A method of sowing seed (including fertilised pellets, parti- cles, crystals and the like) comprises accelerating the seed to a speed in the supersonic range and directing the so moving seed to impinge on penetrable sowing ground so that the seed penetrates the ground to approximately the desired depth. The operation is carried out in a relatively low pressure environment and a feature of the operation is that the seed can penetrate the ground without substantial damage to the seed. Appropriate apparatus is pro- vided to accelerate the seed to the supersonic speed range in a low pressure environment, and in one example this comprises a rotor wheel (30) receiving seed appropriately from a supply source (40), a sufficient rotary speed being imparted to the wheel for the ne- cessary acceleration of the seed which is discharged via an outlet (35) in the wheel. Alternative apparatus comprises a low pressure fluid source (9) far seed acceleration via a ducting system (3, 4) and in another example electrostatically charged seed is accelerat- ed by an electrical conductor system (55 A, B).
