PCT No. PCT/CH85/00091 Sec. 371 Date Feb. 11, 1986 Sec. 102(e) Date Feb. 11, 1986 PCT Filed Jun. 3, 1985 PCT Pub. No. WO86/00001 PCT Pub. Date Jan. 3, 1986.The seed pellets have a core which contains grains of seed, organic substrate, loess, organic fertilizer, fungicides and, possibly, pesticides, and a wetting agent which promotes surface wettability. At least one bitter substance may also be present and made to cover the core in the form of a coat, or be distributed within the core. The core is furthermore provided, with a semipermeable coat, which consists of at least one starch and/or latex. The loess acts as a binding agent which serves to intimately bind the various constituents of the core to each other, and to act as a water storing agent in addition to the organic substrate. The semipermeable coat also contributes to the improvement and control of water conservation. Thus the pellets may be made to include sensitive seeds too which require much water for germination and/or may be sown in relatively dry regions and, furthermore, are resistant to breakage and abrasion.
