Installation to be applied to self-propelled or tow-type agricultural seeders that comprises a general command central unit (5) fed from an electric power source and controls a corresponding individual control unit (10) that regulates the operation of the electro-pneumatic unit (6) associated to the seed dosing devices within the seeder to perform the pneumatic action. Electro-pneumatic unit may be a motor suction or a motor compressor unit. The invention envisages the association of these units to all the dosing devices in a seeding body of the seeder, to pairs of dosing units in the seeder, or else, on an individual basis, to each seed dosing device of the seeder.
