation in the vicinity of the apparatus as the apparatus moves over the land, and to provide information to the control system. Preferably, the control system is capable of processing pre-loaded data and/or data received while moving over the land, and of controlling the rate at which material is supplied from each of the compartments as the apparatus moves over the land. The control system controls the mixing and distribution of the fertilizer materials and liming agents so as distribute in an area only that which that area requires. |
