Single-disc rotary fertilizer spreaders are principally used to obtain a full fertilizer distribution pattern. These spreaders also can be used for banding application if the spreader disc is simultaneously fed by two orifices with the same shape and size. Using two orifices at the opposite angular position of 180 degrees and the proper angular position with respect to travel direction resulted in two bands on opposite sides of the spreader The single-disc spreader used for this study was evaluated for spreader disc height and PTO speed to control the spacing between the two bands and bandwidths. Spreader disc heights of 38, 56, and 75 cm and PTO speeds of 270, 405, and 540 rpm were used to demonstrate the effects of these variables on band spacing and width. Using triple superphosphate, band spacings from 4 to 11 m and bandwidths from 4 m left/4 m right to 9.5 m left/9.5 m right were obtained. The effect of PTO speed was more pronounced than the effect of spreader disc height for both band spacing and bandwidth. The effect of spreader disc height on both left and right bandwidth was not proportional.
