The effects of different distributor head types, air velocities and fertilizing rates on flow evenness for some fertilizers

In this study, three different types of distributor head (T, funnel and Y) were tested at three air velocities of 26, 31 and 36 ms-1, and three different fertilizing rates were selected as 12, 16 and 20 kg da-1 for two different fertilizers having nitrogen (calcium ammonium nitrate and urea). The best results of flow evenness were obtained with the T type distributor head at the air velocity of 26 m s-1 and fertilizing rate of 20 kg da-1 for both calcium ammonium nitrate and urea. In addition, an increase in fertilizing rate had a positive effect on flow evenness.
