Abstract
In the Sudan much of the clay plain lying between the Blue and White Niles south of the 25-in. isohyet is covered by an Acacia seyal woodland. As several hitherto undeveloped areas of this woodland, especially those alongside the railway line running from Sennar to Roseires, may prove suitable for mechanized rain-fed agriculture, or for irrigation from the Blue Nile, preliminary work on clearing Acacia seyal by ring-barking and with 2,4,5-T applied as a bark paint was started at Central Rainlands Research Station, Tozi, in late 1953. Normally on new schemes in this area woodland is cleared and stumped by hand. The contract charge for this in fairly thick woodland is around £8 an acre, and it was thought that ring-barking or chemical treatment might reduce this cost. In addition to the work recorded here trials on clearing the woodland mechanically were started at Tozi in the 1955/56 dry season.
