1. A method for dispensing in a target area, a particulate material, the method comprising the steps of:
(i) providing a reservoir for the particulate material, said reservoir comprising a number of openings, suitable to allow particulate material to exit from the reservoir;
(ii) providing a number of closing means suitable for at least partially closing the openings of the reservoir;
(iii) providing a number of screens in the void of the reservoir, said screens being movable, through the void of the reservoir between at least a first and a second position;
(iv) loading particulate material in the reservoir; and
(v) moving the reservoir loaded with particulate material over the target area and at least partially opening the number of openings while alternatingly moving the screens between the first and the second positions and vice versa;
wherein in the movement between the first and the second positions, the closing of the openings by the closing means is changed.
