Abstract: Methods and apparatus are provided for dispensing chemical material, and in particular, granular, agricultural material, from a moving device driven over terrain to be treated with the material. A metering system for dispersing the material includes on apertured metering disk positioned above a rotatable impeller. The apertured disk meters material from a product container, by gravity feed, onto the impeller below at a rate proportional to the linear speed at which the apparatus is driven to dispense material at a uniform density over the terrain. The metering disk is a component of a product container which is removably mounted to the device. The impeller rotates at a constant speed to disperse the deposited material at a uniform distance from the apparatus, and the position on which the material is deposited on the impeller is adjustable.
